Description

The present invention relates to a production process management system and a production process management method.

Generally, when concrete components are used in civil engineering and construction work, either the cast-in-place method, in which concrete is poured at the construction site to complete the concrete components, or the precast method, in which concrete components are produced in a factory and brought to the construction site, is used.

With the precast method, concrete components produced in a factory must be transported to the construction site, but there is no need to pour the concrete at the construction site. In addition, by producing concrete components in a factory with appropriate equipment and an inspection environment, the precast method is expected to ensure high quality, stable quality, and work safety, and it can shorten construction times and reduce the number of workers required at construction sites.

By the way, in civil engineering works, construction sites, factories, and other workplaces where products are manufactured, various efforts are being made to improve production efficiency.

For example, Patent Document 1 discloses technology relating to a work data management system that makes it easy to grasp the work content at a work site. Specifically, the work data management system disclosed in Patent Document 1 classifies the work performed by workers at the work site into multiple chronological detailed processes based on video data of the work site, and visualizes the video data and the detailed processes. In this way, by grasping the work content at each detailed process, product quality and productivity are improved.

JP 2019-16226 A

However, the work data management system described in Patent Document 1 classifies work site video data into detailed processes and performs various data analyses, which creates the problem that multiple cameras must be installed in appropriate locations at the work site to cover a wide area and avoid blind spots.

In addition, because precast concrete factories are equipped with large facilities, equipment, and components, even if multiple cameras are installed, it is not easy to perform various analyses based on video data over a wide area of the factory. In addition, if the factory is semi-outdoors, dust, etc. can make camera maintenance difficult.

The present invention aims to provide a production process management system and a production process management method that can appropriately manage the production process.

Note that the embodiment described below is merely a specific example for implementing the present invention, and is not intended to limit the interpretation of the present invention.

<One embodiment>
[Configuration of production process control system]
Fig. 1 is a system overview diagram showing a production process control system 10 according to one embodiment of the present invention. As shown in Fig. 1, the production process control system 10 is composed of a data collection system 100 that collects data from a positioning system 20 and a production control system 30, etc., and a data analysis system 200 that analyzes the data from the data collection system 100.

The data collection system 100 includes a location information acquisition unit 110, a production process information acquisition unit 120, a worker information acquisition unit 130, a data recording unit 140, and a transmission unit 150, and the data analysis system 200 includes a receiving unit 210, a process judgment unit 220, and a display unit 230.

In this embodiment, the production process of precast concrete is taken as an example, and the data collection system 100 is placed in a precast factory and the data analysis system 200 is built in the cloud, but this is not limited to this. For example, a single production process management system 10 may be placed in a precast factory, may be built in the cloud, or may be placed and built in another location that manages a server system, etc.

The location information acquisition unit 110 acquires location information of construction equipment used in the production process of the construction components. In this embodiment, the construction components are precast concrete and the construction equipment is a concrete pouring machine, so specifically, the location information acquisition unit 110 acquires location information of the concrete pouring machine (first location information acquisition unit).

For example, a positioning system such as a real-time location system (RTLS) and an indoor positioning system (IPS) is constructed in a precast factory, and a locator is placed to collect position information (positioning data). The locator typically receives the position information (positioning data) of the concrete pouring machine from a transmitter attached to the concrete pouring machine via wireless communication such as Bluetooth (registered trademark), UWB (Ultra Wide Band), and Wi-Fi (registered trademark). Furthermore, the positioning data may be acquired using GNSS or the like.

The location information acquisition unit 110 may also acquire location information of workers working in the precast factory (second location information acquisition unit). For example, a transmitter may be attached to a helmet, work clothes, shoes, or belt worn by the worker, or the worker may carry a transmitter or a communication device carried by the worker (e.g., a smartphone, tablet, etc.) may be equipped with a dedicated application. Basically, the transmitter is implemented in a manner that allows the worker to wear it at all times. The locator can also collect location information (positioning data) of the worker.

The transmitters attached to the concrete pouring machine and the worker may transmit positioning data to the locator, for example, every 0.1 to 5 seconds. The interval at which the transmitter transmits positioning data is not limited to every 0.1 to 5 seconds, and may be set appropriately based on the accuracy required by the system, for example, for the location information of the concrete pouring machine and the worker. Also, different settings may be used for each construction machine and worker.

