Patent No. 6806890 JP 2020-191019 A

Meanwhile, the manufacturing management of steel frame products (steel frame components) still involves on-site staff manually writing on paper. However, because most steel frame products are manufactured on a made-to-order basis, it is necessary to keep the backlog of work-in-progress in the factory to an appropriate level while adhering to the delivery deadlines required by the customer. For this reason, manufacturing management of steel frame products is particularly important, and there is a demand for a method that allows for appropriate and efficient management.

The present invention has been made in consideration of the above problems, and provides a manufacturing management device for appropriately and efficiently managing the manufacturing of steel products (steel components).

The manufacturing management device of the first aspect has an acquisition unit, a generation unit, and an output unit. The acquisition unit acquires design information related to the design of steel frame members. The generation unit generates a list of steel frame members to be manufactured based on the design information. The output unit outputs the list generated by the generation unit.

The manufacturing management method includes an acquisition step, a generation step, and an output step. The acquisition step acquires design information related to the design of the steel frame members. The generation step generates a list of the steel frame members to be manufactured based on the design information. The output step outputs the list generated by the generation unit.

The manufacturing management device of the second aspect includes a communication unit, a progress update unit, and a screen generation unit. The communication unit is capable of communicating with a user terminal. The progress update unit updates the progress status of the manufacturing process of the update target when the communication unit receives from the user terminal a progress processing request representing a transition in the manufacturing process of the update target, the request including identification information assigned to the update target, which is any one of a steel frame product, a part used in the manufacture of a steel frame product, and a material used in the manufacture of the part. The screen generation unit is capable of generating a screen that reflects the update of the progress status of the update target by the progress update unit, and is capable of transmitting the generated screen to the user terminal via the communication unit.

The manufacturing management program is configured to cause the information processing device to function as a manufacturing management device of any of the above aspects.

The manufacturing management device of the present invention makes it possible to appropriately and efficiently manage the manufacturing of steel frame products.

As shown in FIG. 3, the server 20 includes a control unit 21, a memory unit 22, and a communication unit 23. The components are connected to each other via a bus so that they can communicate with each other. The control unit 21, memory unit 22, and communication unit 23 of the server 20 have the same functions as the control unit 11, memory unit 12, and communication unit 13 of the user terminal 10, so further explanation is omitted.

The memory unit 22 stores various information, such as design information regarding the design of the steel frame acquired by the acquisition unit 211 described below and progress information regarding the manufacturing status of the steel frame product accepted by the acceptance unit 212. The memory unit 22 may also store a list generated by the generation unit 213.

(Acquisition unit 211)
The acquisition unit 211 acquires design information related to the design of the steel frame. The acquisition unit 211 can acquire the design information related to the design of the steel frame, for example, from a design system 30 used when designing the steel frame.

Here, the design information is not particularly limited as long as it is information related to the design of the steel frame, but may include, for example, three-dimensional drawings, two-dimensional drawings, materials, sizes, and welding positions of the steel frame or steel frame products, and may also include the type, size, materials, and welding positions of the parts that make up the steel frame products. Furthermore, it may also include information such as blueprints, delivery dates, and customer names for buildings in which the steel frame is used. The design information may also be CAD data (including three-dimensional (3D) CAD data) created by software with computer-aided design (CAD) functions.

In addition, in this specification, a steel product is a component that constitutes a steel frame used in a building, and is manufactured to be delivered as a product. Steel frames include both heavy steel frames and light steel frames. Steel frame products include steel members manufactured by processing steel materials, as well as steel structures manufactured using multiple parts. Steel materials used for steel frames include general structural rolled steel materials (SS400, SS490), architectural structural rolled steel materials (SN400A, SN400B, SN400C), welded structural rolled steel materials (SM400, SM490), general structural carbon steel pipes (STK400, STK490), general structural square steel pipes (STKR400, STKR490), architectural structural cold roll formed square steel pipes (BCR295), general structural light steel (SSC400), etc.

In the first embodiment, the acquisition unit 211 may acquire design information related to the design of a steel frame from the design system 30. As described below, the design system 30 is a system used for designing steel frames and buildings using steel frames. The design system 30 may also be a system equipped with three-dimensional computer-aided design software or software including the software. The acquisition unit 211 can also acquire design information by acquiring and analyzing three-dimensional design data generated by the three-dimensional computer-aided design software.

(Reception unit 212)
In the first embodiment, the server 20 may have a reception unit 212 that receives input of progress information related to the manufacturing status of the steel frame product. The progress information may be received via the user terminal 10, or the server 20 may receive the input directly. When receiving the progress information via the user terminal 10, the user of each user terminal 10 inputs the progress status to the user terminal 10, and the server 20 can receive the input information via the network.

The progress information is not particularly limited as long as it is information that indicates the progress of manufacturing steel products, but includes, for example, information on the progress of primary processing of girders, sub-girders, and studs, the progress of tack installation, and the progress of welding; the progress of die assembly, the progress of welding, and the progress of UT (Ultrasonic testing); the progress of shaft cutting, the progress of grooves, and the progress of backing; the progress of joint installation, the progress of welding, and the progress of UT; the progress of column assembly, the progress of robot welding, the progress of part tack installation, and the progress of welding; the progress of acceptance inspection, and other various processes, the progress of manufacturing and processing of components, etc. The joint and shaft are mainly components of columns. The joint itself is manufactured using multiple components as parts. The progress is managed from the component level.

Progress information also includes information such as the location where the steel product will be manufactured or has been manufactured, the department and name of the person in charge of manufacturing the steel product, the planned date and time of each manufacturing process or the date and time of each process, the date and time when the information was entered, the planned date for manufacturing the steel components, and the delivery date of the steel product.

As mentioned above, the progress information includes the progress of the installation of the joints, but the progress of the installation of the joints includes the progress of each process related to the installation of the joints, such as the progress of the assembly of the joints, the progress of the robot welding, the progress of the temporary attachment of parts, the progress of the main welding, the progress of the UT, and the progress of the acceptance inspection.

(Generation unit 213)
The generating unit 213 generates a list of steel frame products to be manufactured based on the design information. In the list of steel frame products, design information is associated with each steel frame product based on the design information acquired by the acquiring unit 211. The list is also generated at the component level. Such a list is also included in the list of steel frame products in the broad sense. The list is output by the output unit 214 and displayed on the user terminal 10, as described below.

In the first embodiment, the generating unit 213 may generate a list that associates the design information acquired by the acquiring unit 211 with progress information regarding the manufacturing status of the steel product that is accepted by the accepting unit 212. The list in which the design information and the progress information are associated is output by the output unit 214 and displayed on the user terminal 10, as described below.

The generation unit 213 may also create a list that displays the progress status using different expressions for each progress status of the steel product manufacturing. For example, different colors may be used to indicate that the steel product manufacturing has been completed, that manufacturing is in progress, or that manufacturing has not yet been carried out. The size and font of the characters displayed in the list may also be changed for each progress status. The list that uses different expressions for each progress status of the steel product manufacturing is also output by the output unit 214 in association with the list, as described below, and displayed on the user terminal 10.

In the first embodiment, the generation unit 213 may generate an image showing a steel frame product based on the design information. The image showing a steel frame product may be a two-dimensional image or a three-dimensional image. The image may also be a drawing of the steel frame product, and may include various information contained in a typical drawing, such as not only the shape of the steel frame product, but also the dimensions and material of the steel frame product, joint surfaces, and installation location in a building. The image showing the steel frame product is output by the output unit 214 in association with the list, as described below, and displayed on the user terminal 10.

(Output unit 214)
The output unit 214 outputs the list generated by the generation unit 213. The list output by the output unit 214 is transmitted to the user terminal 10 via the network and displayed on the display unit 14 of the user terminal 10. A specific example of the list output by the output unit 214 is shown in Fig. 5. In Fig. 5, information indicating the materials, sizes, and progress status of parts used in the manufacture of a steel frame product is listed.

In the first embodiment, the output unit 214 outputs a list generated by the generation unit 213, which shows the progress status inputted and accepted by the acceptance unit 212 in association with the steel frame product. Specific examples of the list are shown in Figs. 6 and 7.

