Description

  The present invention determines the location of parts by obtaining the production schedule, production line and number of production plans from the production plan when the parts used for product production are stored in the warehouse. In addition, the present invention relates to a part placement system that issues a part movement instruction, a part placement method, a part placement management program, and a computer-readable recording medium storing the part placement management program.

  In a factory with a large production volume that produces many types of products, various parts are loaded on plastic or wooden pallets every day, and are carried in large quantities to storage areas and warehouses in the factory.

  The parts brought into the factory are stored in the storage area and warehouse in the factory until they are used on the production day. In doing so, considering various conditions such as the number of parts and the size of the parts. It is necessary to arrange at a predetermined place, and in particular, it is desirable that a part used for production of a product currently in progress is arranged near a supply destination.

  One conventional example of a component placement system for placing components is to place components in consideration of physical distribution efficiency and area efficiency. As an example of this component placement system, there is a component placement support system disclosed in, for example, Japanese Patent Application Laid-Open No. 2004-18137. In this component placement support system, component points are set and supplied to each component based on two points: the priority determined based on the frequency of loading and unloading the component, and the area efficiency when placing the component on the site. Based on the two points of the transport distance from the previous point and the area where each place can be placed, a store point is set for each place, and the parts placement is calculated from these two points to determine the part placement.

Further, as another conventional example of the component placement system, the placement of the carried-in component is determined in consideration of the number of models produced using this component. As an example of this component placement system, there is a component placement system disclosed in Japanese Patent Laid-Open No. 10-338315. In this component placement system, for each component, a commonality indicating the number of models produced using the corresponding model is obtained, and a component with a higher commonality is located closer to the supplier, that is, a component with a high probability of being used. The calculation processing is performed so as to be placed near the supply destination.
JP 2004-18137 A JP 10-338315 A

  However, in the component placement support system disclosed in Patent Literature 1 and the component placement system disclosed in Patent Literature 2, the frequency of loading / unloading components, area efficiency, and whether or not the components are common parts between models. Since only priority is given, there are cases where parts that are not planned to be produced most recently are stored in a place near the supplier. As a result, there is a problem in that parts necessary for the currently produced model are arranged in a place far from the supplier. In addition, since the parts required for the model to be produced are not stored for each required part quantity, there is a case where the parts are crowded when the parts are carried out from the storage site. As a result, there is a problem that the conveyance efficiency is lowered.

  The most important thing in the transportation of parts is to reduce the transportation loss for production. For this purpose, it is necessary to always place the parts used for the model currently produced near the production place.

  Further, in the component placement support system disclosed in Patent Document 1 and the component placement system disclosed in Patent Document 2, it is possible to place the same type of parts together in a quantity that is used in one production. As a result, there is a problem in that it may be confusing when carrying out the parts during production.

  The present invention was devised to solve such problems, and its object is to provide a part placement system, a part placement method, a part placement management program, and a computer readable computer storing the part placement system that can reduce parts transportation loss. Is to provide a simple recording medium.

  In order to solve the above-described problems, the component placement system of the present invention stores a production plan storage unit 300 that stores a production plan, a component information database unit 100 that stores component information, and storage location information, as shown in FIG. Based on the placement information database unit 200, the part configuration table storage unit 400 that stores the production order, and the production plan, the part information, the placement information, and the production order, a part placement map that indicates the optimum placement position of the parts is created. Parts placement map creation means 500, parts placement map collation means 700 for collating the current part placement with the created part placement map, and moving the parts based on the collation results to make the placement always the optimum placement position And a component movement location calculation means 800 for issuing an instruction to move the component so that the movement amount of the component is minimized.

  According to such a configuration, the parts used for the current production (the production carried out closest) are carried out in order to supply the parts to the carry-out side (product production line) in the yard. Only the quantity required for production can be placed on the location side).

  Further, according to the present invention, the part arrangement map creating means is based on information indicating the production model and production amount constituting the production plan, and information indicating the number of parts and the number of parts constituting the part information. For each production (for example, production for one day), the types of necessary parts and the required amounts of various parts can be combined to obtain information on the parts group necessary for one production. In this case, it is possible to prevent a group of parts necessary for one production from being separately arranged in the storage area. Note that a plurality of parts constituting the part group may be stored in a pallet according to type, and at this time, the necessary amount is expressed by the number of pallets.

  In addition, the parts placement map creation means, based on the production schedule and information indicating the production line that constitutes the production plan and the placement information, the group of parts used for the production carried out most recently, The parts group that is placed closest to the supplier and used for the subsequent production may also be placed in the storage place in the order of the production plan. It can be placed on the unloading side of the storage site, and the parts can be supplied to the production line more smoothly. The parts used for production can be moved in a shorter time.

