Description

  The present invention relates to a technique for creating a production plan in a plant having multi-stage production facilities while considering production conditions peculiar to each facility.

  In recent years, various methods have been provided for creating a production plan for manufacturing a product in a plant having a manufacturing process depending on the business condition of the manufacturing industry.

  In particular, not only to create a production plan for a single plant, but to optimize and streamline the flow of parts from parts procurement to product production, finished product logistics and inventory, and supply to consumers. Therefore, a method of simultaneously creating parts and raw materials between factories and distribution bases, a transportation plan for finished products, and an inventory placement plan for distribution bases has been proposed (for example, see Patent Document 1).

JP 2012-88784 A

  However, according to the production plan creation method described in Patent Document 1, it is possible to optimize and improve the efficiency of the entire supply chain, but the accuracy of the production plan in the plants constituting this supply chain is improved. That must also be considered.

  In particular, when creating a production plan in a plant equipped with multi-stage process equipment, a plan is often created based on the required amount of each product, but the plan must be created taking into account the constraints specific to the process equipment. Cases often exist.

  For example, in a manufacturing process in which a product is processed by pressurization, a shipped product or an intermediate product is manufactured while changing the pressure in the system. It is necessary to create a linked production plan.

  In other words, when planning, it is necessary to consider not only the production plan / product inventory status along the time axis in each process but also the constraint conditions according to the state of the production equipment, which increases the burden on the planner. ing.

  In particular, in this case, the production plan of the target product is often created based on the experience and intuition of the person in charge, and if the manufacturing process is linked to multiple stages, the target of the plan becomes enormous and the workload is very high. Long-term planning will be difficult.

  As a result, the optimization of the micro-plan rather than the optimization of the macro-plan is planned, and the overall plan may be inefficient. Other processes are also affected, resulting in a plan review of the entire process, resulting in a problem that the planned load tends to be high.

  Therefore, in the present invention, in creating a production plan having a multi-stage process, a production plan automatic creation device and a production plan that can efficiently create a production plan while taking into account the constraint conditions specific to each process facility An object is to provide an automatic creation system, a control method, and a program.

  FIG. 1 is a system configuration diagram showing an example of the configuration of a production plan creation support system of the present invention.

FIG. 1 is a configuration diagram showing a schematic configuration of a system in the production plan creation support system 100.
The production plan creation support system 100 has a configuration in which one or a plurality of client terminals (such as personal computers and input / output devices) 102 and one or a plurality of data servers 104 are connected via a network 106.

  FIG. 2 is a functional block diagram showing a functional configuration of the data server 104 of FIG.

  In FIG. 2, reference numeral 201 denotes a CPU that comprehensively controls each device and controller connected to the system bus 204. Further, the ROM 202 or the external memory 211 is necessary to realize a BIOS (Basic Input / Output System) or an operating system program (hereinafter referred to as an OS), which is a control program of the CPU 201, or a function executed by each server or each PC. Various programs to be described later are stored.

  A RAM 203 functions as a main memory, work area, and the like for the CPU 201. The CPU 201 implements various operations by loading a program or the like necessary for execution of processing from the ROM 202 or the external memory 211 into the RAM 203 and executing the loaded program.

  An input controller 205 controls input from a keyboard (KB) 209 or a pointing device such as a mouse (not shown). A video controller 206 controls display on a display device such as a CRT display (CRT) 210.

  In FIG. 2, although described as CRT 210, the display device is not limited to the CRT, but may be another display device such as a liquid crystal display. These are used by the administrator as needed.

  Reference numeral 207 denotes a memory controller, which is installed in an external storage device (hard disk (HD)), flexible disk (FD), or PCMCIA card slot for storing a boot program, various applications, font data, user files, editing files, various data, and the like. Controls access to an external memory 211 such as a compact flash (registered trademark) memory connected via an adapter.

  A communication I / F controller 208 is connected to and communicates with an external device via a network (for example, the network 106 shown in FIG. 1), and executes communication control processing on the network. For example, communication using TCP / IP is possible.

  Note that the CPU 201 enables display on the CRT 210 by executing outline font rasterization processing on a display information area in the RAM 203, for example. In addition, the CPU 201 enables a user instruction with a mouse cursor (not shown) on the CRT 210.