Figure 6 is a list that associates detailed information about columns, which are steel products, with progress information about the manufacture of the columns. The detailed information includes the floor line of the joint (e.g., 2FL means a joint for the second floor), the installation position of the joint, the number of arms of the joint, the number of dice required to install the joint, the number of shafts, etc. The progress information includes the progress status for each manufacturing process, such as the assembly of the joint, robot welding of the assembled joint, temporary attachment of parts including the joint, main welding, UT, and acceptance inspection. When the installation of the joint is complete (e.g., the row with the symbol 1CX1Y6), each process (represented as 組, ロボ, 仮, 融, UT, 入 in the figure, respectively) has been completed, so all the columns for each process are filled in and a check mark is placed in the acceptance inspection column. On the other hand, for components where welding of joints is not complete (for example, components with the codes 2CX1Y4 and 3CX1Y4), the joint assembly, robot welding, temporary attachment of parts, main welding and UT processes have been completed, so all of these columns are shown filled in, but the columns for the incomplete acceptance inspection processes are blank, and no check mark has been added to the acceptance inspection column. The codes are identification information assigned to steel products and parts used in steel products, etc.

Figure 7 is a list showing progress information for each work process in the manufacture of girders, joists, studs, dice, shafts, joints, and columns, and shows the ratio of the amount (number) completed at each process to the required production amount (number) of each steel product or part for each work process. In Figure 7, for example, there are 407 girders that need primary processing, of which 386 have had work completed, so the progress is shown as about 95% complete. In addition, there are 263 dice that need to be assembled, of which 263 have had work completed, so the progress is shown as 100%.

In the first embodiment, the output unit 214 may output an image showing a steel frame product or part generated by the generation unit 213 based on the design information in association with a selection (designation) on the list. For example, when a user selects a steel frame product on the list on the user terminal 10 to which the list has been output, an image showing the steel frame product is displayed on the user terminal 10. FIG. 8 shows a specific example of a list displayed on the user terminal 10, on which an image showing a column, which is a steel frame product, is superimposed as a pop-up. In the example of FIG. 8, a two-dimensional drawing of the column selected by the user is displayed as an image, but the image may be a three-dimensional drawing.

(Drawing display unit 215)
In the first embodiment, the server 20 may further include a drawing display unit 215 that displays steel frame products and parts in association with architectural drawings of a building to be constructed using the steel frame products and parts. For example, when a user selects a steel frame product or part on a list on the user terminal 10, the drawing display unit 215 can output a drawing showing which part of the architectural drawing the steel frame product or part corresponds to. The drawing may be generated by the generation unit 213.

In addition, the drawing display unit 215 may display the progress of the manufacturing of each steel frame product or part in association with the architectural drawing of the building to be constructed using the steel frame product or part. More specifically, the progress of the manufacturing of each steel frame product and each part acquired by the reception unit 212 can be displayed at the position where each steel frame product and each part is used on the architectural drawing of the building acquired by the acquisition unit 211. A specific example is shown in FIG. 9. The thick line parts in FIG. 9 indicate the positions where each steel frame product (beams, etc.) is placed, and I and II indicate work areas. In work area I, the manufacturing of the necessary steel frame products is completed or almost completed. In work area II, there is no steel frame product that has been manufactured, or there are very few of them. The drawing displayed in the drawing display unit 215 may be created by the generation unit 213, or may be output by the output unit 214 in association with the list.

(Ranking Unit 216)
In the first embodiment, the server 20 may have a ranking unit 216 that receives information on the priority of the manufacturing of steel frame products and parts, in addition to information on the progress of the manufacturing of steel frame products and parts. The erection date, which is the planned date when the steel frame product is used at the site and actually indicates the delivery date, is one of the information on the priority (FIG. 6). The information on the priority may be received by the ranking unit 216 via the user terminal 10, associated with each steel frame product and each part on the list by the generating unit 213, and output by the output unit 214. For example, the generating unit 213 can generate a list that displays steel frame products or parts in order of the manufacturing priority. Alternatively, the color of each steel frame product or each part can be changed according to the priority and displayed in the list.

(Notification unit 217)
In the first embodiment, the server 20 may have a notification unit 217 that notifies the user of progress information regarding the manufacturing status of steel frame products and parts. The notification unit 217 can notify the user of the progress status by, for example, sending a text email to the user terminal 10. More specifically, for example, the notification unit 217 can notify the user of the progress status by email or the like a certain period of time before a deadline such as the delivery date or the scheduled manufacturing completion date of each steel frame product. The method of notification by the notification unit 217 is not limited to email, and various message applications can be used to notify the user of the progress status or to notify the user of a link such as a URL.

(Warning display section 218)
In the first embodiment, the server 20 may have a warning display unit 218 that displays a warning when an abnormality occurs in the progress of the manufacturing of the steel frame product or parts. If the manufacturing of the steel frame product is not completed by the deadline, the warning display unit 218 can display an alert on the list. More specifically, the server 20 can display information such as the delivery date and the expected completion date of the steel frame product. If the receiving unit 212 does not receive progress information indicating that the manufacturing has been completed a certain period of time before the deadline, the generating unit 213 can generate a list with a warning display and the output unit 214 can output it. .

<Design System 30>
FIG. 10 is a block diagram showing a schematic configuration of the design system 30. As shown in FIG.

As shown in FIG. 10, the design system 30 includes a control unit 31, a memory unit 32, and a communication unit 33. The components are connected to each other via a bus so that they can communicate with each other. The control unit 31, memory unit 32, and communication unit 33 of the design system 30 have the same functions as the control unit 11, memory unit 12, and communication unit 13 of the user terminal 10, so further explanation is omitted.

The design system 30 is not particularly limited as long as it is a system used for designing steel structures, but for example, it is a computer equipped with software having computer-aided design (CAD) functions. The software may also have three-dimensional computer-aided design (3D CAD) functions, in which case the server 20 can obtain 3D CAD data from the design system 30 via a network.

Each component of the above system may include components other than those described above, or may not include some of the above components. Furthermore, each of the user terminal 10, the server 20, and the design system 30 may be composed of multiple devices, or may be integrated. Furthermore, a function described as being performed by a certain component may be performed by another component instead.

<Overview of Processing in Server 20>
Below, an overview of the processing in the server 20 will be described. Figures 11 to 13 are flowcharts showing the first to third steps in the first embodiment of the manufacturing management processing for steel frame products and parts executed in the server 20. The processing of the server 20 shown in the flowcharts is stored as a program in the storage unit 22 of the server 20, and is executed by the control unit 21 controlling each unit.

First, the first procedure in the first embodiment will be described with reference to FIG. 11. As shown in FIG. 11, the server 20 requests design information from the design system 30 via the network (S101), and the design system 30 sends the information to the server 20 (S102), causing the server 20 to acquire the design information (S103). The server 20 generates a list based on the acquired design information (S104) and outputs the list to the user terminal 10 (S105), and the list is displayed on the display unit 14 of the user terminal 10.

Next, the second procedure in the first embodiment will be described with reference to FIG. 12. Steps S201 to S203 are the same as steps S101 to S103 in the first procedure shown in FIG. 11, and therefore will not be described again. Having acquired the design information, the server 20 accepts progress information (S204) input via the user terminal 10 (S205). Next, the server 20 generates a list that associates the acquired design information and the accepted progress information based on the information (S206), outputs the list to the user terminal 10 (S207), and the list is displayed on the display unit 14 of the user terminal 10 (S208).

Next, the third procedure in the first embodiment will be described with reference to FIG. 13. Steps S301 to S306 are the same as steps S101 to S106 in the first procedure shown in FIG. 11, and therefore will not be described again. The server 20 accepts progress information (S307) input via the user terminal 10 (S308). Next, the server 20 again generates a list that associates the design information acquired in S303 and the progress information received in S308, based on the information (S309), and again outputs the list to the user terminal 10 (S310). The output list is displayed on the display unit 14 of the user terminal 10 (S311).

