Description

  The present invention relates to a storage operation support method and a storage operation support processing device for a product storage provided in a steel product manufacturing facility and stacked and stored until the steel product is shipped.

  In the steel product manufacturing facility, in the product place provided in the factory, the place operation of storing the finally produced steel product until shipment is performed. In general, in order to make effective use of the floor area of the product storage area, product storage areas are provided according to size by dividing the product storage area according to the size of the product. The area ratio of the product storage area for each size is determined based on, for example, the product ratio (product mix) of each size. However, since this product mix changes depending on market needs, a product storage of a certain size may temporarily become insufficient, or vice versa.

  Here, a temporary storage place is provided in the storage place, and what is prepared for the shortage of the storage place by performing a storage operation using this temporary storage place is known. For example, in Patent Document 1, a temporary reception place in which a maximum-size article that can be stored can be placed in a warehouse having a table or a shelf for each size of the article to be stored (for example, a coil). Then, when there is no space on the cradle or shelf, the article is temporarily stored in the temporary storage area, and the warehousing control of the article on the cradle or shelf is performed by repeatedly determining the storage destination of the article in the temporary reception area. ing.

  Hereinafter, with reference to the drawings, an embodiment for implementing a storage operation support method and a storage operation support processing apparatus for product storage according to the present invention will be described. Note that the present invention is not limited to the embodiments. Moreover, in description of drawing, the same code | symbol is attached | subjected and shown to the same part.

  First, a steel product manufacturing facility to which the product site operation support method and the site operation support processing apparatus of the present embodiment are applied will be described. FIG. 1 is a diagram showing a facility outline of a steel product manufacturing facility 1. As shown in FIG. 1, a steel product manufacturing facility 1 includes a rolling machine 11 that rolls steel sheets, a cutting machine 13 that cuts steel sheets rolled by the rolling machine 11 into predetermined dimensions, and a cutting machine 13. An inspection device 15 for inspecting the cut steel product and a product storage 17 for storing the steel product that has passed the inspection by the inspection device 15 are arranged in series in this order, and the steel product (thick steel plate; Hereinafter, it is referred to as “plate product”.

  The product storage site 17 temporarily stores the plate-shaped product that has arrived from the inspection device 15, and the plate-shaped product that has arrived from the inspection device 15 via the temporary storage site 171 or directly. And a bookroom 173 for keeping books until the plate-shaped product is shipped. The main storage 173 is divided into a plurality of spaces, and in each of the partitioned main storage 173, the plate-like products carried into the main storage 173 are stacked and stored as separate piles for each shipping lot. Is done. In the present embodiment, for example, the same kind of plate-like product group having the same shipping scheduled date and the same destination (shipping destination) such as a customer or a relay base is set as one shipping lot, and is different in the same main place 173. Operate the yard so that plate products in the shipping lot do not mix. On the other hand, in the temporary storage 171, the plate-like products are stacked and stored, for example, in the order of being loaded into the temporary storage 171 regardless of the difference in shipment lots. The temporary storage 171 is also provided with a plurality of temporary storages 171 as appropriate.

  In addition, the actual product place 17 does not clearly distinguish the temporary place 171 and the main place 173. That is, the product storage 17 has a configuration in which a plurality of storage spaces are provided by dividing the space according to the size of the plate-like product that arrives at the product storage space 17. One or a plurality of places are used as the temporary place 171, and other places are used as the main place 173.

  FIG. 2 is a block diagram showing an example of the overall configuration of the product storage operation system 2 in the present embodiment. As shown in FIG. 2, the product storage operation system 2 includes a storage operation support processing device 3, a database 4, a terminal 5, and a distribution device 6, and the database 4, the terminal 5, and the distribution device 6 support the storage operation. It is connected to the processing device 3 and configured to be able to send and receive data to and from each other.

  The placement operation support processing device 3 includes various storage devices such as a CPU, various IC memories such as ROM and RAM such as flash memory that can be updated and recorded, a storage medium such as a hard disk and a CD-ROM, a communication device, a display device, and a printing device. This can be realized by a known hardware configuration including an output device, an input device, an interface device for connecting each unit, or connecting an external input. For example, a general-purpose computer such as a workstation or a personal computer can be used. This storage site operation support processing device 3 predicts future inventory status changes of the temporary storage site 171 and the main storage site 173 by simulating the loading and unloading of plate products in the temporary storage site 171 and the main storage site 173, and will be described later with a crane, etc. A process (placement operation support process) for proposing the operation of the temporary storage 171 corresponding to the stock status (the number of empty spaces) of the temporary storage 171 and the main storage 173 is performed in consideration of the handling amount of the handling facility.

