Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is suitable for a business entity that carries out high-mix low-volume production, and is capable of promptly delivering to a customer's order and at the same time preventing excessive inventory. The present invention relates to a high-mix low-volume production method that is highly resistant to sudden changes in the market environment, a design / manufacturing integrated production system, and an interface device for design information and manufacturing information.

2. Description of the Related Art Optimization of production processes in mass-produced products such as automobiles and clothing is performed by, for example, optimizing inventory management and parts procurement by an enterprise resource planning system ERP (Enterprise Resource Planning). On the other hand, for a made-to-order product such as a production facility, optimization is performed by standardizing design information by a manufacturing data management system PDM (Product Data Management System).

For example, in the case of an automobile, which is a typical mass-produced product, the break-even point is set at an annual production of 200,000 units per production line. Therefore, one car model produces 20
If we can produce and sell more than 10,000 units, the profit margin will be very favorable. Further, if the annual production of 200,000 units can be secured by combining a plurality of vehicle types, the break-even point can be secured by the mixed flow production in which a plurality of vehicle types are manufactured in one production line. In such mass-produced products, inventory management and optimization of parts procurement are very important sources of competitiveness in corporate operations, and therefore ERP is being actively introduced.

Further, as typical multi-product small-quantity production, there are, for example, petroleum refining plants and plant equipment for power plants.
These plant products have an annual production volume of several to several hundreds, and the types of products are diverse because the products are designed according to the customer's specifications. In extreme cases, there are many cases in which custom-made products are manufactured such that only one unit is manufactured. Even in such a high-mix low-volume production, the introduction of the product configuration management system PDM is effective because many items can be commonly used for each type at the component level.

[0005]

However, in a company that manufactures a wide variety of products in small quantities, not only plant equipment with a long product life as in the past, but also the life cycle of products such as machine tools and semiconductor manufacturing equipment Many have a short product life of several years. When the product life is short, the customer needs to quickly recover the investment cost by shortening the order from machine maintenance to delivery. In this case, like the high growth period in Japan,
When demand is steadily increasing, we were able to reduce the delivery time to the customer and reduce the manufacturing cost by introducing forecast production. However, in today's rapid technological innovation, there is a risk that product obsolescence will progress rapidly, and mere forecast production may cause a large amount of defective inventory of products when demand drops sharply. It was a challenge.

The present invention has been made in view of the above circumstances, and shortens the period until product delivery in the case of high-mix low-volume production in which products are delivered according to customer specifications.
It is an object of the present invention to provide a high-mix low-volume production method, a design / manufacturing integrated production system, and an interface device for design information and manufacturing information, which can prevent defective inventory of prospective production products due to sudden changes in demand.

Have a process.

In the high-mix low-volume production method having such a process, the product to be ordered is divided into a standard unit and a custom-made unit, and a manufacturing control number corresponding to an order code indicating an order is given. By allocating inventory items or making purchase arrangements for standard units, we will achieve production cost reductions due to mass production effects and shorten delivery times by securing inventory items. For custom-ordered units, production is performed according to the order specifications, but since the part in charge of this custom-made unit is limited to the range not included in the standard unit, the custom-made unit is divided into the standard unit and the custom-made unit. By reducing the dwarf, production cost and delivery time can be shortened. When assembling a standard unit and a custom-made unit to manufacture a product, the manufacturing control number is used to associate with the order code.

As shown in FIG. 2, the integrated design / manufacturing type production system of the present invention that achieves the above-mentioned object is a corporate resource plan in which the stock state is managed by using a standard product serial number in response to a standard unit arrangement request. A system (ERP) 400 and a manufacturing data management system (PDM) 200 that stores a standard unit applicable to an ordered product together with a standard product serial number.

In the apparatus configured as described above, the stock state of standard units is managed by the enterprise resource planning system (ERP) 400, so that the production cost can be reduced by the mass production effect and the delivery time can be shortened by securing the inventory. The standard unit applicable to the product ordered by the manufacturing data management system (PDM) 200 is stored together with the standard product serial number, the use of the standard unit is considered first, and then the custom-ordered unit is used. . After the custom-ordered unit is designed for the product to be ordered, the custom-ordered unit management unit 420 manages the production order of the custom-ordered unit by the custom-ordered product serial number. The ordered product assembly management unit 430 manages a state of assembling the ordered product in combination with a standard unit having a predetermined standard product number after manufacturing the custom unit having the custom product number.

Preferably, when the manufacturing data management system is operated so as to increase the standard unit composition ratio of the ordered product, the manufacturing cost of the ordered product and the shortening of the delivery time can be achieved as a whole enterprise. Preferably, in the manufacturing data management system, a standard product serial number is created for each manufacturing unit, and the standard product serial number is supplied to the corporate resource planning system, depending on whether the manufacturing unit is one product manufacturing or lot manufacturing.

12). On the other hand, if you enter the standard product serial number for each supplier (S
114), the custom-made product serial number entered in the product serial number allocation table is reflected (S116). Then, the information of S110 and S
Using the information of 116, the ECN number is sorted by product number (S118). Here, the procedure for distribution differs depending on whether the standard unit is manufactured or purchased. When manufacturing standard units, specify the business operator or factory of the manufacture,
The designated company or factory is informed of the number of standard units to be manufactured and the delivery date. When purchasing a standard unit, the agent or business operator of the purchase destination is specified, and the specified agent or business operator is informed of the number of standard units scheduled to be purchased, the delivery date, and the planned purchase price. Here, the case where the standard unit is manufactured by the factories A and B of the company will be described as an example, and the standard unit manufacturing will be distributed to either the factory A or the factory B by distribution. .

Next, the factory in charge of manufacturing the standard unit is reflected in predetermined items of the ECN number table, the item registration target table, and the BOM registration target table of the ordered product (S120). If the standard unit is composed of sub-units such as the standard parts unit,
The configuration of the subunit is disclosed in the BOM registration target table. Therefore, the standard product allocation of the ECN number for the standard component unit is performed (S122). In this way, the information necessary for manufacturing various standard units is transmitted from the design department to the manufacturing department (S136).

On the other hand, the custom-ordered units of the design change notification ECN issued in S102 are transmitted from the design department to the manufacturing department as they are (S138). The design change notification ECN is also distributed to the production control department in the company (S132). If the standard parts unit can be applied to the custom-made unit, the production control unit specifies the ECN number for the standard parts unit (S134), and S122.
The ECN number is assigned as a standard item.