  Various programs to be described later for realizing the present invention are recorded in the external memory 211 and executed by the CPU 201 by being loaded into the RAM 203 as necessary. Furthermore, definition files and the like used when executing the program are also stored in the external memory 211, and detailed descriptions thereof will be described later.

  Note that the hardware configuration of the client terminal 102 is substantially the same as the configuration of the data server 104, and therefore description thereof will be omitted. Hereinafter, description will be made using the same reference numerals.

  FIG. 3 is a schematic diagram of a product manufacturing sequence of a plant having a multi-stage process facility.

  In the order from left to right in the figure, the product (shown by △) is processed at each process (shown by □), and the product at the right end becomes the final shipment product. At each process equipment, one or more raw materials (input products) ), One or a plurality of products are manufactured, and a multi-stage process facility is provided. Therefore, a product in a specific process facility may be a raw material in the next process.

  In FIG. 3, when each process equipment, raw material and product are considered as nodes, and the relationship between input and production is regarded as a branch, this product manufacturing order can be viewed as a directed graph (hereinafter, this product manufacturing order directed graph is referred to as a production network). Call it.)

  In this production network, the flow from the procured raw material to the final shipment product direction is called an extrusion direction, and the flow from the final shipment product to the procured raw material direction is called a retroactive direction.

  For example, in assembly manufacturing, the relationship between the raw materials and products produced in this process equipment is managed using a bill of materials (BOM), which is a product (main product / This is a table for managing product-specific information such as composition of raw materials), composition of raw materials, usage ratio of products / raw materials, composition information of raw materials, production lead time, etc. for each product.

Hereinafter, FIG. 4, reference to FIG. 5, an example of process equipment specific稼dynamic conditions.

  FIG. 4 is a diagram showing changes in manufacturable items depending on the operating conditions of the process equipment. The operating conditions may be regarded as a mechanical setting value of the process equipment or a physical index value.

  For example, when the product is processed with the pressure changed as the operating condition, the products A and B can be manufactured in the state of the pressure α in FIG. 4, and the product A cannot be manufactured by reducing the pressure β. When B and C can be manufactured and the pressure γ is set, the products A, B, and C cannot be manufactured, while the products D and E can be manufactured.

  FIG. 5 is a diagram showing process equipment in consideration of the reuse of by-products. By-products are products that are produced at the same time in products other than the intended product ( Corresponding to scrap during production).

  In FIG. 5, the process equipment 1 uses the raw material O to produce the product P and the by-product Q, and the process equipment 2 produces the product S using the by-product Q generated at this time and the separately prepared raw material R. The by-product Q is a raw material when viewed from the process equipment 2.

  Since the by-product Q is used for manufacturing the product S, when the product S is produced, it is necessary to always consider the stock status of the by-product Q. This means that the production status of the by-product in the previous process is the rate-limiting condition for the product S.

  Here, when the product (including by-products) of a certain process equipment is the raw material of another process equipment, the process equipment that manufactures the relationship between the two process equipment as a product is manufactured as the upper process and the raw material. The process equipment that performs this process is called the lower process. In the example of FIG. 5, the process facility 1 is an upper process as viewed from the process facility 2, and the process facility 2 is a lower process as viewed from the process facility 1.

  Hereinafter, the flow of the production plan automatic creation system in the present embodiment will be described.

  In FIG. 6, the production plan automatic creation process will be described. In the present embodiment, this process is executed after the user gives an instruction to execute a process for automatically creating a production plan using the production plan screen of FIG.

  The production plan screen 300 obtains a production plan from the start time to the end time from the start time 301, end time 302, and production table (FIG. 16) for creating an automatic plan, and displays it in a production plan display selection area 307 (described later). Display button 303 to be pressed when performing, automatic plan button 304 to be pressed when executing the production plan automatic creation process, backward category 305 for selecting when creating a production plan in the backward direction, production in the pushing direction A push section 306 for selecting when creating a plan, a production plan at a target time is displayed, a process facility to be subject to automatic planning, a production plan display selection area 307 for selecting a time, and a change in the production plan A time fence 308 representing the earliest possible time is provided.

  Since the time fence is generally set up to the most recent fixed instruction plan portion, it is often set at a time obtained by adding a fixed period to the final production result time. In the example of FIG. 19, since the time fence is set at the position of time 2, the production plan up to time 1 cannot be changed, and the production plan after time 2 can be changed.