  The database 4 stores and manages data used for the placement operation support process. The database 4 stores a product information file 41, an inventory status file 43, a placement operation restriction file 45, and an operation instruction file 47, which will be described later with reference to FIG.

  The terminal 5 performs data communication with the placement operation support processing device 3 and displays the result of the placement operation support processing performed by the placement operation support processing device 3. The terminal 5 is realized by a personal computer or the like, for example.

  The distribution equipment 6 includes handling equipment such as a crane for carrying the plate-like products that have finished the inspection by the inspection device 15 and arrived at the product storage 17 to the temporary storage 171 or the main storage 173 and stacked. The physical distribution equipment 6 carries the plate-like products that have arrived at the inspection device 15 into the temporary storage 171 by means of handling equipment and stacks them (temporary placement), or the plate-like products temporarily placed in the temporary storage 171 by means of handling equipment. Carry into the main storage 173 and stack (stack).

  Next, the principle of the placement operation support process according to this embodiment will be described. For the sake of simplicity, in the following explanation of the principle, attention is paid to the two shipping lots A and B that arrive at the product place 17. Here, the shipping lot A and the shipping lot B are each composed of 10 plate products, and the plate product of the shipping lot A and the plate product of the shipping lot B arrive at the product storage 17. The number of sheets per day is one each. One temporary storage 171 and two main storages 173 are used, one main storage 173 is used for storing the shipping lot A, and the other main storage 173 is used for storing the shipping lot B. In addition, the upper limit number of plate products that can be stacked in each temporary storage 171 and main storage 173 is 10 sheets. In actual storage operation, the upper limit height of mountains that can be stacked in each of the temporary storage 171 and the main storage 173 is limited.

  First, without temporarily placing the plate products using the temporary storage 171, the plate products of the shipping lot A and the plate products of the shipping lot B are individually stacked directly on the two main storage sites 173. The transition of the inventory status of each main storage 173 in the case of carrying out will be described. FIG. 3 is a diagram showing the transition of the inventory status of the main storage 173 where the plate products of the shipping lot A are stacked and the main storage 173 where the plate products of the shipping lot B are stacked when temporary placement is not performed. The number of piles in the main lot 173 of the shipping lot A and the main lot 173 of the shipping lot B (the shipping lot A being stacked at the time corresponding to the elapsed days in the corresponding main lot 173 with respect to the elapsed days Or the number of plate-like products in the shipping lot B). FIG. 4 is a graph showing the inventory status of each main storage 173 shown in FIG. 3 with the elapsed time on the horizontal axis and the number of piles on the vertical axis.

  In the example of FIGS. 3 and 4, the first plate-like product of the shipping lot A arrives at the product store 17 on the first day of the elapsed days, and is carried into the main store 173 of the shipping lot A. After that, the plate-like products are loaded and stacked one by one every day, and the shipping lot A is loaded in the main lot 173 of the shipping lot A on the 10th day. The shipping lot A is shipped to the destination on the 12th day, two days after the shipment is completed, and the number of crests in the main lot 173 of the shipping lot A on the 11th day is “0”, and the shipping lot The main storage 173 of A becomes empty.

  On the other hand, the first plate product of the shipping lot B arrives at the product store 17 on the second day after the start of the delivery of the plate product to the main store 173 of the shipping lot A, and is shipped. It is carried into the main storage 173 of lot B. In the main lot 173 of the shipping lot B, the shipping lot B is loaded on the 11th day, and the shipping lot B is shipped to the destination on the 13th day, two days later. Although not shown in FIG. 3, the number of crests in the shipping lot B main storage 173 on the 14th day elapsed is “0”, and the shipping lot B main storage 173 is empty.

