He decided on the number and made a daily production plan. When a new order is scheduled for the product, the current planned number is added to the previously scheduled number of orders (excluding those that have already been ordered and shipped), and the planned number of orders after addition and the actual number of orders are added. The production plan was revised based on inventory numbers.

の在庫が著しく増加する不具合を招いていた。[Problem to be Solved by the Invention] Conventionally, production plans are determined based on the number of orders scheduled for the product and the actual inventory, and the number of products currently assembled on the product production line. The so-called process inventory was not taken into consideration at all. For this reason, when revising the production plan due to the occurrence of new orders, if part of the product production line is stalled due to an accident or the like and product manufacturing is delayed, the actual inventory will be lower than if there had been no delay. Because there were so few products, the number of products to be manufactured in the future was decided to be higher than originally intended, which later led to a problem in which the inventory in the warehouse increased significantly.

When the planned number of orders is input, the input value is stored in the planned number of orders storage section. When the number of products is input, the input value is subtracted from the stored value in the planned order quantity storage section, and the input value is added to the stored value in the inventory quantity storage section. When the number of items to be shipped is input, the input value is subtracted from the value stored in the inventory storage unit.

。[0007] Therefore, the stored value in the planned order quantity storage section is the current planned quantity of orders that have not yet been placed on the product production line. On the other hand, the value stored in the inventory storage unit is the total number of products currently assembled on the product production line, ie, process inventory, and the number of products stored in the warehouse, aka actual inventory. Then, when the value stored in the stock quantity storage section increases due to the input of the number of products and exceeds the maximum value of the preset appropriate stock quantity range, the stored value in the planned order quantity storage section decreases. As a result, when an increase in inventory is expected, the production plan is set to be smaller than the actual amount.

As a result, when the total number of process inventories and actual inventories decreases, the shortage of products due to a smaller production plan can be compensated for. Therefore, the stock in the warehouse is always stabilized, and defects that increase significantly are prevented.

を判別し、該当するプログラム処理を実行する。In the RAM 2, as shown in FIG. 2, there is a planned order quantity table (planned order quantity storage unit) 21 that sequentially stores the planned order quantity of one product by block number, and as shown in FIG. Minimum value (MIN), maximum value (MAX
) and average value (AVE) are set in advance, as well as an appropriate inventory quantity setting memory 22, a product quantity memory 23 for storing the number of products entered by key, an outgoing quantity memory 24 for storing the outgoing quantity, and an inventory. Various memory areas such as an inventory number memory (inventory number storage unit) 25 for storing numbers are formed. Each time the processor 1 receives key input data from the keyboard 3, it determines the input key as shown in FIG. 4 and executes the corresponding program processing.

）Even when the product number key 34 is input, it is determined whether or not numeric data has been input, as shown in FIG. 6, and the following processing is executed only if there is input. That is, the number data is stored in the product number memory 23 as the number of products manufactured from the parts input to the product production line. Next, from the stored values in the planned order quantity table 21, the product quantity memory 2 is
Subtract the number of products in 3. Specifically, first, we compare the planned order quantity of block number No. 1 with the number of products, and if [planned order quantity ≦ the number of products], we set the planned order quantity of block number No. 1 to "0" and change the block number from the number of products. Subtract the expected number of orders for No. 1. Next, the number of products after subtracting the planned order quantity for block number No. 1 and block number No. 2
Let's move on to a comparison with the expected number of orders. In this way, the number of planned orders and the number of products are compared in descending order of the block number, and if [planned number of orders > number of products], the number of products is subtracted from the number of planned orders of the corresponding block number, and the remaining amount is used to receive the orders of the corresponding block number. Replace with the planned number and complete the subtraction process. (Expected Order Number Subtraction Means) Next, the number of products in the product number memory 23 is added to the stored value in the inventory number memory 25. (Inventory addition means)

Note that the method of subtraction in this case is the same as the case of subtracting the number of products from the stored value of the table 21 for the number of expected orders described above. However, if the expected order quantity is negative,
That is, if (inventory quantity - AVE) exceeds the planned order quantity, all the planned order quantities for each block number become "0" and this process ends. (Adjustment means at the time of input)

る。Thus, according to this embodiment, the number of stocks for one product is the total number of actual stocks in the warehouse and the number of process stocks on the product production line, and this stock number is the preset appropriate stock number. When the maximum value of the range is exceeded, an automatic adjustment is made to decrease the registered planned order quantity, and when it falls below the minimum value of the appropriate stock quantity range, an automatic adjustment is made to increase the registered planned order quantity. ing. Therefore, by making future production plans based on the expected number of orders displayed on the expected number of orders display section 4, the manager can reduce the number of parts put into the product production line when the number of inventory is expected to increase. This prevents the stock in the warehouse from increasing significantly. Furthermore, when the number of products in stock decreases due to shipment, the number of planned orders is automatically added, so that the shortage of products caused by setting a smaller production plan can be fully compensated for. As a result, inventory in the warehouse is always stable and efficient production planning can be made. Furthermore, the number of parts to be introduced into the product production line can be determined in accordance with the expected number of orders displayed on the expected number of orders display section 4, which reduces the burden on the administrator.
