Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, manufacturing a product, procuring parts of the product from a plurality of parts processing companies and assembling these parts to produce products for sale. The present invention relates to a production management device applied to management.

[0002]

2. Description of the Related Art FIG. 7 is a block diagram of a production management apparatus. A product manufacturer 1 that orders parts of a product procures from a plurality of parts processing companies 2 that receive parts, and assembles and sells products from these parts. The product manufacturing company 1 and the component processing company 2 have their own production management devices, and these production management devices are system-independent. The information on the unique product assembly is held in the production management device of the product manufacturing company 1.

A production management device in a product manufacturing company 1 includes a server computer 4 having a database 3 and a production plan input terminal 6 via a company LAN (local area network) 5 and a plurality of production result input terminals 7-1 to 7 through an in-house LAN (local area network) 5. −
n, a purchase management terminal 8 is connected. In such a production management device, for example, all the production plan information of the unique product manufacturing is input from the production plan input terminal 6, and the production result information is also output after the processing of the product, to the production result input terminals 7-1 to 7-n.
The work of inputting from is performed.

On the other hand, the production management device in the component processing company 2 has terminal devices 9-1 to 9-1 for inputting component information.
9-m or server computer (not shown)
They are connected by N10. In such a production management device, the operation of inputting production results such as component processing from each of the terminal devices 9-1 to 9-m is performed independently by the component processing company 2.

[0005] In such a product manufacturing company 1 and a parts processing company 2, when manufacturing a product, the product manufacturing company 1 makes a processing request for the parts to a plurality of parts processing companies 2 in writing or the like. On the part processing company 2 side, an estimate or a delivery date response to the processing request is returned in writing or the like.

[0006]

As described above, the production management apparatus for assembling a unique product exists only in the product manufacturing company 1. In the parts processing company 2, the production management device of the ordering side product manufacturing company 1 does not exist. It is impossible to know the production information such as a specific product held by the product manufacturing company 1 as a whole or individually.

[0007] Further, the production management device in the product manufacturing company 1 inputs all production plan information specific to product production from the production plan input terminal 6, and also outputs the production result information after processing the product. Although the operation of inputting from 7-1 to 7-n is performed, if the part manufacturing is not performed in the product manufacturer 1 or the number of parts processing in the product manufacturer 1 becomes extremely small, The operation of inputting the production result information after processing cannot be performed, and the processing result cannot be referred to in real time through the production management device. The so-called hill-sloping processing for the processing steps and the schedule of the processing steps based on the so-called production plan information does not make sense.

[0008] Even if there is a production management device such as a supply chain management system that connects companies for parts procurement, there is no mechanism for the principle of competition to work directly between suppliers. Production management remains unchanged. Also, if the parts procurement amount fluctuates, the work amount at the conventional supplier also fluctuates. Therefore, the cost setting at the part processing company 2 is based on the expected price set by the parts processing company 2 in advance. In many cases, the market price is merely a reference price, and the price differs for each part processing company 2.

As described above, even if the product manufacturing company 1 that relies on many parts processing outside the company, it is possible to construct a production management device for the delivery date of parts procurement and cost management outside the company. However, it is not possible to judge whether the delivery date and cost of the part processing itself, which is dependent on the outside in the system, is appropriate in the market.

[0010] For this reason, the principle of market competition rarely acts on the delivery time and cost of parts unique to a product except for general distribution parts by mass production, which is a factor that limits the shortened delivery time and cost reduction of product development. . In addition, this appears as a difference in development period and manufacturing cost for each company.

[0011] It is difficult for the parts processing company 2 which is the supplier of the parts to directly know information about what kind of work is requested from which product manufacturing company 1 when the parts are processed. Based on the collected business information, the production quantity is planned by estimating the order quantity and contents by themselves.

However, it is generally difficult to accurately estimate the amount of work that has been ordered until a drawing or a specification arrives from the requestor, and thus an error occurs between the amount of work actually generated and the amount of work predicted in advance. . For this reason, there is a case where waste occurs in waiting for equipment and people, and a situation occurs in which a part manufacturer other than the company is requested to perform an overflow in order to perform an unexpectedly large amount of work. This causes delays in processing and delivery of ordered parts and increases costs.

In the production management device of the product manufacturing company 1 in which most of the parts depend on the external component processing company 2, if all the production plan information is input and all the production result information is not input, the production management device is not used. Cannot refer to the processing result information in real time. For this reason, these performance information is obtained indirectly or directly from the component processing company 2 by obtaining the production performance information, and the product manufacturing company 1 own production performance input terminal 7-
It is necessary to input from 1 to 7-n.

However, in reality, it is impossible to obtain real-time production result information because the network between the product manufacturing company 1 and the parts processing company 2 is not connected. Even if it is available, it is often not possible to use the part processing result information as it is because the same production management device is not used.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a production management apparatus capable of applying the principle of market competition to the delivery date and cost of a product-specific part excluding general distribution parts.

It is another object of the present invention to provide a production management apparatus capable of disclosing in advance an accurate production plan of a product manufacturing company requesting part processing and giving a supplier a preparation period. .

Further, according to the present invention, a production result input terminal or input software of a product manufacturing company requesting a part processing is installed in the part processing company via a network, and the production result information is directly transmitted from the part processing company in real time. It is an object of the present invention to provide a production management device capable of inputting.