  As shown in FIG. 3 and FIG. 4, when temporary placement is not performed, the number of crests is small in the first half of the loading period of the plate-like products of the shipping lot A and the shipping lot B to each main storage 173. Has a low share of plate products. For example, if the number of piles on the day when one or more plate products exist in each main storage 173 between the first day to the 13th day of elapsed time is 6.25 ( Sheet / day), and the occupation ratio in each main storage 173 is 62.5 (% / day). The reason why the day when no plate-like product exists in each main storage 173 is excluded from the denominator of the aggregation is that the explanation of the principle here is the shipping lot A among the shipping lots of plate-like products arriving at the product storage 17. And the shipping lot B, for example, as in the 13th day of the main lot 173 of the shipping lot A or the first day of the main lot 173 of the shipping lot B (the number of crests is “0”). The actual storage 173 is based on the premise that it is actually used for storing another shipping lot.

  Here, since the stay period of each plate-like product in the product storage 17 does not change, if the above-mentioned occupation ratio can be increased, the number of days that each main storage 173 is used for storing the shipping lot A and the shipping lot B In the meantime, each main storage 173 can be used for storing plate-like products of different shipping lots, and the degree of freedom of operation is increased.

  Next, as in FIG. 3 and FIG. 4, the plate-like product of the shipping lot A arrives at the product storage area 17 from the first day to the tenth day, and the shipping lot from the second day to the eleventh day. When the plate-like product of B arrives at the product place 17, the plate-like products of the shipping lot A and the shipping lot B are placed using the two main places 173 while temporarily placing the plate-like product using the temporary place 171. The transition of the inventory status of the temporary storage 171 and the two main storages 173 when stacking and storing individually will be described. FIG. 5 is a diagram illustrating the transition of the stock status of the temporary storage 171, the shipping lot A main storage 173, and the shipping lot B main storage 173 when temporary storage is performed. The number of crests in the main lot 173 of the shipping lot A and the main lot 173 of the shipping lot B is shown. FIG. 6 is a graph in which the inventory status of each temporary storage 171 and main storage 173 shown in FIG. 5 is graphed with the horizontal axis indicating the number of days elapsed and the vertical axis indicating the number of peaks. Here, for example, it is assumed that the number of days for temporarily placing the plate products of the shipping lot A and the shipping lot B in the temporary storage 171 is “5 days”.

  As shown in FIG. 5 and FIG. 6, the first plate product of the shipping lot A arrives at the product storage place 17 and is carried into the temporary storage place 171 on the first day of the elapsed days. On the following second day, two of the second plate product of the shipping lot A and the first plate product of the shipping lot B arrive at the product storage place 17 and are carried into the temporary storage place 171 and, for example, in the order of loading. Stacked. In this example, since the temporary storage days are “5 days”, the plate products of the shipping lot A and the shipping lot B that arrive at the product storage space 17 one by one are carried into the temporary storage space 171 until the fifth day. As a result, the number of piles in the temporary storage 171 on the fifth day is “9”.

  On the sixth day, since the number of temporary storage days is exceeded, the plate products of the shipping lot A among the plate products stacked in the temporary storage 171 are moved to the main storage 173 of the shipping lot A. The plate-like products of the shipping lot B are moved to the main storage 173 of the shipping lot B and stacked. On the sixth day, a new plate product of the shipping lot A and a fifth plate product of the shipping lot B arrive at the product storage area 17, but these plate products are The plate-like product of the shipping lot A is directly carried into the main lot 173 of the shipping lot A without being carried into the temporary storage 171 and stacked, and the plate-like product of the shipping lot B is directly put into the main lot 173 of the shipping lot B. It is carried in and stacked. As a result, the number of crests in the main storage 173 of the shipping lot A on the sixth day is “6”, and the number of crests in the main storage 173 of the shipping lot B is “5”. The inventory status of each main storage 173 on and after the sixth day is the same inventory status as in FIGS. 3 and 4.

  As described above, assuming that the temporary storage place 171 is used and temporary storage of the plate-like product is performed with the temporary storage period set to “5 days”, the temporary storage of the shipping lot A and the shipping lot B is performed up to the fifth day. Since only the storage 171 is used and the two main storages 173 are not used for storage of the shipping lot A and the shipping lot B, the occupation ratio increases to 72.3 (% / day). As a result, as shown in FIG. 3 with hatching, the day when the number of crests is “0” and the corresponding temporary storage 171 or main storage 173 becomes empty is shown in FIG. Compared with the case where the temporary placement is not shown, it is possible to significantly increase. Accordingly, as described with reference to FIGS. 3 and 4, the plate shapes of the shipping lot A and the shipping lot B that arrive at the product place 17 in the first half of the carry-in period when the occupation rate is low when temporary placement is not performed. If the operation of temporary storage by allowing products to be mixed in the temporary storage 171 is allowed, the occupation ratio of the temporary storage 171 and the main storage 173 can be increased, and the number of days when the temporary storage 171 and the main storage 173 become empty is increased. be able to.

