Description

  The present invention relates to a production planning device, a production planning method, and a production planning program, and in particular, when a product of a different quality is produced as a by-product when a product of a certain quality is produced, the order quantity of each quality is wasted. The present invention relates to a production planning apparatus, a production planning method, and a production planning program for realizing a production plan with a small amount of operations by a simple operation.

  Conventionally, production of products that are on the market in large quantities is expected to be produced and stored as product inventory based on pre-established shipping plans and production plans, and to be delivered with customer inventory allocated to customer orders. Production method was common. However, in the prospective production method, the predicted plan is far from the actual demand, which causes problems such as an increase in the inventory of products that are stored dead or a shortage of product inventory that makes it impossible to respond to orders.

  On the other hand, in recent years, an order production method has been mainly used, mainly for information equipment products, which receives orders from customers, produces specified items in specified quantities, and delivers them to customers on specified delivery dates. It is becoming. Since the order production method produces only what the customer needs, there is an advantage that unnecessary product inventory is eliminated. In such an order production system, it is important to produce with a production schedule in time for a delivery date specified by a customer.

  Conventionally, many techniques have already been disclosed for production scheduling. For example, in Patent Document 1, a display method for easily grasping the relationship between a load and an order when scheduling is performed by assigning a load by day based on the required number of days for each order and adjusting the load using the result. A production scheduling apparatus that realizes the above is disclosed.

  However, depending on the type of product, some products are produced with a certain level of quality. For example, in a production line for light emitting diodes, the brightness indicating brightness per predetermined area and the color of the diodes are not exactly the same. For this reason, there are cases where brightness and color that fall within a certain range of quality and those that fall within a different range are treated as different products. The ratio of the production of products of desired quality to the production of products excluding defective products is called yield.

For example, Patent Document 2 and Patent Document 3 disclose a method for rescheduling work delays due to the occurrence of defective products.
Japanese Patent Laid-Open No. 6-19924 JP 2004-118472 A JP 2000-067111

  However, the techniques described in Patent Documents 1 to 3 are techniques for readjusting the schedule, and are simple algorithms in which defective products are treated as defective products.

  As described above, in a product such as a light emitting diode, a product that falls within a certain range of brightness and color and a product that fits in a different range are treated as different products. That is, it is not simply handled as a defective product, but can be managed as if another product was produced. Specifically, when 500 orders for product A are placed and 500 products A are made with the aim of product A, 400 products A and 100 products B are considered. In this case, since the yield of the product A is 80%, it is sufficient to produce 625 pieces. As a by-product, 125 products B are produced.

  In addition, for example, in the case of a light-emitting diode, a product that can be produced as a by-product is different only in quality such as luminance, so that it may be handled as the same product depending on the customer.

  A first object of the present invention is to provide a mechanism for efficiently producing a production plan by a simple operation for each product when another product is produced as a by-product during the production of the product. It is.

  The production amount adjustment input device 103 is generally installed in the production management department, and the customer order data input from the sales distribution system order registration device 102 and the sales input from the sales prediction data input device 101 are used. A process for obtaining the shortage from the forecast data and passing it as production plan data (order data for the manufacturing department) to the order production inventory balance adjusting device 104 is executed.

  The made-to-order production inventory balance adjustment device 104 performs a balance adjustment process in consideration of a by-product described later, creates a replenishment plan, and executes a process of delivering the replenishment plan to the production amount adjustment input device.

  The production planning device 105 of the present invention is a system including the production amount adjustment input device 103 and the made-to-order production inventory balance adjustment device 104 shown in FIG.

  FIG. 2 is a hardware configuration diagram illustrating a detailed configuration of an information processing apparatus (computer) that realizes the production planning apparatus 105 according to the present embodiment. Here, the hardware configuration diagram shown in FIG. 2 is the same for all of the sales forecast data input device 101, the sales distribution system order registration device 102, the production amount adjustment input device 103, and the order production inventory balance adjustment device 104. , I will explain collectively.

  In FIG. 2, the CPU 201 comprehensively controls each device connected to the system bus 212. The RAM 202 functions as a main memory, work area, temporary save area, and the like for the CPU 201. Further, the ROM 203 stores a boot program.

  The input control unit 204 controls input from the input unit 205 realized by a pointing device such as a keyboard or a mouse. The display control unit 206 controls display by the display unit 207 realized by a CRT monitor, a liquid crystal monitor, or the like.

Examples of the external memory 209 include a hard disk (HD), a flexible disk (FD), a compact flash (registered trademark) that can be connected to a PCMCIA card slot via an adapter, smart media, and the like. In the present embodiment, it is assumed that the program recorded in the external memory 209 is executed by being loaded into the RAM 202 as necessary.

  In addition, the communication I / F control unit 210 executes communication control processing with an external device via a network 211 such as a LAN or the Internet.