  In addition, the part arrangement map creating means further shows information indicating a production order constituting the part composition table and a part size constituting the part information with respect to the part group used for the production performed most recently. Based on the information, a detailed arrangement position may be determined by arranging a part having a large part size and a part having a distant place of use at a position closer to the supply destination in the place, in this case, Parts can be supplied to the production line more smoothly. Here, it is determined that the use place is farther as the production order is slower.

  Further, the part placement map creating means determines a detailed placement position for a part group used for the production performed most recently, and a detailed placement position for the part group used for the subsequent production. It is also possible to determine only the type and quantity of the parts constituting the parts group without determining, and in this case, the part arrangement map can be created in a shorter time.

  Further, the component arrangement map collating unit compares the component arrangement map created by the component arrangement map creating unit with the current component arrangement, and extracts a position where the arranged components do not match. In this case, the movement of the parts can be minimized.

  Further, when the component movement location calculation means instructs the movement destination of the component, a combination of the component to be moved and the position of the possible movement destination of the component is obtained, and the movement amount of all the combinations May be calculated and the moving destination of the component may be determined by selecting one combination that minimizes the moving amount. In this case, the component can be moved in the shortest time.

  Further, the part movement location calculation means may create a mobility calculation table showing the movement amounts of all combinations. In this case, the combination that minimizes the movement amount is made clearer. And the selection becomes easier.

  Further, the parts placement method of the present invention includes a production plan stored in the production plan storage unit, part information stored in the part information database unit, placement information stored in the placement information database unit, and part configuration table storage. Based on the production order stored in the department, the part placement map creation step for creating a part placement map that shows the optimum placement position of the part, and the part placement map matching for collating the current part placement with the created part placement map And a component movement location calculation step for instructing movement of the component so that the amount of movement of the component is minimized when the placement is always set to the optimum placement position by moving the component based on the collation result. Is.

  According to such a configuration, the parts used for the current production can be arranged in the quantity necessary for production on the carry-out side in the yard.

  In addition, in the part arrangement map creation step, each production unit is based on information indicating the production model and production amount constituting the production plan, and information indicating the number of parts and the number of parts constituting the part information. In addition, a step may be performed in which the types of necessary parts and the required amounts of various parts are collected to obtain information on a group of parts necessary for one production. In this case, a step necessary for one production may be performed. It is possible to prevent the parts group from being separately arranged in the storage area.

  Further, in the part arrangement map creation step, based on information indicating the production schedule and production line constituting the production plan and the placement information, a group of parts used for the production performed most recently is stored in the placement. Steps such as placing the parts closest to the supplier and placing them in the place in the order of the production plan may also be performed for the parts group used for the subsequent production. The parts can be arranged closer to the unloading side of the storage site, and the parts can be supplied more smoothly to the production line. Parts used for the production to be carried out can be moved in a shorter time.

  In addition, in the part arrangement map creation step, information indicating the production order constituting the part composition table and the part size constituting the part information are further shown for the part group used for the production performed most recently. Based on the information, a step may be performed in which a part with a large part size and a part with a distant place of use are placed closer to the supply destination in the place and a detailed placement position is determined. Can supply parts to the production line more smoothly.

  Further, in the part placement map creation step, a detailed placement position is determined for the part group used for the production performed most recently, and a detailed placement position is used for the part group used for the subsequent production. The step of determining only the type and quantity of the parts constituting the part group may be performed without determining the part group. In this case, the part arrangement map can be created in a shorter time.

  In the component placement map collating step, the component placement map created in the component placement map creating step is compared with the current component placement to extract a position where the placed components do not match. In this case, the movement of parts can be suppressed to the minimum necessary.

  Further, in the component movement location calculation step, when instructing the movement destination of the component, the combination of the component to be moved and the position of the possible movement destination of the component is obtained, and the movement amount of all the combinations And a step of selecting a combination that minimizes the amount of movement and determining a movement destination of the component may be performed. In this case, the component can be moved in the shortest time.

  Further, in the component movement location calculation step, a step of creating a mobility calculation table indicating the movement amounts of all combinations may be performed. In this case, the combination that minimizes the movement amount is more clearly defined. Can be made and the selection becomes easier.

  Furthermore, the part placement management program of the present invention causes a computer to execute each step of the part placement method described above, and according to such a configuration, the parts used for the current production can be carried out in the place. Only the quantity required for production can be placed on the side.

  Furthermore, the computer-readable recording medium of the present invention stores the above-described component arrangement management program, and according to such a configuration, the components used for the current production can be stored on the carry-out side in the storage site. Only the quantity required for production can be placed.