  By the way, when performing temporary placement using the temporary storage 171, it is necessary to move the plate-shaped product from the temporary storage 171 to the main storage 173 when the temporary storage days have passed. For example, in the example of FIGS. 5 and 6, nine plate lot products of shipment lot A or shipment lot B are sequentially handled and moved from temporary storage 171 to corresponding main storage 173 on the 6th day. There is a need. As described above, in the storage operation using the temporary storage 171, the handling amount, specifically, the number of handling operations performed to move the plate-like product of the temporary storage 171 to the main storage 173 for each shipment lot increases. To do.

  Therefore, if temporary storage using the temporary storage 171 is performed, the occupation ratio of the temporary storage 171 and the main storage 173 can be increased, and the storage operation using the space of the product storage 17 can be realized efficiently. Such a load increases.

  Therefore, in the present embodiment, simulation of loading and unloading of plate products in the temporary storage 171 and the main storage 173 is performed using the temporary storage days as the operation conditions of the temporary storage 171. In this example, the upper limit number of temporary storage places 171 is set to 10, and the plate products of the shipping lot A and the shipping lot B arrive at the product storage place 17 once a day. 5 days. Specifically, the plate-like products of the shipping lot A and the shipping lot B that arrive at the product storage place 17 before exceeding the temporary storage days are sequentially stacked and temporarily stored in the temporary storage place 171, and the temporary storage days are exceeded. Temporary storage 171 which changes by moving the plate-shaped product in temporary storage 171 to the corresponding main storage 173 at the time and placing the product for each shipment lot and shipping (unloading from main storage 173) on the scheduled shipping date. The future inventory status of the main storage 173 is predicted. Then, an occupancy ratio is calculated and acquired as an evaluation value representing the predicted future inventory status, and the plate products of the shipping lot A and the shipping lot B in the temporary storage 171 are stored in the main storage 173 of the corresponding shipping lot. The number of moving sheets is calculated and acquired as an evaluation value that represents the amount of handling necessary for movement.

  FIG. 7 shows the occupancy rate and the number of moving sheets in each temporary storage day obtained by repeatedly predicting the future inventory status of the temporary storage 171 and the main storage 173 by changing the temporary storage days from 0 to 5 days. The horizontal axis represents the elapsed days and the occupation rate change curve and the moving number change curve are shown. Further, in FIG. 7, for comparison, when temporary placement using the temporary storage place 171 is not performed, that is, a line with an occupation ratio of 62.5 (% / day) in the case where the temporary storage days is 0 is indicated by a one-dot chain line. Show.

  As shown in FIG. 7, paying attention to the occupation ratio, a higher value was obtained when the temporary storage period was set to 4 days or more than when temporary storage was not performed. Specifically, in the case where the temporary storage period is 4 days, the occupation ratio is 66.0 (% / day) and the number of moving sheets is 7. Further, in the case where the provisional number of days is 5, as described above with reference to FIGS. 5 and 6, the occupation ratio is 72.3 (% / day), the number of moving sheets is 9, and in this example, The occupation ratio 6.3 (% / day) corresponds to two moving sheets.