The first embodiment, which includes the execution of the first to third steps described above, provides the following advantages:

The server 20 acquires design information related to the design of steel frame members through the acquisition unit 211. Then, the generation unit 213 generates a list of steel frame products to be manufactured based on the design information, or parts to be used in the steel frame products, and the output unit 214 outputs the list. This makes it possible to manage the manufacture of steel frame products and parts by digital means using a network or computer, whereas in the past, design information was printed out on paper and managed by analog means based on the paper information. In other words, compared to conventional methods, the present invention makes it possible for users to easily and accurately manage the design information of more steel frame products and parts, and furthermore, to use the design information to appropriately and efficiently manage the manufacture of steel frame products and parts. By appropriately and efficiently managing the manufacture of steel frame products and parts, it is expected that there will be effects such as improving the efficiency of the manufacture of steel frame products and parts and preventing delivery delays.

The server 20 further includes a reception unit 212 that receives input of progress information related to the manufacturing status of steel frame products and parts, and the generation unit 213 generates a list by associating the progress information received by the reception unit 212 with the steel frame products or parts, and the output unit 214 can output the list. This makes it possible to manage information related to the manufacturing progress of steel frame products and parts, which was previously managed by an analog method of printing out design information of the steel frame products or parts on paper and writing the manufacturing progress on the paper, by digital means using a network or computer. In other words, compared to the conventional management method, the present invention makes it possible for users to easily and efficiently manage information related to the progress of steel frame products and parts. This can provide effects such as, for example, improved manufacturing efficiency and prevention of delivery delays. In addition, it is also easy to share the progress information output together with the list with multiple people, and for example, by sharing the list with people other than the person in charge at the manufacturing site, the management of the manufacturing of steel frame products and parts can be made more reliable. It is also possible to share progress with customers, so it can be used to explain progress to them.

The generating unit 213 can also generate a list using different expressions for each progress status of the manufacturing of a steel product or part. By generating a list using different expressions for each progress status, the progress status of each steel product or part listed on the list can be visually communicated to the user in an easy-to-understand manner. It also becomes possible to easily compare the manufacturing progress status of each steel product and part, making it easy for the user to identify, for example, steel products or parts whose manufacturing is delayed.

The reception unit 212 can also receive the progress status of the installation of joints, which are components, as progress information regarding the manufacturing status of steel frame products. The installation of joints in columns, which are steel frame products, involves many processes, such as assembling the joints, robot welding, temporary attachment of parts including the joints, actual welding, UT, and acceptance inspection. Therefore, it was complicated to grasp the progress status of joint installation using the conventional paper-based manufacturing management method, but by having the reception unit 212 receive progress information on these processes related to joint installation and having the information listed by the generation unit 213, it becomes possible to easily manage the progress status of columns, including the installation of joints.

The acquisition unit 211 can also acquire design information by acquiring and analyzing three-dimensional design data generated by three-dimensional computer-aided design software. By acquiring and analyzing the three-dimensional design data and acquiring it as design information, it becomes possible to perform manufacturing management that includes three-dimensional design information, which was not possible with conventional paper-based management. By including three-dimensional design information, users can more easily and accurately manufacture steel products and parts.

The generating unit 213 also generates an image showing a steel frame product or part based on the design information, and the output unit 214 can output an image showing the steel frame product or part in association with each steel frame product or part in the list. This makes it possible to confirm the shape, etc. of the steel frame product or part listed in the list by image, so that the user can more easily and accurately grasp the shape of the steel frame product or part.

The manufacturing management device may further include a drawing display unit 215 that displays the steel frame product or part in association with a drawing of the building to be constructed using the product. By including the drawing display unit 215, the user can easily understand which part of the building (steel frame) the steel frame product or part will be used in.

The drawing display unit 215 may also display the progress of the manufacture of steel frame products and parts in association with the architectural drawings of the building in which the steel frame products and parts are used. This allows the user to visually grasp not only the progress of individual steel frame products and parts, but also the overall manufacturing progress of the required steel frame products and parts.

The server 20 can receive information regarding the priority of the manufacturing of steel products or parts, separately from information regarding the progress of the manufacturing of the steel products or parts, via the ranking unit 216. This allows the information regarding the priority to be reflected in the list generated by the generation unit 213, so that the user can easily understand the priority of the manufacturing of each steel product or part.

The server 20 can notify the user of progress information regarding the manufacturing status of steel products or parts via the notification unit 217. This allows the manufacturing status to be more reliably communicated to the user, so that effects such as improved manufacturing efficiency and prevention of delivery delays can be more reliably achieved.

The server 20 can display a warning using the warning display unit 218 if an abnormality occurs in the progress of the manufacturing of steel products or parts. This can prevent mistakes such as not manufacturing what should be manufactured, or shortages due to an insufficient delivery quantity. As a result, it can help to more reliably deliver the steel products that should be delivered.

The present invention is not limited to the first embodiment described above, but may be modified in various ways within the scope of the claims.

For example, in the first embodiment described above, an example has been shown in which the acquisition unit 211 acquires design information from the design system 30, but this is not limiting. For example, the server 20 may directly acquire design information that has been stored in advance on a hard disk or in the cloud, without going through the design system 30.

In addition, in the above example, the reception unit 212 receives progress information from the user terminal 10, but the present invention is not limited to this example. For example, the server 20 may directly acquire progress information that has been stored in advance on a hard disk or in the cloud, without going through the user terminal 10. In other words, the server 20 may indirectly receive progress information from the user terminal 10.

In the above-described first embodiment, the list etc. output by the output unit 214 is displayed on the display unit 14 of the user terminal 10 via a network, but the present invention is not limited to this and may be output to a display etc. directly connected to the server 20. The user terminal 10 may be a monitor etc. that is not used by the manufacturing personnel.

In the above first embodiment, an example in which the server 20 is configured as a single independent device has been described, but the configuration of the device is not limited to this. The server 20 may be configured as being composed of multiple devices, or may be configured as being included in a device having other functions. For example, the server 20 may be configured in a distributed manner on a cloud server composed of a large number of servers. Alternatively, an application that realizes the functions of the server 20 may be installed on the user terminal 10, and the processing of the server 20 may be executed on the user terminal 10.

In the above first embodiment, the user terminal 10 has been described as a smartphone or tablet terminal carried by the user, but the embodiment of the user terminal 10 is not limited to this. The user terminal 10 may be, for example, a wearable terminal such as a glasses-type information terminal worn on the user's head or a wristband-type information terminal worn on the arm, or may be an embedded information terminal embedded in the user's body.

The processing units in the flowchart in the above-described first embodiment are divided according to the main processing content in order to make it easier to understand the processing of the server 20. The method of classifying the processing steps and the order of the processing do not limit the present invention. The processing performed in the server 20 can also be divided into more processing steps. Furthermore, one processing step may execute more processes, and the order of each processing step may differ from that in the flowchart in the first embodiment.

The means and methods for performing various processes in the system according to the first embodiment described above can be realized by either a dedicated hardware circuit or a programmed computer. The above program may be provided by a computer-readable recording medium such as a flexible disk or CD-ROM, or may be provided online via a network such as the Internet. In this case, the program recorded on the computer-readable recording medium is usually transferred to and stored in a storage unit such as a hard disk. The above program may also be provided as standalone application software, or may be incorporated into the software of the device as one function of the system.

Second Embodiment
Next, a second embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, this embodiment is also an example, and the present invention is not limited to this embodiment.
FIG. 14 is a diagram for explaining an example of the range in which the manufacturing management device according to the second embodiment of the present invention manages the progress status of the manufacturing of a steel frame product.
The range of management shown in Fig. 14 is made possible by the system whose schematic configuration is shown in Fig. 1. Therefore, the second embodiment is also premised on the use of that system.

The made-to-order manufacturing company 500 is a company that receives orders from clients for the manufacture of steel frames for buildings, designs the steel frames, and manufactures and delivers each part that makes up the steel frames as steel frame products 535. To this end, the made-to-order manufacturing company 500 has a design department 510, an ordering department 520, a manufacturing department 530, a painting department 540, and a shipping department 550.