  According to the present invention, the parts placement is based on the production date, production model and production volume constituting the production plan, the size, number and quantity of parts constituting the part information, and the production order constituting the parts composition table. By creating a map, the amount of parts used in a single production can be grouped and placed in a part type, so the type and quantity of parts used in a single production can be easily determined. . In addition, since the parts used in current production can always be placed closer to the place where they are used, parts can be supplied to the production line while always realizing the shortest logistics lead. Parts transportation loss can be reduced. Also, among the parts group used for current production, the distribution efficiency is determined by determining the detailed placement position of each part in consideration of the part size, the number of parts, the number of parts, and the production order of the part composition table. Can be further improved.

  First, an embodiment of the component placement system of the present invention will be described.

  FIG. 1 is a configuration diagram of a component placement system of the present invention.

  The component placement system includes a component placement calculation unit 1000, a component information DB (database) unit 100 that stores data supplied to the component placement calculation unit 1000, a placement information DB unit 200, and a production plan storage. Unit 300 and a part configuration table storage unit 400.

  The component placement calculation unit 1000 includes a component placement map creation unit 500, a component placement map collating unit 700, and a component movement location calculation unit 800.

  The component arrangement map creating means 500 is a block that creates a map showing the optimum component arrangement according to production. The component arrangement map collating means 700 is a block for extracting a difference by collating the current arrangement of the component area with the created component arrangement map. The component movement location calculation unit 800 is related to component movement such as determining the component arrangement so that the movement of the component extracted by the component arrangement map collating unit 700 is the minimum movement in the result of calculating the mobility. It is a block that performs arithmetic processing (hereinafter also simply referred to as “component movement location calculation flow”).

  The part information DB unit 100 stores information on each part, for example, information indicating the model in which the part is used, the part size, the number of parts per pallet, and the number of parts used in one product. In addition, the storage location information DB section 200 stores information indicating the shape and layout of the parts storage space, and the place where the parts can be placed, and the production plan storage section 300 produces the models to be produced (production models). Information indicating a schedule (production date), a production line, and a production quantity (production quantity) is stored, and the parts configuration table storage unit 400 shows information indicating the order in which parts are used in production (usage order). Is stored.

  Next, an embodiment of the component placement method of the present invention implemented using the component placement system shown in FIG. 1 will be described.

  This component placement method is realized by the operations described later of the component placement map creating unit 500, the component placement map collating unit 700, and the component moving location calculating unit 800 shown in FIG.

  As described above, the component placement system according to the present embodiment includes the component placement map creating unit 500 indicating the optimum part placement according to the current production. First, an example of the operation of the component placement map creating unit 500 is described. Will be described.

  FIG. 2 is a flowchart showing an operation example of the component arrangement map creating means constituting the component arrangement system shown in FIG.

  First, in step S501, information indicating a production model (production model), a production schedule (production date), a production line, and a production number (production amount) is acquired from the production plan storage unit 300, and step S502 is obtained. From the parts information DB unit 100, the name of the part to be used (name of the part to be used), the part size, the number of parts per pallet and the number of parts to be used for one product are classified according to the model of the product to be produced. In step S503, the type of parts required for each production plan date and the required quantity of each part are calculated based on the acquired information. The quantity is expressed by the number of pallets.

  Subsequently, in step S504, the necessary part type for each production schedule date calculated in step S503 and the necessary quantity for each type expressed by the number of pallets are stored.

  In step S <b> 505, information indicating the shape and layout of the entire component storage area and the place where it can be arranged is acquired from the storage area information DB storage unit 200. Further, in step S506, the parts storage area is divided into areas for each area necessary for storing parts used for production on one production schedule date. This sorting process is performed in the order of the production plan dates stored in step S504, and the size of the necessary area is expressed by the number of pallets.

  Thereafter, in step S507, the head area is selected from the divided areas. In step S508, the parts stored in the head area are selected from the parts configuration table storage unit 400 for the parts to be produced. Information indicating the mounting order, that is, the production order is acquired.

  Next, in step S509, for the part stored in the head area, a part having a large part size and a smaller number of parts per pallet and a larger number of parts used for one product is obtained. Place it at the top of the area. If the number of parts per pallet is the same as the number of parts used for one product, the parts that are used farther in the line are placed at the head. Based on the production order acquired in step S508, the use place in this line is determined to be farther as the production order is slower.

  Finally, in step S510, an area storing parts related to production on the current day on which processing by the component arrangement map creating unit 500 is performed, and an area storing parts related to production on the next day, The two-day area is merged into one area, and the remaining areas are similarly merged into the two-day area into one area, and a parts placement map showing information about these merged areas. And finishes the process.

  Next, operation examples of the component arrangement map collating unit 700 and the component movement location calculating unit 800 will be described.