  As described above, the temporary storage days are used as the operation conditions, and the future inventory situation of the temporary storage 171 and the main storage 173 is predicted while changing (adjusting) the temporary storage days, and the relationship between the occupation ratio and the number of moving sheets is obtained. By doing so, it is possible to determine the number of temporary storage days to determine whether the occupancy ratio corresponding to the target temporary storage space 171 and the main storage space 173 can be obtained. Here, the target number of empty spaces varies depending on the expected degree of congestion in the product storage area 17. For example, when the product storage 17 is expected to be crowded due to factors such as the number of plate-like products scheduled to arrive at the product storage 17 in the future or the arrival of shipping lots with a large number of components in the future. The target vacancy number will increase. In such a case, an increase in the load on the handling facility is allowed to some extent by placing a weight on increasing the occupancy rate by increasing the temporary storage days. On the other hand, if the product storage 17 is expected to be comparatively short and there is room in the product storage 17, the storage operation is possible even if the number of empty spaces is reduced to some extent. In such a case, the load on the handling equipment is reduced by reducing the occupancy rate by shortening the temporary storage days and placing a weight on reducing the number of moving sheets. Specifically, in the example of FIG. 7, for example, depending on whether the occupancy rate or the number of moving sheets is weighted, the temporary storage place 171 is set to 4 days and the temporary storage place is set to 5 days. It is possible to quantitatively determine which of the operations 171 is the best. This determination is made by the user, for example.

  FIG. 8 is a flowchart showing the processing procedure of the placement operation support process performed by the placement operation support processing device 3. The placement operation support processing device 3 performs the placement operation support method by performing the placement operation support processing according to the processing procedure of FIG. Note that the processing described here can be realized by storing a program for realizing the placement operation support processing in, for example, the storage device of the placement operation support processing device 3, and reading and executing the program.

  As shown in FIG. 8, the site operation support processing device 3 first executes a data input process as a data input means, reads out and inputs the product information file 41 and the inventory status file 43 from the database 4 (step S1). .

  FIG. 9 is a diagram illustrating a data configuration example of the product information file 41. As shown in FIG. 9, the product information file 41 is associated with the product ID uniquely assigned to the plate-like product arriving at the product storage 17, and the plate thickness (mm) and width ( m), length (m), scheduled shipping date, identification number of the shipping lot, destination code assigned to the destination of the shipping lot, and availability of mixed operation (possible = 1 / impossible = 0) ) And are registered. Here, whether or not the mixed operation is possible is whether or not the temporary operation can be performed for each shipping lot in the predetermined main storage 173 after the temporary storage is mixed with another shipping lot in the temporary storage 171 (possible = 1). (Not possible = 0) flag information. The plate-like product for which mixed operation is not possible (= 0) is not carried into the temporary storage 171 but directly into the main storage 173 of the corresponding shipping lot.

  As shown in FIG. 8, the stock status file 43 stores a product-specific status file 431 and a location-specific status file 433. FIG. 10 is a diagram illustrating a data configuration example of the product-specific status file 431. The product-specific status file 431 stores the stock status of plate products currently stored in the product storage area 17. Specifically, as shown in FIG. 10, the placement ID uniquely assigned to each of one or a plurality of temporary storage locations 171 and a plurality of main storage locations 173 constituting the product storage location 17 in the product status file 431. , The product category of the plate products stacked in the corresponding temporary storage site 171 or the main storage site 173, the shipping lot of the corresponding plate product, the plate thickness (mm), A width (m) and a length (m) are set and registered. In the storage section, whether the corresponding storage ID is the storage ID assigned to the temporary storage place 171 or the storage place ID assigned to the main storage place 173, that is, where the corresponding plate product is at present (temporary storage place) 171 or main storage 173; book / temporary) is set.

  FIG. 11 is a diagram illustrating a data configuration example of the placement-specific situation file 433. This placement-specific status file 433 stores the stock status of plate products currently stacked in the corresponding temporary storage location 171 or main storage location 173 for each of one or a plurality of temporary storage locations 171 and a plurality of main storage locations 173. To do. Specifically, as illustrated in FIG. 11, the placement-specific situation file 433 is associated with the placement ID, and the total of the plate-like products stacked in the corresponding temporary placement place 171 or the main place 173. The number of sheets, the total thickness of the plate products stacked in the corresponding temporary storage 171 or main storage 173 (the height of the mountain), and the plates stacked in the corresponding temporary storage 171 or main storage 173 The width of the product (if the storage section is “temporary”, the maximum width of the plate products stacked in the corresponding temporary storage 171) and the corresponding temporary storage 171 or the main storage 173 The length of the plate product (the maximum length of the plate products stacked in the corresponding temporary storage 171 when the storage section is “temporary”) is set and registered.