The design department 510 is a department that designs the steel frame of the building. The results of this design are input to the server 20 in the form of various files, as described below, and are used to manage the progress of the manufacturing of the steel frame product 535. The dashed arrows in FIG. 14 represent the relationship of input and output of information with the server 20. The dashed arrows other than those of the design department 510 and the ordering department 520 include the input and output of information for progress management.

Progress management refers to identifying the manufacturing progress of the steel product 535, converting it into data, and making it possible to visualize the progress. This progress management is realized by an order/progress management function 41 installed in the server 20. A management result presentation function 42 is a function that visually presents the data generated by progress management. Each of the screens shown as examples in Figures 5 to 9 is displayed on the user terminal 10 by this management result presentation function 42. Note that the order/progress management function 41 and the management result presentation function 42 correspond to the functions that realize the progress update unit and screen generation unit in the second embodiment, respectively.

Many parts are usually used to manufacture a steel frame product 535. If the necessary parts have not been manufactured, it is impossible to manufacture the steel frame product 535. Furthermore, one or more parts are required to manufacture a part, and if the parts have not been manufactured, it is impossible to manufacture the part. For this reason, as shown in Figures 5 and 6, progress management is performed not only at the steel frame product 535 level, but also at the part and part level.

Here, parts are a general term for items used in the manufacture of steel products, and parts may be components. Also, parts are a general term for items used in the manufacture of components, and other components may be used as components. Unless otherwise specified, the terms steel products, parts, and components are used in this sense. The simplest component is steel delivered by a steel distributor 610, or a part of that steel.

The ordering department 520 reviews the design results and places an order to purchase the necessary materials, including steel. It places an order with the steel distributor 610 for the amount of steel required to manufacture the steel product 535. Meanwhile, the ordering department 520 decides which steel products should be outsourced to the outsourcing company 620, and requests the outsourcing company 620 to manufacture the decided steel products. To do this, the ordering department 520 requests the steel distributor 610 to deliver the steel, dividing it into its own portion and the portion for the outsourcing company 620.

Information representing the steel material order details is registered in server 20. Server 20 then manages the progress of the steel product manufacturing, including the delivery (carry-in) of the ordered steel material. As a result, server 20 manages the progress from ordering the steel material to shipping the steel product.

The outsourcing company 620 uses the steel delivered by the steel distributor 610 to manufacture the steel products requested by the order-receiving manufacturer 500, and delivers the manufactured steel products to the order-receiving manufacturer 500 as delivered products 625. The progress management of the manufacture of the delivered products 625 at the outsourcing company 620 is also performed by the server 20. As a result, the network shown in FIG. 1 is connectable to the user terminals 10 used by the outsourcing company 620, and enables communication between the server 20 and each user terminal 10 used by the outsourcing company 620. Note that the outsourcing company 620 does not have to be a single company.

The manufacturing department 530 is a department that manufactures steel products 535 in one or more processing and assembly factories 531. The inspection department 532 in the manufacturing department 530 is a department that inspects the manufactured steel products 535 to confirm whether they are appropriate or not. UT is performed by this inspection department 532. As a result, only the steel products 535 that are confirmed to be appropriate are passed on to the painting department 540, where the steel products 535 are painted or plated. The shipping department 550 ships the painted or plated steel products 535. Hereinafter, the symbol 535 is used only on steel products that have been completed in the processing and assembly factories 531, to distinguish them from steel products before or during production.

The dashed arrows indicate not only the design department 510 and manufacturing department 530, but also the ordering department 520, painting department 540, and shipping department 550. Therefore, the process for identifying the progress of a steel product whose manufacturing has begun includes not only each manufacturing process of the steel product in the manufacturing department 530, but also the painting process after manufacturing is completed and the shipping process. At the made-to-order manufacturing company 500, the server 20, which is the manufacturing management device according to the second embodiment, covers these departments, manages the progress of the manufacturing of the steel product, and presents the management results as necessary via the user terminal 10. This is the same for the outsourcing company 620, so the explanation will focus only on the made-to-order manufacturing company 500.

The user terminal 10 can be used to send information for progress management. To send a progress processing request that includes this information, it is necessary to specify the steel product or part whose progress is changing. This specification is made by selecting from a list of the steel product or part to be manufactured, or by reading a medium attached to the steel product or part. This specification makes it possible to send to the server 20 a progress processing request that includes a code (see FIG. 6, etc.) that is identification information for the steel product, part, or member whose progress is changing. The medium is, for example, a printed medium on which a two-dimensional code or the like is formed, or an IC tag.

Upon receiving a progress processing request, the server 20 updates the manufacturing progress of the steel product, part, or component specified by the code. This update allows a worker using the user terminal 10 to check the progress of any steel product, any part, or any component. Because such progress updates can be performed using the user terminal 10, it is possible to update the progress in real time and also to check the current situation. Overall, the burden on workers for updating the progress is distributed, and inappropriate updates to the progress can be avoided. As a result, it becomes possible to properly and efficiently manage the manufacturing of steel products in real time.

FIG. 15 is a block diagram showing an example of a functional configuration realized on a manufacturing management device according to the second embodiment.
In the second embodiment, the schematic configuration of the server 20, which is a manufacturing management device, is the same as that in the first embodiment, that is, as shown in Fig. 3. Therefore, the functional configuration shown in Fig. 15 is based on the schematic configuration shown in Fig. 3. This also applies to the user terminal 10 and the design system 30.

As shown in FIG. 15, in the second embodiment, the control unit 21 has, as functional components, a setting unit 701, a file registration unit 702, an authentication unit 703, an order processing unit 704, a progress processing unit 705, a position identification unit 706, a production volume calculation unit 707, a processing cost calculation unit 708, and a page generation unit 709. The memory unit 22 has an employee information storage unit 801, a detail file storage unit 802, and a processing drawing file storage unit 803. Each of the units 701 to 709 on the control unit 21 is realized by the control unit 21 executing an application program developed to realize the order/progress management function 41 and the management result presentation function 42 on the server 20. This application program corresponds to the manufacturing management program in the second embodiment.

The setting unit 701 enables the setting, registration, and editing of various information. One type of information that can be registered is employee information. This employee information is management information that includes various information such as name, employee ID, assigned department, location, manufacturing process in charge, authentication ID, authentication password, and qualifications held. An employee information storage unit 801 is secured on the memory unit 22 for storing employee information.

The ID and password are used for authentication to use the server 20. To access the server 20 using the user terminal 10, authentication by inputting the ID and password is required. This allows the employee in charge to use any tablet, smartphone, etc. as the user terminal 10.

The file registration unit 702 corresponds to the registration of various files including various specification files and various processing drawing files.
Detail files are files created for each steel material, each part, and each steel product according to the steel design. Usually, multiple detail files are created for each steel material, each part, and each steel product. At least the first, second, and third storage areas are logically reserved for each detail file.

The first storage area stores an image in which details such as name, processing content, shape, weight, quantity, and material are organized in table format by type. In this case, type refers to, for example, parts that are made from the same type of steel, but have differences in the type of processing to be performed or the processing locations. In other words, type here refers to a subcategory that is further down the classification of parts that are generally considered to be the same type.

The second storage area stores detailed information organized by type. Each piece of information such as material and size shown as items in Figure 5 is information extracted from the detailed information stored in the second storage area. The third storage area stores information representing items whose production has been completed among those for which detailed information is stored. This information is, for example, information extracted from the detailed information (extracted detailed information) plus information such as the name of the person in charge, the completion date and time, and the production location.

By storing such information in the third storage area, it becomes possible to identify the manufacturing progress at the part level, including steel. For this reason, the information stored in the third storage area will hereafter be referred to as "progress status information." Progress status information is generated when a progress processing request is received.

By registering such detail files, progress management can be performed at each level for materials, parts, and steel products. A storage location for progress information is automatically secured, and related information is consolidated on a detail file basis. This not only makes it easier to handle information for progress management, but also makes it easier to check the content of the progress information.