  FIG. 3 is a flowchart showing an example of the operation of the component movement location calculation means constituting the component placement system shown in FIG. Note that steps S801 and S802 in the figure are performed by the component arrangement map collating unit 700, and steps S803 to S821 are performed by the component movement location calculating unit 800.

  First, in step S801, the component placement map created by the component placement map creating means 500 is collated with the current component placement. This current part placement is obtained from the information obtained by removing the part pallet used for production during the creation of the current part placement map from the previous part placement map from the previously created part placement map. .

  Subsequently, in step S802, all the pallets in which the arrangement indicated by the created component arrangement map and the arrangement indicated by the current component area do not match are registered in the component movement list.

  Furthermore, since the part used for the production performed most recently has to be arranged in the head area of the parts place, the head area is set as a part movement destination in step S803.

  In step S804, it is determined whether all pallets registered in the part movement list are arranged in the area currently set as the movement destination.

  If all the pallets are arranged in the area set as the movement destination (if the determination result in step S804 is YES), the process proceeds to step S812 described later. On the other hand, if not all pallets have been arranged yet (if the determination result in step S804 is NO), the process proceeds to step S805.

  In step S805, it is determined whether or not the parts movement list is empty (there is no pallet registered in the parts movement list). If the component movement list is empty (when the determination result in step S805 is YES), the component movement location calculation flow ends. On the other hand, if the parts movement list is not yet empty (if the determination result in step S805 is NO), the process proceeds to step S806.

  In step S806, the amount of movement when the pallet registered in the part movement list is moved from the current part placement position to the position indicated by the part placement map created by the part placement map creating unit 500 is calculated as the mobility. This calculation of the movement amount is performed for all the component pallets on which the same component is loaded.

  Subsequently, in step S807, a pallet with the smallest calculated mobility is selected from the pallets, and at the same time, information indicating the movement destination of this pallet (the position indicated by the component arrangement map created by the component arrangement map creating unit 500). Are also read out, and the movement of the selected pallet is instructed in step S808.

  In step S809, the selected pallet is deleted from the parts movement list, and in step S810, the parts placement map is updated to indicate that the place of the selected pallet has been changed to the current place as the movement destination. Further, in step S811, the component arrangement map is updated so as to indicate that the place where the moved pallet was originally based is empty.

  Thereafter, the process returns to step S804, and all the pallets are arranged in the area set as the movement destination (the determination result in step S804 is YES), or the parts movement list is empty (determination in step S805). Steps S804 to S811 are repeated until the result is YES. When the parts movement list becomes empty (when the determination result in step S805 is YES), the parts movement location calculation flow ends. On the other hand, when all the pallets are arranged in the area set as the movement destination (when the determination result in step S804 is YES), the process proceeds to step S812, and the movement destination is set to the next area.

  Subsequently, in step S813, it is determined whether all pallets registered in the part movement list are arranged in the area currently set as the movement destination.

  If all the pallets are arranged in the area set as the movement destination (if the determination result in step S813 is YES), the process proceeds to step S814 described later. On the other hand, if all the pallets are not yet arranged (if the determination result in step S804 is NO), the process proceeds to step S815.

  In step S814, the destination is set to the next area. In a succeeding step S815, it is determined whether or not the parts movement list is empty (a state in which there is no pallet registered in the parts movement list). If the component movement list is empty (when the determination result in step S815 is YES), the component movement location calculation flow ends. On the other hand, if the parts movement list is not yet empty (if the determination result in step S815 is NO), the process proceeds to step S816.

  In step S816, the movement amount when the pallet registered in the part movement list is moved from the current part arrangement position to the position indicated by the part arrangement map created by the part arrangement map creating unit 500 is calculated as the mobility. This calculation of the movement amount is performed for all the component pallets on which the same component is loaded. Here, since the movement destination is not the head area, the movement destination to arrange the pallet is not determined in detail.

  Subsequently, in step S817, a pallet with the smallest calculated mobility is selected from the pallets, and at the same time, information indicating the movement destination of this pallet (the position indicated by the component arrangement map created by the component arrangement map creating means 500). Are also read out, and the movement of the selected pallet is instructed in step S818. In step S819, the selected pallet is deleted from the parts movement list, and in step S820, information regarding the location of the selected pallet is deleted from the part placement map. In step S821, the moved pallet is based on the original. The parts placement map is updated to indicate that the place is empty.

  Thereafter, the process returns to step S813, where all the pallets are arranged in the area set as the movement destination (the determination result in step S813 is YES) or the parts movement list is empty (determination in step S815). Steps S813 to S821 are repeated until the result is YES. When the parts movement list becomes empty (when the determination result in step S815 is YES), the parts movement location calculation flow ends. On the other hand, when all the pallets are arranged in the area set as the movement destination (when the determination result in step S813 is YES), the process proceeds to step S814, and the movement destination is set to the next area. .
