Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention distributes various types of box-shaped cargo to a plurality of containers, and carries out the packing arrangement of the distributed cargo within each container. It relates to a planning support system.

[Conventional technology]

The stowage planning support system uses a computer to input information such as specifications of containers such as pallets and containers, specifications of cargo to be stowed (hereinafter referred to as cargo to be stowed), and input information such as the quantity of cargo to each container. It is a system to support the work of deciding the distribution of cargo and the loading of cargo in each container. A conventional example of this system is shown in Japanese Patent Laid-Open No. 60-197530, and a container master file for storing specifications (dimensions, weight limits, etc.) of each container, specifications of cargo with cargo (cargo size, We used files such as a cargo file that stores the weight, etc., a distribution information file that stores the distribution information of the loaded cargo to each container, and a loading result file that stores the loading coordinates of the cargo for each container. The procedure for the stowage plan is No. 6
As shown in the figure, first enter the specifications of the container and the cargo to be loaded into the container master file and the cargo specification file (step 501), and then use the volume of the container and the cargo to be entered here as the basis for the volume ratio. As a result, the distribution of the cargo to be stowed to each container is decided and stored in the distribution information file (step 50
2) Finally, the loading position for each container is determined with stable loading of each cargo, taking into consideration conditions such as upside-down and workability, and the result is stored in the loading result file (step).
503). The method of distributing the cargo to be loaded into each container and determining the loading position in each container is well known in the art, and the description thereof is omitted in the text.

[Problems to be Solved by the Invention]

According to the above-mentioned conventional technique, there are the following problems. First, since the distribution of stowed cargo to each container in step 502 of FIG. 6 is performed in consideration of only the container and the volume of cargo, in the process of determining the stowage position of the cargo distributed to each container. Loading may not be possible. At this time, since it is necessary to return to the distribution processing of step 502 by the determination of step 504 and to retry the creation of the distribution information file, another container already completed and stored in the stowage result file at step 503 is required. Even the stowage results can be lost, which is not efficient. In addition, once the container master file is created, it can be used for many purposes as it is, but the freight file includes the freight code, quantity, and
Workability is poor because all freight specifications such as freight size, weight, stowage conditions, etc. must be manually entered from the keyboard.

The object of the present invention is not only the fixed flow of carrying out the loading process after the distribution of the cargo to be loaded into each container, but also the partial reworking and the dispensing process depending on the result after the loading. Providing a stowage planning support system that enables efficient work by enabling effective use of stowage results already obtained by enabling stowage, etc., and enabling easy input of cargo specifications for stowage. There is.

[Means for Solving the Problems]

The above-mentioned object is to combine the distribution information file and the stowage result file in the prior art into one, and to store the stowed container, stowed position, stowed state, etc. for each stowed cargo. Achieved by providing an expanded cargo file that stores the results of the shipping plan, and the cargo code that represents the type of cargo and the cargo specifications such as the size, weight, and stowage conditions of the cargo with this code are stored in advance. This is achieved by newly providing a cargo master file.

[Work]

By providing a developed cargo file with the contents of the conventional distribution information file and the stowage result file merged, the stowage cargo can be distributed in each container as before, and then the stowage processing can be performed in each container. Not only that, by referring to one unfolded cargo file, it is possible to easily know the distribution / stowage results of the stowed cargo up to that point, so partial stowage corrections and additions are possible, and unsold When it occurs, there is no need to redo all of the distribution processing, and fine stowage work is also possible, so workability is greatly improved. Also, by installing the cargo master file, you can enter the cargo code and the required quantity of the cargo to be loaded, and the cargo specifications such as cargo dimensions and weight can be automatically entered in the cargo file by referring to the cargo master file. ,
The time and effort required to create a cargo file can be significantly reduced.

〔Example〕

Hereinafter, the present invention will be described with reference to examples. FIG. 5 is a block diagram showing a hardware configuration example of the stowage planning support system of the present invention. The computer system 1 includes a CPU 11 and a main memory 1.
2. It consists of input / output circuit 13 and bus 14. As the peripheral device, a keyboard 2 for inputting the data for the cargo file 123 in the main memory 12 and a mouse 3 for the operator to directly input the loading position with respect to the loading pattern displayed on the CRT7. Print out the floppy disk drive 4, auxiliary memory 5, loading data, etc. for inputting cargo master file 122, container master file 125, etc., and outputting the calculated loading results for transfer to another computer. It comprises a printer 6 for future use.

Next, the contents of various files used in the system of the present invention will be described. FIG. 2 shows an example of the structure of a cargo master file 122, which is one of the files characteristic of the present invention. The freight code is a number indicating the type of freight, and one number is attached to one type of freight. The dimension consisting of the length L, the width W and the height H and the weight are indispensable specifications for stowage. There are other loading conditions required depending on the cargo to be loaded. For example, if the cargo is light and fragile and needs to be loaded on the top, U is designated as the top loading, and if the top is weak and cannot be loaded on top, the loading is prohibited X. Designates the lower product designation L, and also stores the loading condition such as the designation of useless top and bottom. Once created, this file 122 does not need to be updated except when changing the type of cargo handled.

