[1. overview]
For example, in the production of castings, when material is added (casting), the actual weight +α is added. In the post-process (machining, polishing), offcuts are generated, but they are melted again and re-inserted.

Conventionally, the above-mentioned +α material was also managed as the material cost for the current month. For this reason, depending on the product, there was a large divergence between the input weight and the finished weight, and it was not possible to capture an accurate cost.

Therefore, in the present embodiment, when the material is put in, it is subtracted as inventory, but by taking into account the inventory scheduled to be returned as inventory assets, it is possible to calculate the material balance and used material cost with high accuracy. By improving the accuracy of costs, it has become possible to grasp the cost with high precision.

FIG. 1 is a diagram showing a processing image of this embodiment. As an example, the case of manufacturing copper castings will be described. In FIG. 1, the initial charge is 1,000 kg of copper. Machining yields 900 Kg of copper, and polishing yields 850 Kg of copper. Here, the in-process weight is calculated as follows: In-process weight = inventory weight at the corresponding production number - drawing weight. In this example,
Input weight (1000 Kg) - drawing weight (850 Kg: design weight) = 150 Kg.

This in-process weight of 150 kg is actually put in, but since it will be returned in the future (because it can be reused), it is returned to the material inventory balance. The actual inventory data is "-1,000 Kg", but as an asset inventory, the weight of the work in process is recorded as an inventory to improve the accuracy of the material usage.

In the following description, the manufacture of castings is taken as an example. The present invention is not limited to the manufacture of castings, but can be widely applied to products in which offcuts of materials generated in the manufacturing process can be reused.

In addition, the material calculation unit 102d calculates the cost, and calculates the amount of materials used in the current month based on the weight of the in-process material by the following formula: Amount of material used in the current month = previous month's non-inventory + previous month's in-process weight + current month's inventory - current month's non-inventory - current month's in-process weight calculate.

A specific example of the processing of manufacturing control apparatus 100 according to the present embodiment will be described with reference to FIGS. 4 to 9. FIG. 4 to 9 are diagrams showing sample data for explaining a specific example of processing of manufacturing control apparatus 100 according to the present embodiment.

(1) At the time of inputting an order FIG. 4 is a diagram showing sample data for explaining the processing at the time of inputting an order. In order input processing S1, order data, design data, and manufacturing control data are input and registered in order file 106a, design file 106b, and production number control file 106c. In this way, when the order is entered, the design weight (drawing weight) is registered and the production number is assigned.

In the example of order data, the first line contains order number "J0001", line "1", supplier "Supplier A", item "Casting", quantity "1", order amount "¥10,000", production The number is "S0011". The second line is order number "J0002", line "1", supplier "Supplier B", item "Casting", quantity "1", order amount "¥20,000", production number "S0012". ing.

In the design data example, the first line is order number "J0001", line "1", drawing weight "1,000 kg", the second line is order number "J0002", line "1", drawing weight "1". , 800 Kg”.

In the example of manufacturing number management data, the first line is the manufacturing number "S0011", the item "casting", the quantity "1", the manufacturing number status "work in progress", and the second line is the manufacturing number "S0012", the item "casting ”, quantity “1”, production number status “work in progress”.

(2) At the time of delivery FIG. 5 is a diagram showing sample data for explaining the processing at the time of delivery. In the transfer input process S2, the inventory transfer (delivery) data and the product number weight management data are registered in the inventory transfer file 106d and the product number weight management file 106e, respectively. That is, the material delivery is registered for the product number, and the delivery is performed by drawing weight +α.

In the example of inventory movement (shipment) data, the first line contains the movement number "I0001", line "1", movement date "2020/2/10", item "material", production number "S0011", shipment quantity " 1,500 kg". The drawing weight of the product number "S0011" in the design data is "1,000 kg", but the shipping quantity is "1,500 kg". Therefore, the current inventory will be reduced by 1,500 kg.

The second line has the transfer number "I0002", the line "1", the transfer date "2020/2/25", the item "material", the production number "S0012", and the shipping quantity "2,000 kg". The drawing weight of the product number "S0012" in the design data is "1,800 kg", but the shipping quantity is "2,000 kg". Therefore, the current inventory will be reduced by 2,000 kg.

In the example of weight management data by product number, the first line is the accounting month "2020/2", the product number "S0011", the item "Casting A", the drawing weight "1,000 Kg", and the shipping weight "1,500 Kg". It has become. The second line has the accounting month "2020/2", the manufacturing number "S0012", the item "Casting B", the drawing weight "1,800 Kg", and the delivery weight "2,000 Kg".

At the time of warehousing, inventory movement (warehousing) data is registered in the inventory movement file 106d.