  In the example of FIG. 19, the time and process equipment corresponding to the selected cell in the production plan display selection area 307 on the production plan screen are the start time and the process equipment that is the starting point, and the end time is the end time of the display target time. The retro / extrusion category is based on the selection of the retro / extrude radio button in the production plan screen. The time fence is given as a final time when the plan cannot be overwritten, with a final value added with a fixed value.

  As a premise of this production plan automatic creation process, the entry / exit information of each item based on the receipt / shipment information needs to be registered. This means that, for each record in the receipt / shipment table (see FIG. 17) when the system is started, a receipt record corresponding to the receipt record and a delivery record corresponding to the shipment record are registered in the receipt / shipment inventory table (see FIG. 18). Just keep it.

  The receipt / shipment table shown in FIG. 17 includes a target time for identifying the timing of receipt / shipment occurrence, an item code for uniquely identifying the target item, a receipt / shipment category for identifying receipt or shipment, and a receipt source. Alternatively, it has a receipt / shipment destination and a quantity of receipt / shipment for identifying the shipment destination, and stores and manages information on the amount of receipt / shipment generated at each time.

  The entry / exit inventory table shown in FIG. 18 is used to identify the target time for identifying the occurrence or change timing of the entry / exit inventory, the item code for uniquely identifying the target item, receipt, delivery, and inventory. It has storage / inventory classification, quantity of storage / inventory inventory, and stores and manages information on the amount of storage / inventory and the amount of inventory at each time.

  In step S101, a process equipment table (FIG. 9), an item table (FIG. 10), a product constituent main product table (FIG. 11), a product constituent raw material table (FIG. 12), and a product constituent byproduct table (FIG. 13) are used. And build a production network.

  The process equipment table shown in FIG. 9 includes a process equipment code and a process equipment name for uniquely identifying a manufacturing process, and stores and manages information on the process equipment used for production planning.

  The item table has an item code for uniquely identifying a manufactured item, an item name, and a manufacturing priority order that is a priority order at the time of manufacturing, and stores and manages information on items used for production planning.

  The product configuration main product table shown in FIG. 10 includes a process equipment code for uniquely identifying a manufacturing process, a main product item code for uniquely identifying a main product to be manufactured, and the maximum production per unit time of the main product. It has a production upper limit that defines the quantity, and stores and manages information on items that can be produced in each process facility and the maximum production volume per unit time.

  The product component raw material table shown in FIG. 11 is a process equipment code for uniquely identifying a manufacturing process, a main product item code for uniquely identifying a main production target item, and a material for uniquely identifying a material as a raw material. It has a usage amount that defines the amount of raw material items necessary to produce one unit quantity of the item code and main item, and stores and manages information on the required amount of each raw material item for the items produced at each process facility. doing.

  The product composition by-product table shown in FIG. 12 uniquely identifies a process equipment code for uniquely identifying a manufacturing process, a main item code for uniquely identifying a main product to be manufactured, and an item that is a by-product. It has an item code for identifying, and a production volume that defines the amount of by-product produced when producing one unit of main product. For each item produced by each process equipment, Stores and manages information on simultaneous production.

  Specifically, records that exist in the process equipment table and records that exist in the item table are nodes, respectively, and correspond to the main product item code from the node that corresponds to the process equipment code of each record that exists in the product component main product table. Put a directed branch to the node.

  Subsequently, a directional branch from the node corresponding to the item code of each record existing in the product component raw material table to the node corresponding to the process equipment code is extended, and finally, each record existing in the product component byproduct table is recorded. A directional branch is extended from the node corresponding to the process equipment code to the node corresponding to the item code. Thereby, a production network can be constructed.

  In step S102, ordering is performed on each node of the production network constructed in step S101. Since the production network is a directed graph, the total order relationship between the nodes can be set by topological sorting.

  By carrying out this ordering, the plan creation order of each process facility in automatic production plan creation becomes clear. By performing the sorting in this step, if there is a relationship between the upper process and the lower process between the two processes due to the nature of the topological sort, the upper process is always assigned a lower order. For example, in the case of an extrusion plan, a plan is always made in the order from the upper process to the lower process, and therefore the plan may be created in ascending order of this order.