  Subsequently, as shown in FIG. 8, the placement operation support processing apparatus 3 reads and inputs the placement operation restriction file 45 from the database 4 and executes restriction input processing (step S3). FIG. 12 is a diagram illustrating a data configuration example of the location operation restriction file 45. This place operation restriction file 45 stores restrictions relating to the stacking of plate-like products with respect to the temporary place 171. Specifically, as shown in FIG. 12, the storage location operation restriction file 45 includes, for each of the items of the upper limit of the mountain height (mm) and the upper limit of the temporary storage days, the numerical values thereof, specifically, the mountain in the temporary storage 171. The upper limit height and the upper limit days of the temporary storage days used as the operation conditions of the temporary storage 171 are set and registered.

  Subsequently, as shown in FIG. 8, the site operation support processing device 3 executes a condition setting process as a condition setting unit (step S4). In this embodiment, since the temporary storage days 171 are used as the operating conditions of the temporary storage 171, in the process of step S 4, the temporary storage days upper limit is set by referring to the storage operation restriction file 45 input in step S 3. Set temporary storage days within the range that does not exceed the specified value. For example, the temporary storage days are set according to a user operation. Specifically, the storage site operation support processing device 3 transmits a message requesting the input of the temporary storage days to the terminal 5 to display the screen on the terminal 5 and is set as the temporary storage days upper limit in the storage site operation restriction file 45. The number of temporary days is received within a range (for example, 0 day to 4 days) that does not exceed a certain numerical value (4 days in the example of FIG. 12). The user operates the terminal 5 to input a desired temporary storage period. The input temporary placement days are transmitted to the placement operation support processing device 3, and the placement operation support processing device 3 sets the temporary placement days as operation conditions.

  Here, although the temporary storage days upper limit set in the storage location operation restriction file 45 is used as a restriction, the present invention is not limited to this. For example, the yard operation restriction file 45 includes a mountain height upper limit in which the upper limit height of the mountain in the temporary yard 171 is set as described with reference to FIG. Here, the maximum number of days that can be temporarily placed in the temporary storage 171 is determined from the upper limit of the mountain height and the number of plate-like products in a shipping lot that can be mixed and arrived at the product storage 17 every day. Therefore, the upper limit of the peak height may be used as a constraint, and the maximum temporary setting days may be calculated from the upper limit of the peak height, and the temporary setting days may be set as operating conditions within a range not exceeding the maximum temporary setting days. .

  Subsequently, the site operation support processing device 3 executes an operation simulation process with reference to the product information file 41 and the inventory status file 43 input in step S1, as operation simulation processing means, and is set as an operation condition in step S4. The loading and unloading of plate products in the temporary storage 171 and the main storage 173 are simulated according to the number of temporary storage days (step S5). Specifically, the storage site operation support processing device 3 temporarily places the plate-like product that arrives at the product storage site 17 in the temporary storage site 171 without exceeding the temporary storage days, and then places the plate-like product in the temporary storage site 171 into the main storage site. 173, and the actual inventory status of the temporary storage site 171 and the temporary storage site 173, which are changed by moving to 173 and placing them in each shipment lot, and shipping (shipping from the main storage site 173) on the scheduled shipping date, Calculate and obtain the number of moving sheets.

Here, for example, the occupation ratio is calculated for each main placement site 173 for each shipping lot in which the plate-like product temporarily placed in the temporary placement location 171 is placed according to the following equation (1). The average number of sheets in the main storage 173 is a value obtained by dividing the sum of the number of piles on the day in which the plate products of the corresponding shipping lot exist in each main storage 173 by the number of days in which the plate products of the corresponding shipping lot exist. It is. The maximum number of the main storage 173 is the maximum number that can be stacked in the corresponding main storage 173. If a peak height upper limit is set for each main storage 173, the maximum number of sheets is calculated and used from the peak height upper limit and the plate thickness of the plate-like product of the corresponding shipping lot. Further, the number of moving sheets is obtained by counting the number of plate products stacked in the temporary storage area 171 during the temporary storage days.
Average number of main storage 173 / maximum number of main storage 173 × 100 (1)

  After this operation simulation process, the site operation support processing apparatus 3 determines whether or not the operation condition needs to be changed. In the present embodiment, for example, it is determined whether or not the operation condition needs to be changed according to a user operation. Specifically, the storage site operation support processing device 3 first outputs to the terminal 5 as output means together with the occupancy rate and the number of movements acquired as a result of the operation simulation processing in step S5 together with the temporary storage days set as operation conditions in step S4. By transmitting, the screen is displayed on the terminal 5 and presented to the user. At this time, a message requesting selection of whether or not to change the temporary storage days, which is the operation condition, is also displayed on the screen, along with the temporary storage day change instruction, the temporary storage days within the range not exceeding the temporary storage days upper limit. Accept input. In response to this, the user confirms the presented occupancy ratio and the number of moving sheets, and examines whether or not the temporary storage days need to be changed. When it is determined that the temporary storage days need to be changed, the terminal 5 is operated to input the temporary storage days change instruction and the new temporary storage days are input.