FIG. 1 shows an example of the structure of an expanded cargo file 124, which is another file characteristic of the present invention. One line of data is stored for each cargo. Freight file
The pointer to the expanded cargo file on 123 and the pointer of the cargo file on expanded cargo file 124 correspond to each other. The contents of the developed cargo file 124 are a container number to which the cargo is distributed, a loading flag indicating whether or not the cargo is loaded, a loading position, a loading state dimension, and a loading number. The stowage flag is "1" if the stowage of the cargo has been decided, and "0" if not decided.
The loading position represents the position of the cargo in the container. The stowed size dimensions represent the length L, width W, and height H when the cargo is actually loaded. This is the length, width, and height of the same cargo registered in the cargo file 123. When they are stowed, they do not match, and the length and width are swapped, resulting in a set of swapped numbers. This is not in the conventional stowage result file. The stowage number indicates the stowage order within each container. In this way, since the expanded cargo file 124 includes all the distribution results, placement results, and stowage results for each freight, save the stowage data up to that point, and then start the stowage. By taking the correspondence with the cargo code, the processing such as using the loading results up to that time can be facilitated, and the processing when there is an unloaded product when deciding the loading position of one container is performed flexibly. Is possible.

FIG. 7 shows an example of the structure of the freight file 123, in which the data of cargo with stowage is stored. This may be the same as the conventional one, and always includes the cargo code and quantity, and stores all specifications of the cargo to be loaded.

FIG. 8 shows an example of the structure of the container master file 125, which may be the same as the conventional one. It has a container code that indicates the type of container, the dimensions inside the container (length L, width W, height H), and the limit weight that can be loaded into the container. Similar to 122, once created, it is not necessary to update it except when changing the type of container to be handled.

In the present invention, the developed cargo file 124 is provided by combining the conventional distribution information file and the stowage result file into one. Therefore, in order to obtain data such as the total weight of each container and the loading position, it is necessary to search the expanded cargo file 124, which takes time. Therefore, as a file corresponding to the conventional distribution information file, a container management file 126 for storing aggregate data of the distribution state and the loading state of the cargo for each container is edited and created in advance. An example of this structure is shown in FIG. 9, and the container number attached to each container to be used, the container code indicating the type of the container, the container size, the limit weight, the number of cargoes loaded, the loading efficiency ( Volume ratio),
The contents of the loading weight and the flag that becomes "1" when loading is completed. However, the conventional distribution information file shows the distribution result and was used as an input for the loading process, but in the present embodiment, it is simply aggregate data for each container of the loading result,
It is used to grasp the progress of the entire stowage planning work.

Next, a procedure for creating a plan by the system of the present invention using the various files described above will be described. 3 and 4 are flowcharts showing the procedure, which are loaded as a program 121 (FIG. 1) on the main memory. It is also assumed that the container master file 125 and the cargo master file 122 are created in advance. The loading plan when multiple cargos are given is first shown in Fig. 3 step.
Begins with the creation of cargo file 123 at 301. The details of this step 301 are shown in FIG. 4, and when the cargo code to be loaded is entered from the keyboard 2 (step 401), the cargo master file 122 is searched (step 402), and the cargo code concerned is found. For example, various specification data corresponding to the code are read and input to the cargo file 123 (step 403). If the entered cargo code is not registered in the cargo master file 122, enter the quantity of cargo required for loading from the keyboard 2 (step 405),
It is judged whether or not all the given types of cargo have been input (step 406), and the process ends. As described above, by providing the cargo master file 122, it is not necessary to input the data such as the size, weight, and stowage condition of the cargo one by one, so that the efficiency of the input work can be greatly improved.

Once the freight file 123 is created, step 3 in Figure 3
In 02, it is determined whether or not the distribution process is performed. If it is not done, it goes directly to the container loading work, but if it is done, it goes to step 303 and distributes the loaded cargo to each container taking into account the specified volume ratio from the capacity of the container and the volume of the cargo. I do. This distribution method is the same as the conventional one, and various processing can be performed by using various parameters. The number of the container designated for each cargo by this distribution is set at the distribution container number in the column of the code representing the cargo in the expanded cargo file 124 (FIG. 1). In the stowage process in step 304, the stowage position in the container is determined for the distributed cargo for each container number in the expanded cargo file 124. In this system, when the stowage design screen is displayed after the container number is specified, the distributed cargo is displayed in the container number, and the loading position of the next cargo is specified using the mouse while observing it. Go on. In addition, a conventional command for automatically determining the arrangement is also prepared. When the stowage position is determined, the stowage flag of the relevant cargo in the developed cargo file 124 is set, and the stowage position, the dimension in the stowed state, and the stowage number are set. If some of the cargo that has been distributed cannot be stowed, the shipping container number will be canceled at the time of the registration processing of the stowage result to leave it undistributed. When the loading process for each container is completed (step 305), it is determined whether or not there are unshipped cargoes (step 306), and if there is unshipped cargo, the process returns to step 304 for the unshipped cargo and the loading design screen is displayed. Specify an unused container number when opening. Then use the undistributed cargo call command to expand the cargo file 124
On the screen, display the cargos for which the distribution container numbers in No. are not set, and in the same way as above, determine the loading position for the unshipped cargoes in the new containers. Then, at the time of the registration processing of the stowage result, the data below the stowage flag of the expanded cargo file 124 is set and the current container number is set.
With the above, the stowage process is completed.

〔The invention's effect〕

According to the present invention, since information on distribution of cargos to containers and arrangement positions is stored in one unfolded cargo file, processing such as partial stowage correction and priority cargo stowage by an operator for some cargos is performed. It has the effect that it can be done easily, and the efficiency of creating a loading plan for each container can be greatly improved, and that the time required for inputting cargo data can be greatly shortened by providing a cargo master file. effective.