A processing drawing file is a file that stores drawings that explain the processing details and assembly methods of steel frame products or parts. For this reason, processing drawing files are also created for each steel frame product and each part depending on the steel frame design. The image of the column shown as a pop-up in Figure 8 is a processing drawing stored in a processing drawing file. To enable the display of such processing drawings, a code is entered in each processing drawing file in an identifiable manner, or the file is associated with a code.

Another file to be registered is a floorplan file in which a floorplan is stored as an image. Figure 9 shows an example of a floorplan stored in a floorplan file.
In the memory unit 22, a detail file storage unit 802 is provided for storing detail files, and a processing drawing file storage unit 803 is provided for storing processing drawing files. In the detail file storage unit 802 and the processing drawing file storage unit 803, the detail files and processing drawing files are stored separately for each building. A floor plan file is treated as one of the processing drawing files.

The registration of various files is performed on a details registration screen, which is a page generated by the page generating unit 709. Figures 16 and 17 are diagrams for explaining an example of the details registration screen.
As shown in Figures 16 and 17, the detail registration screen has a display area 910 in which a side menu is arranged, and a display area 920 in which file designation areas 921 to 925 for designating various files to be registered are arranged. The detail registration screen 920 can be displayed by clicking "original size" in the side menu. In addition, a designation area for designating a building is also provided in this display area 920.

The die DXF file designation area 921 is an area for registering a die processing drawing file in DXF format. In this designation area 921, a text box 931 for inputting a page top addition number and a "Select file" button 932 are arranged.
The page top addition number is identification information assigned to the first page of various files to be registered. The display of the processing drawing file is managed by the page number specified here. The page here is, for example, a virtual one. The "Select File" button 932 makes it possible to select a file stored in any storage location. The dice are parts used in manufacturing joints.

The joint and pillar production detail file designation area 922 is an area for registering detail files for each part related to the manufacture of pillars, such as dice, joints, and pillars. This file designation area 922 has multiple text boxes 931, multiple check boxes 933, and one "Select file" button 932.

The various detailed files are used to extract information to be displayed in various lists. To allow this information to be extracted appropriately, multiple text boxes 931 and multiple check boxes 933 are provided for various specifications. More specifically, the multiple text boxes 931 are used to input character strings for recognizing the position of the title, the arrangement order of the titles, symbols representing blankets that should be ignored, symbols representing blankets that should not be ignored, and the like. As is clear from this, the contents of the file to be registered are confirmed, and the parts that make up the pillars, the materials that make up those parts, etc. are also considered to be manufacturing objects. Such manufacturing objects can be confirmed by the registered processing drawing file.

The first format specification file designation area 923 and the second format specification file designation area 924 are both areas for registering specification files for each part that are not the subject of the file designation area 922. Both file designation areas 923, 924 contain a combo box 935 with a button 935a for displaying a list box, and a "Select file" button 932. This allows the user to select the part name that corresponds to the specification file to be registered from the part names arranged in the list box in these file designation areas 923, 924.

The target detailed file formats differ between these file designation areas 923 and 924. As a result, the worker selects one of these file designation areas 923 and 924 depending on the detailed file format, and specifies (selects) the detailed file to be registered and registers it.

After deciding which steel materials to order, the ordering department 520 creates a detail file. This detail file can also be registered from the detail registration screen. However, ordered steel materials are different from parts, and it is only necessary to manage whether or not they have been delivered. For this reason, the detail files created by the ordering department 520 not only differ in file structure from those created by the design department 510, but are also handled differently in terms of progress management. For example, the handling can be done by inputting whether or not the steel materials represented in the detail file have been delivered.

The floor plan file designation area 925 is an area for registering a floor plan file that stores a floor plan as an image, such as the example shown in FIG. 9. In this file designation area 925, only the "Select file" button 932 is located.

FIG. 18 is a diagram illustrating an example of the registration confirmation screen.
This registration confirmation screen makes it possible to check the various registered files. A file instructed to be registered on the above-mentioned detail registration screen is actually registered by the instruction to register on this registration confirmation screen. Therefore, this confirmation screen is displayed or can be displayed when the registration of a file is instructed on the detail registration screen. On this confirmation screen, the display area 920 is used to display the contents of the target file among the various registered files. The detail registration screen can be redisplayed by clicking on "Original Size" in the side menu arranged in the display area 910.

At the upper left of the display area 920, a “Register” button 961, a “Display all” button 962, and a “Refine display” button 963 are arranged.
The "Register" button 961 is a button for instructing the registration of a file for which registration has been instructed on the details registration screen.

The "Show all" button 962 and the "Narrowed display" button 963 are both buttons for instructing the display of the contents of the file instructed to be registered. Specifically, the "Show all" button 962 is a button for instructing the display of all the contents (pages) of the file instructed to be registered. The "Narrowed display" button 963 is a button for instructing the display of only the specified contents (pages).

The tabular image 950 is displayed as the contents of the file. This image 950 is stored in the first storage area of the detail file. By storing such an image 950 in the first storage area of each detail file, the person in charge can more easily check the contents of the detail file that he or she has instructed to register.

One or more images 950 in table format are stored in the first storage area of the detail file. Each image 950 is assigned a page number that changes in ascending order from the page number specified as the page start number. A list 940 arranged above the images 950 shows a list of each image 950 that exists in the first storage area of the detail file instructed to be registered. For this reason, each row has a check box, an assigned page number, and various information represented by the image 950. As a result, the "narrowed display" button 963 is used to instruct the display of only the images 950 that correspond to the page specified by checking the check box. The "display all" button 962 is used to instruct the display of images 950 on all pages.

In this way, in the second embodiment, files to be registered are registered by having the person in charge check them again individually. This is because if there is an error in the information for managing progress, it will not be possible to properly manage progress. By having the person in charge check them again, files to be registered can be registered more reliably.

Returning to the explanation of FIG.
The authentication unit 703 responds to an authentication request from the user terminal 10. The authentication request includes an ID and a password. Therefore, the authentication unit 703 performs authentication by checking whether there is employee information having the combination of the ID and password included in the authentication request. This authentication identifies the person in charge who uses the user terminal 10.

The order processing unit 704 handles orders to the subcontractor 620. Specifically, it performs processing to make it possible to identify the steel frame products to be manufactured that have been ordered from the subcontractor 620. This processing makes it possible to check the manufacturing progress of the steel frame products to be manufactured by the company that actually manufactures them.

The progress processing unit 705 processes a progress processing request sent from the user terminal 10. When the progress processing request is received, the progress processing unit 705 identifies the progress status of the steel frame product, parts, or components, and generates and stores progress status information to be stored in the target detail file. When a progress processing request is sent from the painting department 540 or the shipping department 550, the progress processing unit 705 stores the generated progress status information by adding it to the corresponding steel frame product detail file. At this time, the stored progress status information may be information including, for example, the process name, the person in charge, and the end date and time. The inspection department 532 associates the code with the inspection results by the UT or the like and stores them separately in the memory unit 22 as progress status information. The inspection results are input by the person in charge on a page for inputting inspection results.

There may be parts and components that require work in multiple manufacturing processes to be manufactured. In such cases, the progress status information generated for each manufacturing process is saved in the third storage area of the same detailed file. As a result, it is possible to display a list such as the example shown in Figure 7. As is clear from this, the progress status information also represents the history of the manufacturing processes that were performed in manufacturing the manufacturing object.

The location identification unit 706 identifies the location of the user terminal 10 that sent the progress processing request. As described above, the person in charge of using the user terminal 10 is identified by authentication. Information indicating the location of the person in charge is included in the employee information. From this, the location identification unit 706 identifies the person in charge of using the user terminal 10 that sent the progress processing request, and by referring to the employee information of the identified person, identifies the location indicated by the employee information as the location of the user terminal 10. The location information indicating the identified location is saved as part of the progress status information. This location information corresponds to the location information in the second embodiment. Note that the location of the user terminal 10 may be identified by having the user terminal 10 transmit location information. The location information is not particularly limited, but may be, for example, information obtained by a satellite positioning system, information indicating an access point with which the user terminal 10 communicates, or the like.