  The temporary setting days change instruction and the temporary setting days input are transmitted to the placement operation support processing device 3, and the placement operation support processing device 3 determines that the condition needs to be changed (step S7: Yes). In this case, subsequently, the placement operation support processing device 3 executes a condition changing process, and changes the operation condition of the temporary placement 171 as the number of temporary placement days transmitted from the terminal 5 (step S9). Thereafter, the process returns to step S5, and the operation simulation process is executed again according to the changed temporary storage days.

  On the other hand, when there is no need to change the condition, that is, when the instruction for changing the temporary storage days is not input at the terminal 5 (step S7: No), the storage site operation support processing device 3 executes the result output process, The result of the operation simulation process performed in S5 is output to the database 4 and recorded as the operation instruction file 47 (step S11).

  FIG. 13 is a diagram illustrating a data configuration example of the operation instruction file 47. As shown in FIG. 13, the operation instruction file 47 includes a product ID, a planned shipping date, a destination code, a shipping lot, availability of mixed operation, a temporary storage location ID, and a temporary storage start date. It is the associated data table. The temporary placement place ID is set with the placement ID of the temporary placement place 171 used for temporary placement of the corresponding plate product. As the temporary placement start date, the date when the temporary placement of the corresponding plate product is started is set.

  As described above, according to the present embodiment, the future inventory status of the temporary storage 171 and the main storage 173 when a plate-like product that arrives at the product storage 17 is temporarily placed according to the number of temporary storage days set as the operation condition. Is obtained, and the occupation ratio of the temporary storage 171 and the main storage 173 and the number of moving sheets when the plate-like product temporarily placed in the temporary storage 171 is moved to the main storage 173 are acquired and displayed on the terminal 5 for example. Can be presented. Therefore, the user can use the temporary storage 171 and the main storage 173 that are necessary for storing the plate-like products that will arrive at the product storage 17 for each shipment lot, based on the expected congestion of the product storage 17 and the like. It is possible to determine the number of temporary storage days commensurate with the number of vacancies. According to this, it is possible to realize the operation of the temporary storage 171 corresponding to the stock situation necessary for storing the plate-like product that will arrive at the product storage in the future while considering the handling amount.

  In the above-described embodiment, the future inventory situation of the temporary storage 171 and the main storage 173 is predicted while changing the temporary storage days according to the user operation, and the occupation ratio and the number of moving sheets according to the temporary storage days are acquired. It was. On the other hand, the occupancy rate and the number of movements in each temporary storage day are acquired while automatically changing the temporary storage days within a range that does not exceed the numerical value set as the temporary storage day upper limit in the storage operation restriction file 45. You may do it. For example, in the example of FIG. 12, the upper limit of the temporary storage days is 4 days, so that the occupation ratio and the moving number of the temporary storage days are acquired while changing the temporary storage days from 0 days to 4 days. It may be. Alternatively, the numerical value set as the upper limit of the peak height is read from the storage operation restriction file 45, and the upper limit of the peak height and the number of plate-like products in the shipping lot that can be mixed and arrived at the product storage 17 every day in the future. Based on the determined maximum temporary storage days, the occupation ratio and the number of moving sheets may be acquired for each temporary storage days while changing the temporary storage days within a range not exceeding the maximum temporary storage days. In this case, for example, as illustrated in FIG. 7, a change in the occupation ratio or a change in the number of moving sheets with respect to each temporary storage day may be graphed and displayed on the terminal 5 on the screen and presented to the user. .