In this way, the location information acquisition unit 110 acquires location information, such as the identification information (ID) of each transmitter, coordinates, and time, regarding where the concrete pouring machine and each worker are located within the precast factory.

The production process information acquisition unit 120 acquires production process information related to the production process of precast concrete. For example, the production process information acquisition unit 120 acquires production process information managed by the production management system 30. Here, the production process information includes, for example, detailed component information for each component, pouring date, pouring location, and other information related to the production process for construction components including precast concrete.

The production process information acquisition unit 120 is not limited to acquiring production process information from the production management system 30, but may acquire, for example, production process information pre-recorded in a database constructed in the production process management system 10, or may acquire production process information recorded in another system.

The worker information acquisition unit 130 acquires worker information including the production processes that the worker can be responsible for among the production processes. For example, the worker information acquisition unit 130 may acquire worker information that is pre-recorded in a database constructed in the production process management system 10, or may acquire the worker information from another system in which the worker information is recorded. For example, if the worker information is recorded in the above-mentioned production management system 30, the worker information may be acquired from the production management system 30.

Here, worker information refers to information about workers working in a precast factory, and includes, for example, information about which production process the worker is available to handle, linked to identification information (ID) or name, and may also include various personal information about the worker's industry, gender, age, experience, skills, nationality, address, etc.

The data recording unit 140 may record and further store the location information (positioning data) of the concrete pouring machine and the worker acquired by the location information acquisition unit 110, the production process information acquired by the production process information acquisition unit 120, and the worker information acquired by the worker information acquisition unit 130. Note that the location information (positioning data) of the concrete pouring machine and the worker, the production process information, and the worker information may not be stored in the data recording unit 140, but may be directly transmitted to the data analysis system 200 by the transmission unit 150. In this case, the data recording unit 140 may be included in the data analysis system 200.

The transmission unit 150 transmits various information recorded (stored) in the data recording unit 140 to the data analysis system 200, for example, via the Internet.

The receiving unit 210 receives various information transmitted by the transmitting unit 150 of the data collection system 100.

The process determination unit 220 analyzes the precast concrete production process based on the various information received by the receiving unit 210. Specifically, the process determination unit 220 determines the duration of the equipment use process in which the concrete pouring machine is used based on the location information of the concrete pouring machine during the production process. The equipment use process in which the concrete pouring machine is used is the pouring process in which concrete is poured into a set formwork. Generally, the concrete pouring machine remains in a specified area during the pouring process, so if the process determination unit 220 determines that the concrete pouring machine is continuously staying based on the location information of the concrete pouring machine, it can determine the pouring process duration.

The process determination unit 220 also determines the process durations of the production process other than the casting process based on the production process information. For example, the process determination unit 220 generally determines the setting process and inspection process that are performed before the casting process, the finishing process that is performed in parallel with the casting process, and the demolding process that is performed after the casting process.

The setting process is a preparation for the casting process, typically involving assembling a formwork and inserting rebar into the formwork, and the inspection process is a process involving inspecting the formwork and rebar. The finishing process is a process for smoothing the concrete casting surface of the precast concrete, the demolding process is a process for removing the precast concrete from the formwork (removing the formwork), and the forging process is a process for machining the steel formwork to match the shape, hole positions, etc. to the components.

The processes determined by the process determination unit 220 are not limited to these, and may include, for example, a reinforcing bar process, a product inspection process, and a curing process, or may be further subdivided processes, etc.

In this way, the process determination unit 220 can determine the duration of the pouring process using a concrete pouring machine based on the location information of the concrete pouring machine, and can determine the duration of each process in the production process based on the pouring process duration and the production process information, which includes detailed component information for each component, the pouring date, the pouring location, and other information related to the production process, for construction components including precast concrete.

The process determination unit 220 may also determine the start and end of at least one or more process periods included in the production process based on the worker's location information and worker information. Generally, each process included in the production process has a designated work area within the precast factory, and the type of worker who can handle each process is also determined. The process determination unit 220 checks which process each worker can handle based on the worker information, and in which area each worker continues to stay based on the worker's location information, and confirms the start and end times of that stay. This allows the process determination unit to grasp each process period in more detail and in line with the actual situation.