The output calculation unit 707 calculates the output, which is statistical information related to the manufacturing of steel products, under specified conditions. The conditions are specified on a dedicated page. The example shown in FIG. 7 is an example of a page on which the calculation results by the output calculation unit 707 are displayed. The generation of various pages, including this page, a page for specifying conditions, and a page for inputting UT inspection results, is performed by the page generation unit 709 and transmitted via the communication unit 23.

The processing cost calculation unit 708 calculates the processing cost required for the specified type of processing of the specified portion. The calculated processing cost can be said to be an index representing the load, the amount of work, or the required manufacturing capacity in manufacturing a steel frame product. For this reason, in the second embodiment, the processing cost can be calculated as useful information in terms of being able to support the decision of the steel frame product to be requested to be manufactured by the outsourcing company 620.
The designation of the part, etc. is performed on a dedicated page (screen) generated by the page generation unit 709. On that page, the type of processing to be performed, the unit price, etc. may also be designated. Here, it is assumed that these designations are also possible.

The page generation unit 709 generates various screens to be displayed on the user terminal 10 as pages. To generate the pages, the progress status information generated and stored by the progress processing unit 705, the position identification result by the position identification unit 706, the output calculated by the output calculation unit 707, and the processing cost calculated by the processing cost calculation unit 708 are used as necessary. Here, the contents displayed on each of the various screens and the method of generating the screens will be specifically described with reference to the various screens, examples of which are shown in Figures 19 to 22.

FIG. 19 is a diagram illustrating an example of a live display screen.
This actual status display screen is a list of manufacturing processes in which the items to be inspected are produced, in which the manufacturing processes in which work has been completed are arranged in order of the end date and time. In the example shown in Fig. 19, the information on the manufacturing processes is arranged in descending order, with the manufacturing process with the latest end date and time, in other words, the manufacturing process with the shortest time between the end date and the current date and time, being placed at the top. As information on the manufacturing process, information on each of the items of location, part, code, process, person in charge, and object name, in addition to the end date and time, is shown.

Below each item name is a text box or combo box. Each text box and combo box is used to narrow down the manufacturing processes that are being displayed. Therefore, workers can narrow down the manufacturing processes that are being displayed by entering information into one or more text boxes or combo boxes.

The inspection is carried out by workers (hereinafter referred to as "inspectors" to distinguish them from other workers) assigned to the inspection department 532. For this reason, the live display screen that allows for filtering is also expected to be viewed by inspectors. It is expected that the user terminal 10 on which the screen will be displayed will be a user terminal 10 that is installed as a monitor in a place where an inspector is waiting for the next inspection, and that the screen will be displayed continuously.

By displaying the actual status display screen on the user terminal 10 placed in such a location, the inspector can carry out a more rapid inspection when an item requiring inspection occurs. More specifically, the inspector can move more quickly to the location where the item requiring inspection occurs. As a result, the average time from when an item requiring inspection occurs to when the inspection is completed can be shortened, so the average downtime during which production is stopped for inspection is also shortened, and the production of the steel product 535 can be carried out more quickly. In addition, since the inspector can recognize the occurrence of an item requiring inspection by checking the actual status display screen displayed on the user terminal 10, there is basically no need for the inspector to move to check whether an item requiring inspection has occurred. This has the advantage of improving the work efficiency of the inspector.

The location placed on the live display screen is the location identified by the location identification unit 706. The location identification unit 706 enables the inspector to move more quickly to the location where he or she needs to go. This location identification unit 706 also enables management focusing on the manufacturing location of steel products and parts, etc., and the presentation of various information including the volume of work completed. This is shown in Figure 21, which will be described later.

Items that need to be inspected arise from time to time. For this reason, if there is a user terminal 10 displaying a live display screen, the page generation unit 709 monitors the progress status information stored in each detailed file and identifies newly stored progress status information. If there is identified progress status information, the page generation unit 709 checks whether an item that needs to be inspected has arisen in the manufacturing process whose end is indicated by the progress status information. In this way, if it is confirmed that the work in the manufacturing process in which the item that needs to be inspected has been completed, the page generation unit 709 generates a live display screen in which the new manufacturing process has been added to the list, and transmits the newly generated live display screen via the communication unit 23.

Meanwhile, the page generation unit 709 checks whether the manufacturing process whose identified progress status information indicates completion is an inspection process. When the inspection process ends, inspection of the inspected object becomes unnecessary. For this reason, the page generation unit 709 deletes the manufacturing process that produced the inspected object from the list, or generates a current status display screen with a changed display form, and transmits the newly generated current status display screen via the communication unit 23. Note that the order in which the manufacturing processes are updated when arranging the information may be the opposite to that shown in FIG. 19.

FIG. 20 is a diagram illustrating an example of a construction date warning display screen.
There is a delivery date for each steel frame product delivered by the made-to-order manufacturing company 500. The delivery date depends on the construction date when the steel frame product is assembled on-site. For this reason, a construction date is set as the delivery date for each steel frame product. The construction date warning display screen is a list in which the construction date and information related to the steel frame product are arranged for each object, in order from the object with the shortest time until the construction date, that is, the object with the least time until the delivery date. The information items related to the steel frame product are, from the left in FIG. 20, the work area, the code, and the main material. The construction date is arranged further to the right of that, that is, at the very right.
The three pieces of information for one steel structure product and the construction date are arranged on each line under the object name, so that each line of information represents one steel structure product and its construction date.

The construction date and the setting time, which will be described later, are both set by the setting unit 701 and are information stored, for example, in a storage area (not shown) secured in the memory unit 22. The progress of production, including shipment for delivery, can be identified by referring to the progress information. For this reason, the construction warning display screen is designed to arrange information on each steel product in a display form according to the progress. Since shipped steel products 535 are not included, the steel products that are basically the subject of arrangement are those that have not yet been shipped or those whose production has not yet been completed.

As shown in FIG. 20, for steel products with less time until construction than the set time, information is displayed in multiple display formats. Only the symbol is displayed in a different display format. This is to allow the current progress of the steel product to be confirmed in addition to the warning that the time until construction is less than the set time. The difference in display format is indicated by shading. From this, FIG. 20 shows that a warning is being issued for the steel product whose information is arranged in the top four rows of the column displaying "△△△ Logistics Center" as the property name. The warning display screen may focus on setting information other than the construction date. The warning display screen may focus on, for example, a manufacturing deadline date set separately from the construction date. The display format indicated by shading may be different for, for example, primary processing completed, secondary processing completed, and welding completed.

The construction date warning display screen is generated for each property by referencing the construction date, current date and time, and progress status information set for each steel product. As time passes, the progress status of each steel product 535 changes. The construction date may also be changed. For this reason, the page generation unit 709 generates a construction date warning display screen as necessary if there is a user terminal 10 that is displaying the construction date warning display screen, just like the live display screen, and transmits the generated display screen to the user terminal 10.

Such an erection date warning display screen is also intended to be viewed by people in a position to manage the manufacturing of steel frame products. This is because such people can take action, such as changing how the manufacturing department 530 uses its resources, depending on the current or predicted future situation. In other words, by making the user aware of the current situation, it becomes relatively easy to take desirable action at an earlier stage, which helps to achieve higher quality in managing the manufacturing of steel frame products. In order to more reliably achieve such higher quality, it is desirable to provide a user terminal 10 that constantly displays the erection warning display screen.

FIG. 21 is a diagram for explaining an example of a factory-by-factory production volume graph display screen.
This factory-specific production volume graph display screen is one of the production volume display screens, and like the other example shown in Fig. 7, it is generated according to the conditions specified on the page (screen) for specifying the conditions. In the case of this factory-specific production volume graph screen, the conditions include the target period for calculating the production volume, the unit period for calculating the production volume by day, the total weight (accumulated value) of the steel products 635 as the type of production volume, each factory as the target for calculating the production volume, and a graph (bar graph) as the display form of the production volume. As a result, on this graph display screen, the total weight of the steel products 535 manufactured at each factory during the target period is shown by a bar graph by day. The unit of the vertical axis is t (tons).