  Alternatively, a target value of the occupation ratio is set in advance, and only the occupation ratio and the number of moving sheets in the temporary storage days when the acquired occupation ratio value exceeds the target value are displayed on the terminal 5 and presented to the user. You may do it. The target value may be set as appropriate. For example, when the temporary placement using the temporary placement place 171 is not performed, that is, the value of the occupation rate when the temporary placement number is 0 days is used. In this case, for example, in the example of FIG. 7, the occupancy rate and the number of movements when the occupancy rate is higher than the line indicated by the alternate long and short dash line in FIG. The occupation ratio and the number of moving sheets when the number of days is 5 may be displayed on the terminal 5 and presented to the user.

  Similarly, the target value of the occupation rate is set in advance, and when the acquired value of the occupation rate does not exceed the target value, the temporary days are automatically changed (for example, lengthened), and the temporary value after the change is changed. You may make it acquire the occupation rate about the number of days to set, and the number of moving sheets. And when the value of the acquired occupancy rate exceeds the target value, the occupancy rate and the number of movements in the provisional days may be displayed on the screen of the terminal 5 and presented to the user.

  Further, not only the occupation rate but also a target value of the number of moving sheets is set in advance, and the occupation rate and the moving number of the temporary number of days that the acquired number of moving sheets does not exceed the target value are displayed on the terminal 5 on the screen. May be presented to the user. This target value may be set as appropriate. Similarly, a target value for the number of moving sheets is set in advance, and when the acquired number of moving sheets exceeds the target value, the temporary storage days are automatically changed (for example, shortened), and the temporary value after the change is changed. You may make it acquire the occupation rate about the number of days to set, and the number of moving sheets. Then, when the acquired value of the number of moving sheets does not exceed the target value, the occupation ratio and the number of moving sheets in the provisional days may be displayed on the terminal 5 and presented to the user.

  Further, in the above-described embodiment, the temporary storage days upper limit set in the storage operation restriction file 45 is used as a constraint, and the temporary storage days are set as operation conditions within a range not exceeding the temporary storage days upper limit. . On the other hand, as another constraint, it is possible to use the type of the shipping lot that can be mixedly operated or the upper limit of the number of shipping lots that can be mixedly operated. In this case, a corresponding numerical value may be set in the placement operation restriction file 45. Then, the shipment lot of the plate-like product temporarily placed in the temporary storage place 171 is limited, or the number of plate-like product shipment lots mixed in the temporary placement place 171 is restricted to temporarily place the plate-like product in the temporary placement place 171. You may make it perform. Then, shipment of a plate-like product that is temporarily placed in the temporary storage 171 as appropriate within a range not exceeding the corresponding numerical value, using the type of shipment lot that can be mixedly operated or the number of shipment lots that can be mixedly operated as the operation condition. While changing the type of lot or changing the number of shipment lots of plate products mixed in the temporary storage 171, an evaluation value indicating a future inventory situation such as an occupation ratio or an evaluation value indicating a handling amount such as the number of moving sheets You may make it acquire. Further, in addition to the above-mentioned temporary storage days, the type or number of shipment lots of the plate-like products temporarily placed in the temporary storage 171 are used as operational conditions, and future occupancy rates and the like based on these operational conditions are used. You may make it acquire the evaluation value showing handling amount, such as the evaluation value showing stock status, and the number of moving sheets.

  In the above-described embodiment, the number of moving sheets is exemplified as the evaluation value representing the handling amount. However, the time required for the corresponding handling operation may be calculated and used as the evaluation value representing the handling amount. For example, a time required for moving one plate-like product between the temporary storage 171 and the main storage 173 is set as a movement cycle time, and the handling work time obtained by multiplying the movement cycle time by the number of movements. May be used as an evaluation value representing the handling amount. In this case, an upper limit of the handling work time may be set in the placement operation restriction file 45. Then, in addition to the temporary days, the handling work time is further used as an operating condition, the temporary work days are appropriately changed within the range where the handling work time does not exceed the upper limit, and the temporary days are appropriately set within the range not exceeding the corresponding numerical value. You may make it acquire the evaluation value showing the amount of handlings, such as the evaluation value showing future inventory conditions, such as an occupation rate, and a moving number of sheets, changing.

  As described above, the storage operation support method and the storage operation support processing device of the product storage of the present invention take into account the handling amount and the temporary storage suitable for the stock situation necessary for storage of steel products that will arrive at the product storage in the future. It is suitable for realizing the operation.