  By using this method, even if there is no clear planning order between process facilities and a vertical relationship between process facilities, an order relationship and a vertical relationship between process facilities can be set.

  The production network can be constructed by using a known method, and the order relationship can be determined by setting an effective branch or the like.

  However, the topological sort is based on the premise that there is no directed cycle, so if there is a directed cycle, the branches in the cycle are deleted as preprocessing, or ordering is performed using depth-first search, etc. You can set the total order relation by the method.

  Hereinafter, step S103 to step S104 are executed in order of sorting from the process facility as the starting point for each process facility in the topologically sorted production network.

  In step S103, the process facility currently being processed, the plan start time, and the plan end time are input, and the process facility production plan process (detailed later) is executed.

  In step S104, the process equipment to be the next processing target is acquired in the sort order in step S102. At this time, if the retroactive plan is selected, the process equipment in the upper process direction is acquired from the current process equipment, and if the extrusion plan is selected, the process equipment in the lower process direction is acquired from the current process equipment. .

  In FIG. 7, the process facility production planning process will be described. The process facility production plan process is executed in step S103 of the production plan automatic creation process. As the input of this process, the target process equipment, the start time and the end time of the plan are given.

  In the process facility production planning process, the following steps S201 to S207 are executed for each product to be manufactured in the corresponding process.

  At this time, the target product is searched from the product component main product table (FIG. 11) for a record whose process equipment code matches the process equipment to be processed, and is set as an item corresponding to the main product code. The execution order is set in ascending order of the manufacturing priority order in the item table (FIG. 10).

  Thereafter, in this process, step S201 to step S207 are executed for each plan time from the plan start time to the end time. In the retroactive plan, it is executed in the descending order of time, and in the push-out plan, it is executed in the ascending order of time.

  In step S201, the operation conditions of the target process are acquired at the target time and the adjacent time, that is, the time obtained by subtracting 1 from the target time and the time obtained by adding 1 to the target time.

  Note that if the operating condition is set at the target time in step S205, the corresponding operating condition is acquired.

  In this step, when the target time is the start time or the end time, the process equipment code is the process equipment code to be processed from the production table (see FIG. 16), and the time From is the time obtained by subtracting 1 from the start time (end time If the corresponding record exists, the operation condition of the corresponding record is found. The record is searched for a time equal to or less than the time obtained by subtracting 1 from the start time (the time obtained by adding 1 to the end time). Get the code. If the record does not exist, leave it empty.

  The production table shown in FIG. 16 includes a time From identifying the production start time, a time To identifying the production end time, a process equipment code for uniquely identifying the manufacturing process, and an operating condition for uniquely identifying the operating condition. Code, production item code for uniquely identifying the item to be produced, production volume that defines the production volume per unit time, and information on production items and production volume at each time and each process facility I manage.

  In step S202, a required product amount (inventory amount) is acquired. In the retroactive planning, the required amount is the amount of product used in the lower process at each time, that is, the amount of product delivered and the production lead time.

  In other words, when the output amount of the target product at time t is x and the production lead time is L, the required product amount at the time obtained by subtracting L from time t is x. On the other hand, in the extrusion plan, the stock amount of the raw material of the target product at the corresponding time is acquired.

  For the quantity of goods to be delivered and the quantity of raw materials in stock at each time, use the warehousing / delivery inventory table (FIG. 18), and if the item code matches the corresponding item, If so, it is only necessary to search for a record that has a storage / exit category.

  In step S203, it is determined whether production has already been set at the target time. Note that determining the production setting determines whether or not a production plan for the process equipment to be processed at the target time has been established.

  Here, “planned” means that a production plan corresponding to the target time and process equipment to be processed exists in the production table, or that the target time on the memory and the plan of the process equipment to be processed have been set in step S206. If so, plan it.

  Specifically, if the process equipment code in the production table matches the process equipment to be processed and there is a record whose target time is greater than or equal to time From and less than or equal to time To, it is determined that production has already been set and the process proceeds to step S207. . If the target time in the memory and the plan for the target process facility have already been set in step S206, it is determined that production has already been set, and the process proceeds to step S207.

  If there is no production setting on the record and the memory, the process proceeds to step S204. In step S204, it is determined whether the current target product can be produced by changing the operation condition or the operation condition at the target time. .

