Abstract

A fault processing system processes a fault which is generated in one or a plurality of producing points which design and produce products according to orders received from customers. The fault processing system includes a first producing point which is used as a center producing point, second producing points, and one or a plurality of communication networks coupling the first and second producing points. Each of the second producing points comprise a first device for detecting a fault generated in a program module of the second producing point and a second device for notifying the fault and information identifying program module in which the fault is generated to the first producing point responsive to the first device. The first producing point comprises a third device for analyzing the fault notified from the second producing point depending on whether the program module in which the fault is generated is a common program module or a particular program module based on the information. The common program module is used in common at a plurality of second producing points, and the particular program module is used exclusively in the second producing point to which the particular program module belongs.

Claims

1. A fault processing system for processing a fault which is generated in at least one of a plurality of producing points which design and produce products according to orders received from customers, said fault processing system comprising:

a first producing point which is used as a center producing point;

second producing points; and

at least one communication network coupling said first and second producing points,

each producing point including transmission and reception means respectively connected to said communication network;

each of said second producing points comprising;

first means for detecting a fault generated in a program module of a second producing point, and

second means, coupled to said communication network, via respective transmission means, for notifying the fault and information identifying program module in which the fault is generated to said first producing point responsive to said first means;

said first producing point comprising;

a third means, coupled to said communication network, via respective transmission means, for analyzing the fault notified from said second producing point depending on whether the program module in which the fault is generated is a common program module or a particular program module based on said information, said common program module being used in common at a plurality of second producing points, said part-icular program module being used exclusively in the second producing point to which the particular program belongs,

said third means of said first producing point including a fault diagnosis table storing with respect to each program module an operating point code specifying a producing point where the program module is operating, so that the fault is notified to the producing points having the common program module, based on said diagnosis table.

2. The fault processing system as claimed in claim 1, wherein said common program module is associated in a respective producing point with a structure selected from a group consisting of a production management structure, a manufacturing management structure and a marketing management structure.

3. The fault processing system as claimed in claim 1, wherein said particular program module is associated in a respective producing point with a structure selected from a group consisting of a marketing management structure, an accounting system and a purchasing system.

4. The fault processing system as claimed in claim 1, wherein each program module includes a fault supervision program and said first means of each of said second producing points includes means for notifying the generation of the fault in the program module to the fault supervision program of the program module, said fault supervision program notifying the generation of the fault to said second means.

5. The failure processing system as claimed in claim 1, wherein said third means further includes a general fault diagnosis structure, said diagnosis table further storing with respect to each program module a program module name, a summary of the program module, and a program module classification, said module classification specifying whether the program module is a common program module or a particular program module, said general fault diagnosis structure sorting the faults received from the producing points, depending on said information, into faults which must be dealt with in common for a plurality of producing points and faults which must be dealt with individually for each producing point by referring to said fault diagnosis table.

6. The fault processing system as claimed in claim 1, wherein said first producing point further comprises fourth means, coupled to said third means, for devising a countermeasure for the fault depending on whether the fault is generated in a common program module or a particular program module.

7. The fault processing system as claimed in claim 6, wherein said fourth means further includes means for independently notifying the countermeasure for the fault which is generated in the common program module to the center producing point and means for independently notifying the countermeasure for the fault which is generated in the particular program module to the second producing point which uses this particular program.

8. The fault processing system as claimed in claim 1, wherein said first producing point further includes a first video conference system and at least one of said second product points further includes a second video conference system, so that a video conference between the first and second video conference systems is possible via the communication network.