The process determination unit 220 may determine the duration of each process other than the pouring process by determining the pouring process duration and using the determined pouring process duration as a reference, or may determine the duration of each process other than the pouring process based on the worker's location information and worker information, together with or before determining the pouring process duration. For example, the process determination unit 220 may determine the form stripping process duration based on the worker's location information and worker information, and determine the pouring process duration based on the location information of the concrete pouring machine. The durations of other processes (such as the setting process, inspection process, and finishing process) may then be determined based on the determined form stripping process duration and pouring process duration.

Furthermore, the process determination unit 220 determines the work performance for at least one or more process periods included in the production process based on the worker's location information and worker information. The process determination unit 220 can determine the work performance for each process period by checking which process each worker is capable of taking charge of based on the worker information, and in which area each worker continues to stay based on the worker's location information.

Specific details regarding the process period and work performance determined by the process determination unit 220 described above will be described later.

The display unit 230 displays the process period and work results determined by the process determination unit 220. For example, to make the production process management easier to understand visually, the display may be in tabular form on the screen, each process may be displayed in a different color, the work results may be displayed for each worker, or displayed in graph form. Furthermore, the display unit 230 is not limited to the display unit 230 in the production process management system 10, and may be notified by email or displayed on the display unit of a different system, for example.

[Details of process period and work performance]
Next, the process period and work results will be described in detail with specific examples.
2 is a diagram showing how the duration of a pouring process (a process using equipment) in a production process is determined in a production process management system 10 according to an embodiment of the present invention. As shown in FIG. 2, the duration of a pouring process of precast concrete (PC member) B in the production process is determined.

The process determination unit 220 determines the period of the concrete pouring process using the concrete pouring machine based on the position information of the concrete pouring machine. Specifically, the process determination unit 220 confirms that the concrete pouring machine for pouring the PC member B is continuously present in the area where the pouring process is carried out, and determines the pouring process period (11:00 on February 1, 2020 to 4:00 on February 2, 2020).

Here, whether or not the concrete pouring machine is stalled can be determined not only when it remains in the exact same position, but also when it remains in a specified area (first area) for a specified time (first threshold). For example, it is possible to avoid erroneous determination of the pouring process period depending on errors (changes) in the position information caused by adjustments to the concrete pouring machine, detection errors in the position information, and unexpected events. In addition, the first threshold is at least the dwell time required for the pouring process, and if there is a period in which the machine remains stalled for a specified time, that period means that the machine is stalled.

Furthermore, the process determination unit 220 may determine the casting process period after confirming that the stripping process of the front component (PC component A) has been completed as part of the schedule based on production process information, etc.

Figure 3 is a diagram showing how the process durations of the production process other than the pouring process are determined in the production process management system 10 according to one embodiment of the present invention. As shown in Figure 3, the setting process, inspection process, demolding process, finishing process, and forging process of precast concrete (PC member) B are determined among the production processes.

The process determination unit 220 determines the demolding process period (from 4:00 am on February 2, 2020 to 8:00 am on February 2, 2020) based on production process information, etc. The process determination unit 220 may determine the demolding process period after confirming that the concrete pouring machine is not continuously present in the area where the pouring process is performed.

The process determination unit 220 determines the setting process period and inspection process period (8:00am to 11:00am on February 1, 2020) after the completion of the demolding process of the previous component (PC component A) and before the start of the casting process of PC component B, based on the production process information, etc.

The process determination unit 220 determines the finishing process period (11:00 on February 1, 2020 to 4:00 on February 2, 2020) from the start of the pouring process of PC component B until the start of the demolding process based on production process information, etc.

Furthermore, the process determination unit 220 may determine the forging process period (8:00 on February 1, 2020 to 4:00 on February 2, 2020) from the end of the demolding process of PC component A to the end of the casting process of PC component B based on production process information, etc.

In this way, the process determination unit 220 determines the pouring process period for PC member B based on the location information of the concrete pouring machine, and determines the process periods other than the pouring process based on the pouring process period and the production process information, etc., thereby determining the duration of each process in the production process. Since the production process information includes detailed component information for each PC member, the pouring date, the pouring location, and other information related to the production process, it is possible to determine the duration of each process in the production process for each PC member, and by combining these, it is possible to determine the duration of each process in the production process for multiple PC members or for the entire project. Furthermore, it is possible to determine the duration of each process in production processes carried out not only at one precast factory, but also at multiple precast factories, and even at construction sites and other locations.