  Specifically, in the operating condition table (see FIG. 14), when there is no operating condition in the process equipment to be processed, all items can be produced without operating conditions.

  The operation condition table shown in FIG. 14 is a list of operation condition codes for uniquely identifying manufacturing processes, operation condition codes for uniquely identifying operation conditions, and operation condition codes that can be directly shifted from the operation condition codes of the corresponding record. The operation condition code that can be transitioned is provided, and the operation condition that can be set in each process facility and the information on whether or not to allow transition between each operation condition are stored and managed. In the example of FIG. 14, a plurality of operation conditions that can be transitioned to a transitionable operation condition code are registered with | symbols.

  The operating conditions are, for example, equipment and equipment standards for manufacturing a specific product in the assembly industry, and the transition of operating conditions corresponds to setup change, while in food processing, etc., it corresponds to processing conditions. .

  As a specific example, the frying temperature of food is mentioned. For example, even when the food K and the food L that are fried in the same manufacturing process equipment are manufactured, if the temperature at which the food K is fried is different from the temperature at which the food L is fried, the manufactured product is changed from the food K to the food L. In this case, the frying temperature, which is the operating condition, must be changed.

In other words, in this step, by changing the稼dynamic conditions, is carried out producible determined whether or not the products.

  If operating conditions exist, use the manufacturable item table by operating conditions (see Fig. 15), search for records where the process equipment code matches the target process equipment, and the manufacturable item code includes the production target item, Get a list of applicable operating condition codes.

  The manufacturable item table by operating condition shown in FIG. 15 includes a process equipment code for uniquely identifying a manufacturing process, an operating condition code for uniquely identifying an operating condition, a process equipment code of a corresponding record, and a manufacturable item. Manufacturable item codes that define a list of items are stored, and information on items that can be manufactured under specific operating conditions in each process facility is stored and managed. In the example of FIG. 15, a plurality of manufacturable items are registered in the manufacturable item code with a | symbol as a separator.

  The reason why such processing is performed will be described along with a specific example using the example of the previous food.

  Consider the case where food M exists in addition to food K and food L. Here, the operating conditions are the same frying temperature as before, that is, a different frying temperature.

  It is assumed that the frying process of the food M can be processed without any problem in quality, either the frying temperature of the food K or the frying temperature of the food L. In this case, food K and food M can be manufactured at the frying temperature of food K, and food L and food M can be manufactured at the frying temperature of food L.

  When the food L is processed at time t, it is not necessary to change the frying temperature when the food M is manufactured at time t + 1. On the other hand, when manufacturing food K at time t + 1, it is necessary to change the frying temperature to the frying temperature of food K.

  In this step, if the operating condition at the target time acquired in step S201 is not empty, it is determined whether it is included in the operating condition code acquired from the manufacturable item table by operating condition. If it is included, it is determined that production is possible and the process proceeds to step S205.

  Further, in this step, if the operation condition at the target time acquired in step S201 is empty, it is determined whether or not the operation condition before and after the target time acquired in step S201 can be changed to an operation condition that can be produced.

  If the operating conditions before and after the target time are both empty, it is determined that transition is possible and the process proceeds to step S205.

  On the other hand, if one or both of the operating conditions before and after the target time are not empty, use the operating condition table, the process equipment code matches the process equipment to be processed, and the operating condition code matches the operating conditions before and after the target time. The record is searched, and it is determined whether or not the transitionable operation condition code is included in the operation condition code acquired from the manufacturable item table by operation condition.

  At this time, it should be noted that it is necessary to be able to transition from both the time immediately before and the time immediately after the target time.

  In step S204, stock determination of raw material items is performed only at the time of the extrusion plan. Specifically, a record in which the process equipment code matches the process equipment to be treated and the production item code matches the item code of the product to be processed in the product component raw material table (FIG. 12) Get a list of and usage.

  For each acquired raw material item, the inventory quantity is searched using the storage / inventory inventory table. If the acquired inventory quantity is less than the usage amount of the corresponding raw material item, it is determined that production is impossible, and step The process proceeds to S207, and if production is possible, the process proceeds to step S205.

  In addition, the maximum production upper limit of the record where the stock quantity / usage amount of each raw material item and the process equipment code in the product component main product table match the process to be processed and the production item code matches the production target item is It will be the quantity that can be produced at the time.

