First, the order received from the customer is first checked against the monthly sales target for each department, and the order data is input through the terminal of the sales department of the first terminal group (MTI-MTl). According to the production request issued by the company, through the terminal of the Product Planning Department, the secondary order confirmation is confirmed by checking the plant's production capacity plan and available raw material inventory. In this way, the order confirmation is made for the production of the order order. For the design, the manufacturing contact table is issued, the quality control team assigns the color number, and the order is completed. .

After the design is completed, the design is sent to the production planning department, the production capacity of each plant is inquired, and the quantity is assigned to each plant based on this design.After the allocation, the production orders are given by the expiration date and the results of the production instruction are given. The computer 10 stores the data in the memory 40. The data on the independent requirements for the item is also stored.

In this way, the material requirements planning function is carried out with the relevant items to create a planned order for items, parts, etc. and adjust the planned order with reference to the exception message, which is better when creating the planned order.

When the adjustment for the planned order is completed, the plan order state is changed from the work order state, and the work order at this time is stored in the memory 40.

The production plan by process and date is established for the work order where the production is confirmed, and the work order is selected by selecting the work order with the work order date. At this time, the order status is changed to a work order order and stocks of necessary components are secured. As a result of the work order, a Token Card, which is a work order for each process, is issued. do.

The work ordered work order is data down from the memory 40 of the primary computer 10 to the memory 50 of the secondary computer 20 for the management of the work site, the memory of the secondary computer 20. In 50, various data collected from the work site (production completion, defect occurrence, etc.) are also stored.

In the work site, the work progress is performed using the work status management function, and various data generated at each site are inputted to the secondary computer 20 through the second terminal group IDT1-IDTn installed at the site and the memory 50 It is included in.

The data recorded in the memory 50 of the secondary computer 20 is dataed up to the memory 40 of the main computer 10 every day. When the report data is reported to the main computer 10, the relationship of inventory changes. It is recorded and maintained as a history in the transaction database.

Each production department reports the final production completion through the third terminal group (FT1-FTm) for the work orders that have been reported at the work site, and various payment data collected daily are collected and the monthly end work is completed. It is linked to the accounting department and used as basic data for costing.

Hereinafter, the contents of the function menu performed by each subsystem of the system of the present invention will be described in more detail by the function menu configuration diagram of FIG.

First, the MPSP menu has functions to determine long-term demand for short-term production resources such as production quantity and short-term production and purchase requirements.It is based on self-planning based on real stock and sales forecast by order order confirmation.

The standard data management menu consists of each sub-menu of the varieties management menu, the routing menu, and the facility data management menu (FDM), of which the varieties management menu manages the standard data of the items and the performance of each item. It consists of the function of managing the data, and the standard data includes the product composition (%) (BOM), defect rate, production lead time, integration standard days, safety inventory, minimum and maximum order quantity, and warehouse for receiving goods ( Location).

In Figure 4, there is a table of products (BOM), which shows the relationship between products and assemblies, assemblies and parts, and parts and components such as parts and raw materials, and maintains all standard data for the varieties. Used to repair.

On the other hand, the process management menu consists of inquiring and maintaining the process database to manage various process standard data required for production, such as the production route and production method of the item, and the facility management menu consists of workshop, machine, production capacity and cost. It is a function that manages standard data for all resources of the company, such as various data about the company.

The design menu obtains all the design data and computerizes various aggregates and analytical data to provide basic data on the computerization of the entire production process. This design work is done directly through the terminal, so standardization and history of the design data is possible. Using the accumulated data, it is possible to simply design a duplicate design of the same content and a similar design. The design menu consists of the sub-menus of the main design menu and the blanket design menu. In particular, the main design menu consists of the product scheme necessary for order-specific design and design publication, design data management, material requirements planning, and It consists of functions such as registration of new items.

Inventory management menu creates and manages inventory data for items, and creates a pure inventory management (1A) menu and standard production plan (MPSP) that receives data on all inventory generated from other systems and classifies them into transaction codes. It consists of submenus of the Material Requirements Planning (MRP) menu, which establishes the inventory management plan for each item to execute the production plan, and creates and manages the planned orders for the production plan execution.

Figure 5b shows the firm planned order number, which is the state of the order ('F' state) which is determined to be put into production for the planned order generated by the material requirements planning. Therefore, when modifying the original plan, if it is already in execution or if the existing plan is changed, the plan for the period that might cause great confusion on the production site will be separated and used. There are two cases in which an order is artificially created for the purpose of correcting it by a state or an accident.

The production execution plan menu consists of three menus: Capacity Requirement Planning (CRP) and Shop Order Load Analyisis and Report (SOLAR).

The capacity planning menu consists of allocating planned orders by plant, determining production lines and air by planned orders, and establishing capacity plans for each workplace.

The production rank planning menu is for supporting work plan establishment and analysis.In order to produce the planned orders made by the inventory management plan in accordance with the ordered process, the workplaces are determined by the work orders in consideration of the production capacity of the factory and the work for each detailed workshop It consists of the function of establishing an order production plan and managing it.

The work order management menu is a function for creating a work order corresponding to this planned order and issuing a work order, i.e., a token card, for a work order when a work order date arrives within a certain period of time for a planned order created by work requirements planning. And the ability to manage production progress based on work orders, report on completion and output, and update inventory.

7 is a flow chart for the work order management function described above.

A work order is divided into a work order created for a firm plan order for work orders and a work order order for which work orders are issued. Work orders are based on the created work order. This is an order that is ready for the component, i.e., an order that does not interfere with the start of production. When this work order is created, the stock of the lower component is stocked and its order is placed in the on-order state. It is inserted into the planned goods receipt as a subitem of the order and calculated as variable stock. Therefore, in managing the work order, if a higher order is designated, it is possible to know the subitems for the configuration of the corresponding product.

Figure 6 shows a sample of the token card, which is a work order issued by the work order management, which contains the indication quantity, production start date and completion date, and the sub-component number of the production order item. Perforations for input and inquiry of the.

The token card issued as described above is transferred to each production site, while the data of the indicated work order order is data down from the memory 40 of the main computer 10 to the memory 50 of the secondary computer 20, and the working status. Used as data for management.

The work status management menu receives the work order data from the main computer 10 from the main computer 10 from the sub computer 20 for efficient management of the production site.