Here, the casting process period of the production process of PC component B is determined, and the process periods other than the casting process are determined based on the casting process period, production process information, etc., and the production process of the previous component PC component A (end of the demolding process), but this is not limited to this. For example, if the end date and time of the demolding process of the previous component PC component A cannot be obtained, the setting process period, inspection process period, blacksmithing process period, etc. of PC component B may be determined using 8:00 a.m. on the day after the casting process date of PC component A (for example, January 31, 2020) (February 1, 2020) as the end date and time of the demolding process of PC component A, or judgment conditions may be set in advance in the production process information, etc., and judgment may be made based on those conditions.

As described above, the process determination unit 220 determines the pouring process period based on the location information of the concrete pouring machine, and determines the periods of each process other than the pouring process based on production process information, etc., but when making these determinations, the start and end times of each process period may be determined using the location information and worker information of the worker.

For example, the process determination unit 220 determines when a worker in a production process that the worker can handle starts and ends staying continuously in the area where the process is performed, and determines the start and end times of the process period. By determining the start and end times for each process based on the worker's location information, the process period can be determined in more detail and in line with the actual situation. In other words, there may be blank periods between processes that do not belong to any process period (or there may not be any), and these can also be identified. Details of the process that the worker can handle and the method of determining whether the worker is staying in the area where each process is performed will be described later.

The process determination unit 220 may determine the casting process period based on the location information of the concrete pouring machine, and then determine the periods of each process other than the casting process based on the production management information, the location information of the worker, and the worker information, or a combination of these, or may determine some or all of the periods of each process other than the casting process before or at the same time as determining the casting process period. For example, the process determination unit 220 may determine the form stripping process period based on the location information of the worker and the worker information, and determine the casting process period based on the location information of the concrete pouring machine. Then, the periods of other processes (setting process, inspection process, finishing process, etc.) may be determined based on the determined form stripping process period and casting process period.

Figure 4A is a diagram showing how the process periods included in the production process are determined in a production process control system 10 according to one embodiment of the present invention, and Figure 4B is a diagram showing how the work performance for the process periods included in the production process is determined in a production process control system 10 according to one embodiment of the present invention. As described above, Figure 4A shows how each process period in the production process for each PC component is determined, and Figure 4B shows how the work performance of worker a during the demolding process period and the setting process period, and the work performance of worker b during the inspection process period are determined. Here, we will explain in detail how the work performance of each worker is determined for the process periods included in the production process.

The process determination unit 220 determines the work performance during at least one process period included in the production process based on the location information and worker information of the workers. Based on the location information and worker information of worker a, the process determination unit 220 determines the work performance during the demolding process period for PC component A (4:00 on February 1, 2020 to 7:00 on February 1), the work performance during the setting process period for PC component B (8:00 on February 1, 2020 to 10:00 on February 1), and the work performance during the demolding process period (4:00 on February 2, 2020 to 7:00 on February 2). Based on the location information and worker information of worker b, the process determination unit 220 also determines the work performance during the inspection process period for PC component B (8:00 on February 1, 2020 to 9:00 on February 1).

Specifically, the process determination unit 220 confirms, based on the worker information of worker a, that worker a is available to handle the demolding process, and, based on the position information of worker a, that worker a is continuously present in the area where the demolding process of PC component A is carried out, and determines that worker a is working in the demolding process of PC component A. Similarly, the process determination unit 220 determines that worker a is working in the setting process and demolding process of PC component B.

The process determination unit 220 also determines, based on the worker information of worker b, that worker b is available to handle the inspection process, and based on the position information of worker b, that worker b is continuously present in the area where the inspection process of PC component B is carried out, and determines that worker b is working in the inspection process of PC component B.

Here, which production processes each worker is capable of taking charge of can be determined based on information contained in the worker information, such as information about the processes each worker is capable of taking charge of that correspond to the industry to which each worker belongs.

Figure 5 is an example showing the production processes that a worker can be responsible for, corresponding to the industry to which the worker belongs. As shown in Figure 5, a worker in the "set" industry can be responsible for the setting process and the demolding process, a worker in the "casting" industry can be responsible for the setting process, the casting process and the demolding process, a worker in the "finishing" industry can be responsible for the setting process, the casting process, the finishing process and the demolding process, a worker in the "inspector" industry can be responsible for the inspection process, and a worker in the "blacksmith" industry can be responsible for the blacksmithing process. In this embodiment, worker a is in the "set" industry, and worker b is in the "inspector" industry.