  In step S205, when the transitionable operation condition determined in step S204 exists, the operation condition at the target time is set as the corresponding operation condition.

  On the other hand, if the operation condition is empty before and after the target time, the operation condition that can produce the largest number of the operation conditions at the target time that can be produced by the production target item searched in step S204. Set the condition.

  In step S206, the process equipment to be processed, the target time, and the target manufactured item are input, and the production setting process (described later in detail) at the corresponding time is executed.

  In step S207, in the retroactive plan, the requested amount set at the current time is carried forward and added to the previous time. Do nothing in the extrusion plan.

  After executing Step S201 to Step S207 for each product to be manufactured and time, production setting of the process equipment to be processed is performed in Step S208. On the memory, the production information set for each discrete time in step S206, that is, information on production items, production quantities and operating conditions at each time, each process facility is merged and inserted into the production table. Inserting goods receipts / inventories and inventory fluctuations in production into the goods receipt / exit inventory table.

  Specifically, the production at the current time and the next time are compared in order from the start time to the end time of the plan, and if the production item, operating condition, and production volume match, the production is merged, and the production item, operating condition, and If any of the production quantities is different, use the production that has been merged so far, use the time From as the merge start time, the time To as the merge end time, the process equipment code as the target process equipment code, the production item, operating conditions, and production volume. And insert it into the production table.

  Further, production related items in each production are acquired in order from the start time to the end time of the plan. For the by-products that can be acquired using the production item and product component by-product table (FIG. 13), the warehousing amount is set.

  In the product component by-product table, the process equipment code whose process equipment code is the processing target and the record whose production item code is the target production item are searched, and the by-product product item is acquired from the item code field.

  For the production item and each by-product item, the receipt and stock at each time are calculated. For production items, the production amount set in step S206 is the amount of goods received at each time. For by-product items, the production amount of the production item is multiplied by the production amount in the corresponding record of the product by-product table. The produced amount becomes the amount of goods received at each time.

  For the inventory quantity of production items and by-product items, search the records where the target time is the time obtained by subtracting 1 from the corresponding time, the item code is the corresponding item, and the input / output / stock category is Is acquired as the immediately preceding inventory quantity.

  Further, a record in which the target time is the corresponding time, the item code is the corresponding item, and the input / output / inventory category is retrieved from the storage / inventory inventory table is acquired as the output amount at the corresponding time.

  From the acquired and calculated inventory quantity immediately before and the warehousing quantity and delivery quantity at the corresponding time, the inventory quantity at the corresponding time adds the warehousing quantity at the target time to the previous inventory quantity, and the value obtained by adding the warehousing quantity at the target time It can be calculated by subtracting the amount of goods issued.

  From the warehousing amount and the inventory amount obtained in this way, the production item at the corresponding time and the warehousing and inventory record of each by-product item are created. Record is the target time at the target time, the item code is the item code of the production item or each by-product item, the receipt / inventory category is receipt for receipt, it is present for inventory, and the quantity is obtained first Set the amount of goods received or stock quantity and insert.

  On the other hand, for raw materials, search the product component raw material table for records where the process equipment code is the target process equipment code and the production item code is the target production item, and obtain the raw material item from the item code field. To do.

  For each raw material item, issue and stock at each time are calculated. For the raw material item, the value obtained by multiplying the production amount of the production item by the usage amount in the corresponding record of the product constituent raw material table is the outgoing quantity at each time.

  For the stock quantity of the raw material item, search the record with the target time subtracting 1 from the corresponding time from the entry / exit inventory table, the item code is the corresponding item, and the inventory / inventory classification is present, and the quantity is the inventory immediately before Get as a quantity.

  Further, a record in which the target time is the corresponding time, the item code is the corresponding item, and the input / output / inventory classification is input is retrieved from the storage / inventory inventory table and acquired as the output amount at the corresponding time.

  From the acquired and calculated inventory quantity immediately before and the warehousing quantity and delivery quantity at the corresponding time, the inventory quantity at the corresponding time is calculated by adding the warehousing quantity at the target time to the previous inventory quantity. It can be calculated with the subtracted value.

  From the output amount and the stock amount obtained in this way, the output and stock records of the raw material items at the corresponding time are created. The record is the corresponding time at the target time, the item code is the item code of the raw material item, the entry / exit / inventory classification is output when the issue is issued, it is present when it is in stock, and the quantity is the previously obtained issue quantity or inventory quantity Set and insert.