(3) End-of-Month Stocktaking FIG. 6 is a diagram showing sample data for explaining the end-of-month stocktaking process. In the inventory input processing S3, the inventory weight and the in-process weight of the production number weight management data at the end of the month are registered. The in-process weight is calculated by grasping the current weight of the stock at the time of the stocktaking, and then calculating it as "drawing weight-inventory weight".

In the example of weight management data by production number shown in FIG. 6, the inventory weight "1,300 Kg" and the in-process weight "300 Kg" are registered in the first row. In the second line, the inventory weight "2,300 Kg" and the in-process weight "200 Kg" are registered.

(4) Calculation of material usage amount at the end of the month FIG. 7 is a diagram showing sample data for explaining calculation of the material usage amount at the end of the month. In the material calculation process S4, based on the weight management data by manufacturing number, inventory movement (shipping) data, and inventory movement (warehousing) data, the material received in the current month, the outbound material in the current month, and the in-process weight in the current month are aggregated to calculate the material. Ledger calculations are performed to register inventory data in the inventory file 106f. In the material calculation process S4, the cost is calculated, and the amount of materials used in the current month is calculated based on the weight in the work in progress. Calculate the weight.

In FIG. 7, weight management data by product number is held monthly, and incomplete product numbers are carried over to the next month. Since the production number "S0010" is the completed production number, the in-process weight is not required. The in-process status is obtained from the manufacturing number management data using the manufacturing number as a key.

For the difference in inventory weight from the previous month, register a receipt slip separately. The production number "S0009" is 3,150 kg at the end of the previous month - 3,100 kg at the end of the current month = 50 kg. The production number "S0010" is 4,200Kg at the end of the previous month - 4,100Kg at the end of the current month = 100Kg.

In the example of inventory movement (warehousing) data, the first line contains the movement number "I0001", line "1", movement date "2020/2/10", item "material", production number "S0009", and stock quantity " 50Kg", the second line is the transfer number "I0002", the line "1", the transfer date "2020/2/15", the item "material", the manufacturing number "S0010", the quantity received "100Kg", the third line . The quantity received is the returned material generated in the machining and polishing processes.

Inventory data for the current month is calculated from a goods receipt slip (movement input (warehousing) data). In addition, the delivery for the current month is calculated from the delivery slip (movement input (delivery) data). In the example of inventory data shown in FIG. 7, for the fiscal month "2020/2", the item "material", the inventory at the end of the previous month "6,000 kg", the inventory in the current month "350 Kg", the delivery in the current month "3,500 Kg", the inventory at the end of the current month The inventory is "2,750 Kg", the weight in work in progress is "600 Kg", and the inventory at the end of the current month (including work in progress) is "3,450 Kg". The in-process weight of "600 kg" is calculated using the product numbers S0009, S0011, and S0012. Since S0010 has already been completed, it is not included in the in-process weight.

FIG. 8 is a diagram showing a sample material ledger. FIG. 9 is a diagram for explaining cost accounting (cost of materials used in the current month). Referring to FIG. 9, the method of calculating the sample material cost for the current month in the conventional method and the present embodiment will be compared and explained.

Conventionally, it was calculated as follows: "6,000" unstocked in the previous month + "350" in inventory in the current month - "2850" unstocked in the current month = "3,500" used materials in the current month.

On the other hand, in the present embodiment, uninventory in the previous month "6,000" + weight in the work-in-process in the previous month "350" + receipt in the current month "350" - uninventory in the current month "2850" - weight in the work-in-process in the current month "600" = current month It is calculated with the material used "3,250".

In this way, the cost of materials used changes by the amount of the difference (250 kg) in the in-process weight. For example, if the Kg unit price is ¥600, there is a difference of “600×250=¥150,000”. When the in-process weight is reduced, the opposite result (used material cost) is reduced, but the accuracy of the cost incurred in the current month is improved by taking into account the scheduled warehousing that will occur in the future. In a month in which only casting occurs, the input amount will increase (actual inventory decrease), but the weight in the work in process will increase and will remain as an asset as an inventory material, so it will be recorded for each production number. Material costs are apportioned on a drawing weight basis.

As described above, according to the present embodiment, the shipping weight of materials in inventory is registered in the storage unit at the time of manufacturing for each production number, and the weight of remnants in inventory generated in manufacturing is registered in the storage unit. and an inventory input unit 102b that registers in the storage unit 106 the inventory weight of inventory at the end of the month and the in-process weight calculated by drawing weight-inventory weight for each manufacturing number. 102c, and a material calculation unit 102d that aggregates the outgoing weight, the incoming weight, and the in-process weight registered in the storage unit 106 at the end of the month, and calculates the materials used for the current month based on the aggregated in-process weight. Since it is provided, it is possible to calculate the material to be used with high accuracy in the case of manufacturing a product from the material and in the case where the offcuts generated in the manufacturing process can be reused.