Furthermore, with regard to whether or not each worker is staying in the area where each process is performed, it may be determined that the worker is staying not only when the worker remains in the exact same position, but also when the worker remains in a specific area (second area) where each process is performed for a specific period of time (second threshold value).

For example, when a worker performs work in each process, it is possible to avoid erroneous judgments of the worker's work performance due to movement in the area where each process is performed, detection errors in the location information, and errors (changes) in the location information caused by sudden events, etc. Also, there may be workers who temporarily enter or pass through the area even though they are not performing the work in that process, and it is possible to avoid erroneous judgments due to the behavior of such workers, etc. The second threshold value is at least the residence time required for each process, and for example, if there is a period during which a certain period of time is spent, it means that the period is spent.

Figure 6 is an example showing (1) the possible trades for each process, and (2) the residence time (second threshold) required to determine that a worker of that possible trade is performing work in that process. As shown in Figure 6, the possible trades are set for each of the setting process, inspection process, pouring process, finishing process, demolding process, and blacksmithing process, and the residence time (second threshold) for determining that the process is being performed is set for each process.

As described above, in this embodiment, worker a is in the "set" category and is responsible for the setting process and the demolding process, and worker b is in the "inspector" category and is responsible for the inspection process.

Based on the position information of worker a, the process determination unit 220 counts the time during which worker a remains in the area where the demolding process of PC component A is carried out for 12 seconds or more within one minute within the range from "February 1, 2020, 4:00" when the worker a first remains in the area for 12 seconds or more until "February 1, 2020, 7:00" when the worker last remains in the area for 12 seconds or more as the work performance during the demolding process of PC component A.

Figure 7 shows how the work performance of worker a during the demolding process of PC component A is tallied. As shown in Figure 7, if worker a remains in the area where the demolding process of PC component A is carried out for 12 seconds or more per minute, he or she is determined to be in the area, and that time is recorded as work performance.

Similarly, based on the position information of worker a, the process determination unit 220 determines the time during which worker a stayed in the area where the setting process of PC component B is performed for 12 seconds or more per minute within the range from "February 1, 2020, 8:00," when the time period during which worker a stayed in the area where the setting process of PC component B is performed was first confirmed to be 12 seconds or more, to "February 1, 2020, 10:00," when the time period during which worker a stayed in the area where the setting process of PC component B is performed was last confirmed to be 12 seconds or more, as the work performance during the setting process period of PC component B, and determines the time during which worker a stayed in the area where the demolding process of PC component B is performed for 12 seconds or more per minute within the range from "February 2, 2020, 4:00," when the time period during which worker a stayed in the area where the demolding process of PC component B was performed was first confirmed to be 12 seconds or more, to "February 2, 2020, 7:00," when the time period during which worker a stayed in the area where the demolding process of PC component B is performed was last confirmed to be 12 seconds or more, as the work performance during the demolding process period of PC component B.

In addition, based on the position information of worker b, the process determination unit 220 determines that the time that worker b stayed in the area where the inspection process of PC component B is carried out for 26 seconds or more per minute within the range from "February 1, 2020, 8:00" when the first confirmed period of time that worker b stayed in the area for 26 seconds or more to "February 1, 2020, 9:00" when the last confirmed period of time of staying in the area for 26 seconds or more is the work performance for the inspection process period of PC component B.

The work performance of worker a and worker b in each process of each PC component may be determined by linking it to the process period of each process in the production process determined by the process determination unit 220 as shown in FIG. 4A, or may be determined by taking into account the location information of the concrete pouring machine. For example, if the process periods that workers are available to handle overlap, if the concrete pouring machine is stalled, it is determined as the work performance of the pouring process, and if the concrete pouring machine is not stalled, it is determined as the work performance of the finishing process.

Furthermore, here, the dwell time (second threshold) in each process is set to the value shown in FIG. 6, but is not limited to these. For example, an appropriate dwell time (second threshold) may be set for each process depending on the skill of the worker, the size, shape, and type of the PC component, the equipment and environment used in each process, and various other factors.

In this way, the process determination unit 220 checks worker information including information about the processes each worker can handle, while determining in which area each worker is continuously staying based on the location information of each worker, thereby determining the work performance for at least one or more process periods included in the production process. This makes it possible to determine the work performance for each process period of each PC component for each worker, and by combining these, it is possible to determine the work performance for each process period in the production process of multiple PC components or the entire project. Furthermore, it is possible to determine the work performance for each process period of production processes carried out not only at one precast factory, but also at multiple precast factories, and even at construction sites and other locations.

