Abstract

Management information is collected from a plurality of production lines that are distributed to a plurality of factories or foundries. Manufacturing schedules of the respective apparatuses constituting each production line are drawn up based on the collected management information and data stored in a database beyond the framework of each factory or foundry so that the entire manufacturing efficiency is increased. Then, production lines (apparatuses) are selected according to the schedules thus determined and product lots are managed and transport arrangements are made so that manufacturing steps of a product are executed by the selected production lines (apparatuses).

Claims

1. A manufacture managing method comprising the steps of:

collecting pieces of management information of a plurality of production lines;

making up manufacturing schedules of respective manufacturing apparatuses constituting each of the production lines based on the collected pieces of management information; and

selecting a most suitable one from the production lines based on the manufacturing schedules.

2. The manufacture managing method according to claim 1, wherein data of transport times and/or transport costs of items between the production lines are managed, and wherein the making-up step refers to the data in making up manufacturing schedules.

3. The manufacture managing method according to claim 1, wherein the management information includes operation states of respective apparatuses constituting the associated production line.

4. The manufacture managing method according to claim 1, wherein the management information includes a yield of the associated production line.

5. The manufacture managing method according to claim 1, wherein the management information includes performance-indicative values of respective apparatuses constituting the associated production line.

6. The manufacture managing method according to claim 1, wherein the management information includes a stock of parts and materials of the associated production line.

7. The manufacture managing method according to claim 1, further comprising the step of receiving a specification from a production requester, wherein the making-up step makes up manufacturing schedules of respective manufacturing apparatuses based on the received specification and the collected management information.

8. The manufacture managing method according to claim 7, wherein the making-up step makes up plural sets of manufacturing schedules, and wherein the manufacture managing method further comprises the step of presenting a plurality of estimates to the production requester based on the plural sets of manufacturing schedules to allow the production requester to make an order by selecting from the estimates.