When such conditions are specified, the production volume calculation unit 707 calculates the total weight of the steel products 535 manufactured during the target period by tallying them up by factory. The page generation unit 709 then uses the calculation results to generate a production volume by factory graph display screen, an example of which is shown in FIG. 21. The generated display screen is transmitted via the communication unit 23 to the user terminal 10 to which it should be sent.

As described above, the progress status information includes location information, information indicating the end date and time, etc. The progress status information also includes information indicating the weight of the steel products 535 (see FIG. 18). Based on this, the output calculation unit 707 refers to the progress status information for which production was completed within the target period, and calculates the total weight of the steel products 535 produced within the target period by factory and by day.

In the list shown in FIG. 7, the output calculation unit 707 calculates the output in a similar manner. The page generation unit 709 then uses the calculation results to generate the list. However, when generating a list such as that shown in FIG. 7, the output calculation unit 707 refers to the information stored in the second and third areas of the required detail file to calculate the total number of units by part, and calculates the total number of units for which processing has been completed by processing type. As a result, the page generation unit 709 uses the calculation results of the output calculation unit 707 to generate a list such as that shown in FIG. 7.

The output displayed on the output display screen as shown in Figures 7 and 21 not only allows you to check the current situation, but is also useful information for checking various manufacturing results. The output displayed as in the example shown in Figure 21 is also useful for determining whether an order for a project can be accepted, identifying factories with lower processing capabilities compared to others, and so on. This is expected to support the acceptance of orders for projects, manufacturing plans for steel products, and the identification of areas for improvement in each factory.

The volume-related screens that can be generated are not limited to those shown in FIG. 7, FIG. 21, and their types. The conditions for calculating volume can be specified in order to make it easier to perform various checks or reviews by allowing the desired screen to be displayed as desired, thereby realizing greater convenience. Display formats include tables in addition to graphs. Even just for graphs, there are multiple types that can be specified.

FIG. 22 is a diagram illustrating an example of the subcontract quotation table screen.
This outsourcing quotation table screen is a screen that shows the cost required for welding the specified parts as processing costs for each steel product (delivered product) on the assumption that the manufacturing of the specified parts is requested to the outsourcing company 620. It is one of the quotation display screens. For this reason, it is assumed that it will be viewed mainly by workers assigned to the ordering department 520. The page generation unit 709 generates this quotation table screen using the calculation results of the processing costs by the processing cost calculation unit 708.

As shown in Figure 22, this screen shows the item names of information related to steel products, such as work area, code, number, part, size, page, total length, total weight, sleeve 1 to sleeve 4, notch, full penetration weld length, partial penetration weld length, amount (yen), and others. In the total item, at least the accumulated number of units, accumulated total weight, accumulated full penetration weld length, partial penetration weld length, and accumulated amount are shown. The weld length is divided by type of welding because the unit price differs depending on the type of welding. The unit of welding length is m (meter).

In calculating the processing cost, in addition to specifying the processing method, i.e., the type of processing, the part is also specified. "Beam" representing the part in Fig. 22 is the name of the specified part. In addition to the name, the page, code, etc. can be used to specify the part, in other words, to select the specified object.
In the information whose item names are shown in Fig. 22, all the information of the item names except for, for example, the full penetration weld length, the partial penetration weld length, and the amount are information that can be extracted from the second storage area of any of the detail files related to the specified part, or can be generated using the extracted information. The accumulated value of the total weight is calculated by accumulating the total weight extracted for each steel frame product.

The full penetration weld length and partial penetration weld length are cumulative values of the weld lengths in each welding operation performed in the manufacture of a steel frame product. Therefore, when a part containing multiple members is used in the manufacture of a steel frame product, the weld length by type includes the length welded in the welding operation of each part. The weld length required for the manufacture of each part and the weld length required for the integration of the parts are obtained as information from, for example, software introduced to the design department 510 for steel frame design, or a database used by that software. For the sake of convenience, it is assumed here that the weld length is obtained from the database. The storage device in which the database is constructed may be accessible by the server 20. For this reason, a detailed explanation of the location of the storage device, the method of accessing the storage device, etc. is omitted. In other words, it is assumed that the server 20 can directly obtain the necessary information from the database. Each weld length corresponds to weld length information, which is one of the processing information.

By collecting such information, the processing cost calculation unit 708 calculates each weld length for each steel frame product and calculates the cumulative value of each calculated weld length. Note that the required weld length may be stored as information in the second storage area of each detailed file.
The unit price, which varies depending on the type of welding, may need to be changed depending on the circumstances at the time of ordering. For this reason, each unit price is set as a calculation condition for calculating the additional value. As a result, each amount is calculated by multiplying the calculated weld length by the unit price. The part is set as an extraction condition that specifies the part for which the additional value is to be calculated.

In the manufacture of steel frame products, the amount of steel frame products that can be manufactured depends heavily on the type of processing to be performed and the amount of each type of processing. In particular, welding, which joins and integrates multiple metals, often requires a very long work time, unlike other processing methods. For this reason, welding is the main processing method used in the manufacture of steel frame products, and is a processing method that should be given special importance when considering the manufacturing load. As a result, both the accumulated value of each weld length and the accumulated value of the amount are useful indicators for appropriately predicting the manufacturing load of steel frame products. Due to this usefulness, welding is the most important processing method for calculating processing costs. For this reason, welding is positioned as a required processing method, and is excluded from the processing methods that can be specified.

As shown in FIG. 14, the made-to-order manufacturing company 500, which is considering outsourcing at least a portion of the steel products to be manufactured to an outsourcing company 620, needs to take into account the manufacturing capacity of the outsourcing company 620. As described above, the outsourcing quotation display screen as shown in FIG. 22 displays information that is useful for appropriately predicting the manufacturing load of steel products. Therefore, by generating and displaying this display screen, it is possible to support the made-to-order manufacturing company 500 in placing appropriate orders with the outsourcing company 620. For this reason, it is assumed that the screen will be viewed primarily by workers assigned to the ordering department 520.

As shown in FIG. 14, an order/progress management function 41 and a management result presentation function 42 are implemented on the server 20. When the functional components shown in FIG. 15 are implemented on the control unit 21, the order/progress management function 41 is provided by each unit 701-706 and 709, excluding the output calculation unit 707 and the processing cost calculation unit 708. In a narrow sense, it is provided by the order processing unit 704, the progress processing unit 705, and the page generation unit 709. The management result presentation function 42 is provided by the output calculation unit 707, the processing cost calculation unit 708, and the page generation unit 709.

Figures 23 and 24 are flowcharts showing an example of the overall process executed by a control unit installed in a server, which is an information processing device according to the second embodiment. This overall process is mainly executed by the server 20 in order to respond to various requests from the user terminal 10. It is realized by the control unit 21 executing application programs developed to realize an order/progress management function 41 and a management result presentation function 42 on the server 20. Next, this overall process will be described in detail with reference to Figures 23 and 24. It is assumed that the control unit 21 is the entity that executes the process.

First, in S401, the control unit 21 determines whether or not a setting request related to settings has been received from the user terminal 10. This setting request is a request sent in response to an instruction from an operator to register information input on one of the various setting screens, and the input information and the operation content using that information are also sent.

When the communication unit 23 receives a setting request sent from any of the user terminals 10, the determination in S401 becomes YES and the process proceeds to S402. In S402, the control unit 21 executes a setting process to save the input information according to the operation content. After executing this setting process, the process returns to the above S401. Execution of this setting process makes it possible to register and edit employee information, set the construction date, or change the set construction date, etc.

On the other hand, if no setting request is received from any of the user terminals 10, the determination in S401 becomes NO and the process proceeds to S402. In S402, the control unit 21 determines whether or not a registration request has been received from the user terminal 10. This registration request is made to register a file selected on the detail registration screen, an example of which is shown in FIG. 16 and FIG. 17, and the selected file and its type, etc. are also transmitted.

If the communication unit 23 receives this registration request from any of the user terminals 10, the determination in S402 becomes YES and the process proceeds to S404. In S404, the control unit 21 executes a registration process to store the transmitted file in either the detailed file storage unit 802 or the processing drawing file storage unit 803 depending on the type of the file. After the execution of this registration process, the process returns to the above S401.