  In the present embodiment, the manufacturing priority order of the item table is used as the priority order of manufacturing items in each process facility, but this may be replaced with another index. For example, priority is given to an item with a small product inventory at a certain point in time / a large amount of raw material inventory, and a method of giving priority to a manufactured item with a small production condition that can be manufactured.

  Sorting by the number of manufacturable operating conditions is when the process equipment code of the manufacturable item table by operating condition matches the process equipment to be processed, and a record containing the corresponding item in the manufacturable item code is searched. Priority is given to manufactured items that have a search result that is not zero and has a small number of records.

  In FIG. 8, the production setting process at the target time will be described. This process is executed in step S206 in the process facility production planning process (FIG. 7). As the input of this process, process equipment to be processed, target time, and target manufactured item are given.

  In step S301, the operating condition of the process equipment to be processed at the target time is acquired. If the operating condition is set in step S205, the corresponding operating condition is acquired. If the operating condition is not set, the corresponding operating condition is acquired in the same manner as in step S201.

  In step S302, a required product amount (inventory amount) is acquired by the same procedure as in step S202.

  In step S303, it is determined whether or not a by-product is included in the production of the corresponding product. In the retroactive plan, the product component by-product table (FIG. 13) table is used to search for a record in which the process equipment code matches the process equipment to be processed and the production item code matches the target production item. If there is even one, the by-product is included in the raw material of the target product, and the process proceeds to step S304. Otherwise, the process proceeds to step S307.

  In the extrusion plan, the product component raw material table (FIG. 12) is used to search for records whose process equipment code matches the process equipment to be processed and whose production item code matches the manufacturing item to be processed. Get a list of item codes.

  Subsequently, using each item code of the raw material item list, a record in which the item code in the product component by-product table (FIG. 13) matches the item code of the corresponding raw material item is searched. If there is even one corresponding record, the by-product is included in the raw material of the product to be processed, and the process proceeds to step S304. Otherwise, the process proceeds to step S307.

  In step S304, the stock of the corresponding by-product item acquired in step S303 is acquired. For this purpose, a receipt / inventory inventory table (FIG. 18) is used to search for records where the item code is the corresponding by-product item code and the receipt / exit / inventory classification is at the target time, and the corresponding quantity is acquired as the inventory quantity. .

  In step S305, it is determined whether the by-product stock is sufficient. In the retroactive planning, if the corresponding by-product item inventory is excessive, it is determined that production is impossible and the process proceeds to step S306. In the case of the extrusion plan, if the corresponding by-product item inventory is insufficient, it is determined that production is not possible. Proceed to step S306, otherwise proceed to step S307.

  In step S306, the requested amount is carried forward to the previous time in the same procedure as in step S206. As in step S207, nothing is done in the case of an extrusion plan.

  In step S307, the target manufacturing item can be produced at the target time, and the production target time, the production target item, the operating condition, and the production amount are held in the memory.

  Here, in the case of the retroactive plan, the production volume is the smaller of the production upper limit of the record corresponding to the process equipment to be processed and the production item using the requested quantity at the relevant time and the product component main product table (FIG. 11). This value is set as the production volume.

  At this time, if the production amount is less than the required amount, the value obtained by subtracting the production amount from the required amount is carried over to the required amount at the previous time. In the case of an extrusion plan, as the production amount, the production possible amount calculated in step S204 is set.

  In the present embodiment, the inventory control method is changed using the non-priority product as a by-product (such as scrap), but the determination may be made using other methods. For example, there is a method of adding a product category field to the item table and changing the inventory control method for an item whose product category is a non-priority product.

  FIG. 20 is an example of the storage / inventory screen 400 in the present embodiment. The entry / exit inventory screen 400 obtains records corresponding to entry / exit / inventory from the start time to the end time from the start time 401, the end time 402, and the entry / exit inventory table (FIG. 18) for displaying the entry / exit and inventory. , A display button 403 that is pressed when displaying in a storage / inventory stock plan display area 404 (described later), and a storage / inventory plan display area 404 for displaying storage / shipping / inventory for each item at a target time. . By using this screen, it is possible to confirm how the warehousing / shipping / inventory transitions as a result of production planning.