  FIG. 3 is an example of an item data table stored in the external memory 209 of the production planning device 105.

The item data table shown in FIG. 3 shows items of item code, item name, and rank. The item code indicates a code for identifying the product. The product name indicates the name of the product. The rank indicates the quality rank when the product is produced. As will be described later, depending on the customer of the shipping destination, even if the quality rank is different, it can be delivered as the same product, and because the quality rank is specified depending on the customer, only the products of the specified quality rank can be delivered. It has become.

  FIG. 4 is a flowchart showing a control procedure executed in the production planning apparatus 105 of the present invention. The control procedure shown in this flowchart will be described on the assumption that the production planning program stored in the external memory 209 of the production planning apparatus 105 is read into the RAM 202 and started and executed by the CPU 201. However, it is possible not only as a software program but also to construct and implement firmware that implements the functions shown in this control flowchart.

  In step S401, a data capture screen (FIG. 5) for instructing capture of PSI data is displayed on the display unit 207. PSI means production, shipment / sales (Sales), and inventory.

The production planning apparatus 105 of the present invention takes in customer order data created by the sales distribution system order registration apparatus 102, reads sales forecast data from the sales forecast data input apparatus 101, and reads the read data into production plan data (order data). ) In the external memory 209. This order data is accumulated, and the number of shipments (scheduled shipments), the number of productions (scheduled productions), and the number of stocks (scheduled stocks) for each date are obtained, and PSI data is generated. It is assumed that the PSI data (not shown) has the planned number of orders, the number of planned productions, and the number of planned stocks for each date for each product code and quality rank, and is stored in the external memory 209. When the order data is imported for the first time, only the planned number of future shipments is obtained, and then the production plan is input by the operator (production planner), so that the planned production quantity and the planned inventory quantity are changed by date. To be confirmed.

  FIG. 5 is a screen for fetching sales forecast data and customer order data from a CSV file.

  When the file path of sales forecast data and customer order data is specified in the lower area of the screen shown in FIG. 5 and the CSV data import button is pressed by the operator, the file path specified by the production planning device 105 is specified. The sales forecast data or customer order data stored in is stored in the external memory 209.

  In step S402, PSI data obtained based on the sales forecast data and customer order data captured on the data capture screen is retrieved from the PSI data group stored in the external memory 209, and the retrieved PSI data is read. In step S403, the production planning apparatus 105 calculates and displays the PSI balance management screen shown in FIG.

  FIG. 8 is an example of a PSI balance management screen displayed on the display unit 207 of the production planning apparatus 105.

  As shown in FIG. 8, on the PSI balance management screen, the planned shipment quantity, production schedule quantity, and inventory schedule quantity for each date are calculated and displayed for each product code and quality rank.

  In the example of FIG. 8, it is indicated that the product with the product code “AAA001” having the quality rank “A-01” has an inventory shortage due to the order delivery on September 4th. Since the planned shipment number is a value determined based on the order data for each customer, the “scheduled shipment number” field is described as “order receipt” in the screen of FIG. Hereinafter, “order received” is described in the screen examples, but it is synonymous with the planned shipment quantity.

  The production planning device 105 can accept an operation by an operator via the PSI balance management screen, and can input replenishment plan data on this screen. For example, it can be instructed to produce 30 products of quality rank “A-01” with product code “AAA001” on September 3rd. In step S404, it is determined whether the replenishment plan data is input, that is, whether a numerical value is input to the production column via the PSI balance management screen and the update button is pressed. When the replenishment plan data is input, PSI data is recalculated in step S405, and the numerical values are changed as shown in FIG.

  The first feature of the present invention is that it is produced as a by-product when producing a product of the quality rank as well as a product of the quality rank instructed to be produced by the operator by inputting replenishment plan data. The production plan is also calculated and corrected for products of different quality ranks.

  FIG. 6 is an example of a production rank table.

  The production rank table in FIG. 6 includes items of item code, target rank, reference production number, generation rank, and generation number. The target rank indicates the quality rank of an item that is expected to be generated at the time of production instruction. The reference production number indicates a provisional number at the time of production. The generation rank indicates the quality rank of the item that is expected to be generated. The number of generations indicates the number actually generated when the number of items for the standard production number is produced.

  In the example of FIG. 6, when 1000 items with the item code “AAA001” are produced with the target rank “A-01”, 600 items with the quality rank “A-01” are generated, and the quality rank “A−” is generated. It shows that 400 items of “10” are generated.

  In the example of FIG. 6, the number of generations for each quality rank is given to the table with respect to the standard production number, but it is not limited to this, and the ratio generated for each quality rank is associated as a value. You may leave it on the table.