As described above, various files are registered individually. When the registration of one file is instructed on the detail registration screen, that file is ultimately registered by the registration instruction on the detail confirmation screen. For this reason, the registration process of S404 is shown as also corresponding to the generation and transmission of the detail confirmation screen, and instructions other than the registration instruction on the detail confirmation screen.

On the other hand, if the communication unit 23 does not receive a registration request from any of the user terminals 10, the determination in S403 becomes NO and the process proceeds to S405. In S405, the control unit 21 determines whether or not a login request has been received. As described above, this login request is a request to enable use of the server 20 via the user terminal 10, and an authentication ID and password are also sent.

When the communication unit 23 receives a login request sent from any of the user terminals 10, the determination in S405 becomes YES and the process proceeds to S406. In S406, the control unit 21 executes an authentication process to confirm the presence or absence of employee information having the ID and password pair included in the login request. In S407 after the execution of the authentication process, the control unit 21 transmits the authentication result to the user terminal 10 that received the login request. After this transmission, the process returns to S401. Note that in the authentication process, if the presence of employee information having the ID and password pair can be confirmed, the user terminal 10 is associated with the worker who is the employee using it.

On the other hand, if no login request is received from any of the user terminals 10, the determination in S405 becomes NO and the process proceeds to S408. In S408, the control unit 21 determines whether or not a request to send a page (screen) has been received from the user terminal 10. This request to send is a request that enables the display of a screen specified by the worker, and includes a URL (Uniform Resource Locator) that specifies the screen. Various screens, including the examples shown in Figures 5 to 9 and 16 to 22, are sent from the server 20 to the user terminal 10 in response to this request to be displayed.

When the communication unit 23 receives a transmission request transmitted from one of the user terminals 10, the determination in S408 becomes YES and the process proceeds to S409. In S409, the control unit 21 determines whether the screen specified by the transmission request is the quotation table screen. If the quotation table screen has been specified, the determination in S409 becomes YES and the process proceeds to S421 in FIG. 24. If a screen other than the quotation table screen has been specified, the determination in S409 becomes NO and the process proceeds to S410. In S410, the control unit 21 generates the screen specified in the transmission request and transmits it to the user terminal 10.

If no transmission request is received from any of the user terminals 10, the determination in S408 becomes NO and the process proceeds to S411. In S411, the control unit 21 determines whether or not a progress processing request has been received from the user terminal 10. As described above, this progress processing request is a request for processing to change (update) the progress status of the specified steel product or part, and this progress processing request includes at least the code assigned to the steel product, part, or member.

If the communication unit 23 receives a progress processing request sent from any of the user terminals 10, the determination in S411 becomes YES and the process proceeds to S413. On the other hand, if a progress processing request is not received from any of the user terminals 10, the determination in S411 becomes NO and the process proceeds to S412. In S412, the control unit 21 executes k to respond to other requests from the user terminals 10. After the execution of other processes, the process returns to S401 above.

The employee information storage unit 801 secured in the memory unit 22 stores employee information for all employees. For this reason, other processes may include various processes for managing employees, such as attendance management including overtime hours, reservation management for various facilities, and storage management of daily reports.

In S413, the control unit 21 identifies the worker using the user terminal 10 that caused the progress processing request to be sent as the sender from that user terminal 10. The identified sender is the worker who caused the login request to be sent from that user terminal 10. After identifying the sender, the process proceeds to S414.

In S414, the control unit 21 references the employee information of the worker identified as the sender to identify the sender's name, location, and responsible manufacturing process, etc., and generates progress status information using these identification results, the current date and time, and a code, and registers the generated progress status information. The sender's name is treated as the person in charge, the location as the manufacturing location, the responsible manufacturing process as a completed manufacturing process, and the current date and time as the end date and time. The detail file in which the progress status information is registered is a detail file identified from the responsible manufacturing process and code, and the progress status information is stored in the third storage area of that detail file. After registering the progress status information by storing it, the process returns to S401 above.

In this way, employee information is used to generate progress status information. By using employee information, it is possible to minimize the amount of information to be included in a progress processing request. Reducing the amount of information also reduces the number of operations that must be performed on the user terminal 10. This makes it easier for the person in charge of using the user terminal 10 to operate the user terminal 10, and reduces the burden on them. Progress processing requests can be sent easily.

As described above, when displaying an estimate table display screen such as the subcontract estimate table display screen shown in FIG. 22, it is necessary to specify extraction conditions and calculation conditions. The extraction conditions are the target object, part, processing method, etc. The calculation conditions are the target for which processing costs are calculated, the unit price of the processing work, and the calculation method for the processing costs. The specified extraction conditions and calculation conditions are stored in a transmission request and transmitted to the server 20. From S421 in FIG. 24 onwards, a series of processes are executed to respond to such a transmission request.

In S421, the control unit 21 sets the extraction conditions and calculation conditions according to the extraction conditions and calculation conditions stored in the transmission request. The contents of the calculation conditions set here are the same as or almost the same as the contents of the calculation conditions stored in the transmission request. However, the contents of the extraction conditions are usually larger in information volume than the contents of the extraction conditions stored in the transmission request. This is because it is necessary to obtain necessary information such as weld length from a database, and other information not specified in the extraction conditions may be required depending on the calculation conditions. For example, if a girder is specified as the part and the calculation of the ratio of the weld length of the entire girder to the weld length of the entire beam is specified, information on beams other than the girder will also be extracted.

In S422, which follows S421, the control unit 21 extracts the necessary information according to the set extraction conditions. In the following S423, the control unit 21 performs calculations on the objects of calculation. On the outsourcing quotation display screen, an example of which is shown in FIG. 22, the objects of calculation include the full penetration weld length, partial penetration weld length, and amount for each steel product, and the total includes the accumulated value of the total weight, the accumulated value of the full penetration weld length, the accumulated value of the partial penetration weld length, and the accumulated value of the amount. After the calculations to calculate these are completed, the process moves to S424.

In S424, the control unit 21 generates an estimate table screen (page) on which part of the information extracted in S422 and the calculation results in S423 are arranged. Then, the process proceeds to S425, where the control unit 21 causes the communication unit 23 to transmit the generated estimate table screen to the user terminal 10. After this transmission, the process returns to S401 above.

In the overall processing, as described above, the type of request received from the user terminal 10 is determined, and processing is executed to respond to the received request depending on the result of the determination. As a result, each of the units 701 to 709 shown in FIG. 15 is realized on the control unit 21, making it possible to manage the progress related to the manufacturing of steel products and visualize the results of that management.

When there is a user terminal 10 that displays a screen that needs to be updated from time to time, such as the live display screen shown in FIG. 19, the control unit 21 generates and transmits the screen as needed. The generation and transmission of the screen is performed, for example, by interrupt processing. For this reason, the processing for generating and transmitting the screen is not included in the overall processing.

In the second embodiment, a detailed file is used to save the progress status information, but a separate storage area for saving the progress status information may be reserved, and the progress status information may be stored in the reserved storage area. For this reason, there are no particular limitations on how the progress status information is saved. There are also no particular limitations on the information that constitutes the progress status information. Both of these can be modified in various ways.

When identifying the progress status, since a progress processing request indicates a change in progress status, the manufacturing process that the person in charge of who sent the progress processing request has completed is identified. However, if the order of manufacturing processes is fixed depending on the type of steel product, part, and component, the completed progress status may be identified from the progress status up to that point, without checking the manufacturing process that the person in charge is responsible for. Also, in a manufacturing process that takes a relatively long time, such as a welding process, a progress processing request may be sent when the welding process begins and ends, respectively, to manage the progress status of the manufacturing process in more detail. In other words, a manufacturing process that is usually classified as one may be managed with multiple progress statuses.

In addition, various detailed files are registered to manage the progress, but it is also possible to manage the progress by inputting necessary information in a form other than the registration of various detailed files. This allows for various modifications to the input of information that enables progress management, in other words, the way in which the steel frame design results for an ordered project are handled.