[Production process control method]
Next, the procedure for carrying out production process management will be specifically described in detail.

Figure 8 is a flowchart showing a production process management method M10 executed by a production process management system 10 according to one embodiment of the present invention. As shown in Figure 8, the production process management method M10 includes steps S110 to S150, and each step is executed by a processor included in the production process management system 10.

In step S110, the production process management system 10 acquires various information. As a specific example, the position information acquisition unit 110 acquires position information (positioning data) of the concrete pouring machine and the worker from the positioning system 20, and the production process information acquisition unit 120 acquires production management information from the production management system 30. In addition, the worker information acquisition unit 130 acquires worker information. Note that this various information is stored in, for example, the data recording unit 140.

In step S120, the production process management system 10 determines the equipment use process period. As a specific example, the process determination unit 220 determines the pouring process period based on the position information of the concrete pouring machine.

In step S130, the production process management system 10 determines the duration of processes other than the equipment use process. As a specific example, the process determination unit 220 determines the duration of processes other than the casting process based on the production process information, the worker's location information and the worker information, or a combination of these. For example, the process determination unit 220 determines the setting process and the inspection process that are performed before the casting process, the finishing process that is performed in parallel with the casting process, and the demolding process that is performed after the casting process.

Note that, here, the production process management system 10 determines the process period other than the equipment use process in step S130, but some or all of the processes other than the equipment use process may be determined before or during the determination in step S120.

In step S140, the production process management system 10 judges the work performance for each process period. As a specific example, the process judgment unit 220 judges the work performance for at least one process period included in the production process based on the worker's location information and worker information.

In step S150, the production process control system 10 displays each process period and work performance. As a specific example, the display unit 230 displays each process period and work performance determined in steps S120 to S140 on a monitor or the like. For example, the display unit 230 displays each process period and work performance in a format such as that shown in Figures 4A and 4B. The display format may also be other formats such as tables, graphs, data, etc.

As described above, according to the production process management system 10 and production process management method M10 of one embodiment of the present invention, the process determination unit 220 determines the pouring process period based on the location information of the concrete pouring machine, and determines the process periods other than the pouring process based on the production process information, the worker's location information and worker information, or a combination of these. The process determination unit 220 then determines the work performance in each process period based on the worker's location information and worker information. As a result, the production process can be managed by appropriately determining the process period, and the production process can also be managed more appropriately by taking into account the work performance.

In this embodiment, the processing has been described mainly in terms of the production process of one component (PC component B) and is generally performed on a daily (24 hour) basis. However, the production process management system 10 may process, for example, the production processes of multiple components on a weekly, monthly, or project-by-project basis for a specified period. Specifically, the production process management system 10 may determine the pouring process period for each of the multiple components based on one month's worth of data accumulated in the data recording unit 140, and then determine the process periods other than the pouring process for each of the multiple components.

In this embodiment, the construction equipment is described as a concrete pouring machine, but is not limited to this, and may be, for example, a concrete pump truck and a ready-mixed concrete hopper. Furthermore, the construction members are not limited to concrete members, and may be other construction members. In that case, the construction equipment is not limited to a concrete pouring machine or ready-mixed concrete hopper, but may be construction equipment corresponding to the other construction members.

In addition, when the present invention is applied to the production process management of construction members other than concrete members, the equipment use process does not have to be a pouring process, but may be a process that uses the construction equipment in question, and the process other than the equipment use process may be a process corresponding to the production process of construction members other than concrete members.

In addition, a precast construction method in which concrete components are produced in a precast factory rather than at the construction site has been given as an example, but this is not limited to this, and the production process management system 10 of the present invention can also be applied to a cast-in-place construction method in which concrete is poured at the construction site.

Furthermore, the present invention is not limited to the management of production processes for concrete components, but can also be applied to the management of production processes for other construction components, civil engineering work sites, construction sites, ALC factories, and GRC factories, as well as production processes in other industries.

The above-described embodiments are intended to facilitate understanding of the present invention, and are not intended to limit the present invention. The elements of the embodiments, as well as their arrangements, materials, conditions, shapes, sizes, etc., are not limited to those exemplified, and may be modified as appropriate. Furthermore, configurations shown in different embodiments may be partially substituted or combined.