  The production planning device 105 sets a product rank for which production is instructed by the operator as a target rank, and refers to this production rank table to calculate products of quality rank (production rank) that are produced together. For example, in the example of FIG. 9, since the operator has designated 30 productions with the quality rank “A-01”, “30 × 400/600” is calculated from the production rank table of FIG. It is specified that 20 pieces of “10” are produced. In this way, when the operator gives a production instruction, a production plan is also calculated for the by-product.

  The second feature of the present invention enables delivery without receiving a new production instruction by diverting a product of another quality rank that can be diverted to an order for a product of a certain quality rank. That is.

  FIG. 7 is an example of a diversion table.

  The diversion table of FIG. 7 has items of item code, representative rank, diversion rank, and shipping destination. The representative rank indicates the quality rank of the diversion destination. The diversion rank indicates the quality rank of the diversion source. The shipping destination is information indicating a customer of a shipping destination that can ship a product with a diversion rank as a product with a representative rank.

  In the example of FIG. 7, when the product of the representative rank “B-01” is delivered to the “shipping destination B”, the product of the conversion rank “B-10” is used as the product of “B-01”. Indicates that delivery is permitted. Since these pieces of information are associated with each shipping destination, in the example of FIG. 7, if all the records stored in the diversion table in FIG. This indicates that diversion is not permitted for shipping destinations other than “B”.

  FIG. 10 shows an example of the PSI balance management screen.

  In FIG. 10, it is shown that 50 pieces of orders are received on September 4 and the stock is insufficient for the product with the quality rank “B-01” of the product code “BBB001”. Here, by clicking on the order received column on September 4 with the mouse, as shown in FIG. 11, the detailed information on the received order can be viewed.

  FIG. 11 is an example of a dialog screen showing the detailed information on the order. The delivery quantity is shown for each shipping destination as the details of the item, delivery date, and quantity, and can be diverted to the customer at the shipping destination. Information indicating whether there is a product with a high quality rank is displayed.

  As shown in the diversion table in FIG. 7, “possible” is displayed in the diversion available column when it is stored that a product of another quality rank can be diverted by the customer at the shipping destination. . In the present embodiment, it is shown that there is a product of a quality rank that can be diverted to the shipping destination B. Here, when the reusable shipping destination B field is designated with the mouse by the operator, the PSI balance adjustment screen shown in FIG. 12 is displayed. This process corresponds to step S406 in FIG.

  In step S406 of FIG. 4, the production planning apparatus 105 determines whether or not the operator has designated a diversion instruction, that is, a shipping destination column that can be diverted with the mouse, from the detailed information of the order. If it is determined that the diversion has been instructed, the process proceeds to step S407, and the PSI balance adjustment screen (FIG. 12) is displayed.

  FIG. 12 shows an example of the PSI balance adjustment screen.

  This screen is displayed when the shipping destination to which the product can be diverted is selected by the operation of the operator in the dialog screen showing the detailed information of the order shown in FIG. 11, and the quality of the diverting destination for the shipping destination. The representative rank that is the rank and the diversion rank that is the quality rank of the diversion source are shown. Each quality rank is extracted from the divertable table shown in FIG.

  In this PSI balance adjustment screen, by selecting the diversion rank, which is the quality rank of the diversion source to be diverted, with respect to the representative rank, which is the diversion destination quality rank, and inputting the number of diversions by the operation by the operator The production planning apparatus 105 recalculates the PSI. This recalculation process can be calculated by subtracting the number input to the diversion rank from the representative rank. Here, the number of diverted manually may be input by the operator, but the production planning device 105 may automatically allocate the number of representative ranks that are insufficient to the diverted rank. However, in this case, it is a condition that the diversion rank stock is equal to or more than the distribution. When the diversion rank inventory is not greater than or equal to the allocation, the production planning device 105 may allocate the diversion rank inventory and display the remaining shortage of the representative rank. This is because the operator can instruct additional production on the PSI balance management screen.

  As described above, after displaying the PSI balance adjustment screen in step S407, in step S408, the production planning apparatus 105 recalculates PSI data accompanying the diversion of the item automatically or according to the input of the diversion number by the operator. The PSI balance management screen (FIG. 13) is displayed.

  In step S409, the production planning apparatus 105 determines whether or not the OK button has been pressed on the PSI balance management screen of FIG. 13, and if pressed, stores the PSI data in the external memory 209 in step S410 and ends the process. If the OK button is not pressed and a numerical value is input or an update button is pressed, the process returns to step S404 to repeat the PSI calculation process.

  As described above, according to this embodiment, when another product is produced as a by-product during the production of a certain product, it is possible to efficiently produce a production plan for each product with a simple operation. It becomes.

  Further, according to the present embodiment, when another product is produced as a by-product during the production of a certain product, the product can be diverted when each product can be diverted by the customer of the delivery destination. .
