Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
215 words
A production control system for controlling a plurality of producing points (1, 2, 16) so that products are produced while supplying parts among the producing points, said production control system comprising: a first producing point (1) which is used as a center producing point and includes a data base; second producing points (2, 16) respectively having a data base; and one or a plurality of communication networks (3) coupling the data bases of said first producing point and said second producing points, said first producing point (1) comprising: first means for managing at least process sequence information (151) which describes production processes and production times of each products for each of the first and second producing points, capability information (152) which describes the capability of each process for each of the first and second producing points, and surplus item information (153) which describes surplus parts and/or products for each of the first and second producing points; second means for determining an optimum producing point for producing each product out of the first and second producing points based on new order information (150) for each product received at each of the first and second producing points; and third means for instructing production of each product to the optimum producing point based on the new order information.
Claim 2
Dependent Claim
85 words
The production control system as claimed in claim 1, characterized in that said first means further manages stock planning information (154) which describes the number of parts available by time for each part in correspondence with each of the first and second producing points (1; 2, 16), stock master information (155) which is related to supply of each part for each of the first and second producing points, and calendar information (156) which describes working days of each of the first and second producing points.
Claim 3
Dependent Claim
111 words
The production control system as claimed in claim 2, characterized in that the stock planning information (154) includes first stock planning information (154-1) which describes the number of parts available by week for each part in correspondence with the optimum producing point, and second stock planning information (154-2) which describes the number of parts available by week for each part in correspondence with the second producing point (2, 16) which is instructed to supply the parts, and the stock master information (155) describes the second producing point which is to supply each part together with the number of parts and the time period in which the parts are to be supplied.
Claim 4
Dependent Claim
97 words
The production control system as claimed in claim 3, characterized in that said first producing point (1) further comprises: fourth means for determining out of the second producing points (2, 16) an optimum supplying point which is to supply the parts required for the production in the optimum producing point depending on the new order information (150) by investigating the first and second stock planning information (154-1, 154-2); and fifth means for instructing the optimum supplying point to transfer to the optimum producing point the parts which are required for the production in the optimum producing point.
Claim 5
Dependent Claim
68 words
The production control system as claimed in claim 4, characterized in that said second producing points (2, 16) respectively comprise means for notifying to said first producing point (1) via said communication network (3) the new order information (15), the process sequence information (151), the capability information (152), the surplus item information (153), the stock planning information (154), the stock master information (155), and the calendar information (156).
Claim 6
Dependent Claim
55 words
The production control system as claimed in any of claims 1 to 5, characterized in that said first producing point (1) includes a computer aided design system (7), a production management system (8, 23, 24), and an internal local area network (19, 21) which couples the computer aided design system and the production management system.
Claim 7
Dependent Claim
58 words
The production control system as claimed in any of claims 1 to 6, characterized in that said second producing point (2, 16) includes a computer aided design system (10, 38), a production management system (11, 30, 31), and an internal local area network (26, 29, 33) which couples the computer aided design system and the production management system.
Claim 8
Dependent Claim
55 words
The production control system as claimed in any of claims 1 to 7, which further comprises a mail box (14) which is classified by customer who places orders by the new order information (15), said mail box being coupled to the communication network (3) which couples said first and second producing points (1; 2, 16).
