Fault management apparatus, fault management method, fault management program and recording medium

Abstract

A fault management apparatus that enables calculation of evaluation values relating to a fault occurring to a management target as objective values without involvement of human judgment is provided. Fault information containing fault content information showing content of a fault occurring to a process in a production line, and detection status information and action content information associated with the fault is stored in a fault occurrence history storage part as a fault occurrence history. A fault extraction part reads the fault occurrence history from the fault occurrence history storage part to extract fault information containing specific fault content information. An influence degree calculation part calculates a degree of influence showing the degree of influence caused by a specific fault by performing statistical processing based on detection status information and action content information contained in the fault information extracted by the fault extraction part.

Description

technical field [0001] The present invention relates to a failure management device, a failure management method, a failure management program, and a recording medium recording the program, which manage reliability analysis and failure cause analysis of managed objects, for example, by the FMEA method. Background technique [0002] Conventionally, FMEA (Failure Mode and Effects Analysis) has been used as a management method for a production line producing specific products. Process FMEA is a process management method to study the countermeasures when failures occur in a specific production line based on the process FMEA table, which is a list that records information such as processes, functions, phenomena, effects, and countermeasures for each predicted failure mode. [0003] In the process FMEA, information on the degree of influence, frequency of occurrence, and degree of detection is set for each failure mode as values ​​for examining whether countermeasures are necessar...

AI Technical Summary

Problems solved by technology

[0008] 5: Have a major impact on the function and performance of the product

[0009] 4: It does not have a major impact on the function and performance of the product, but has a major impact on the productivity and straight line rate in the factory

[0010] 3: Medium impact on in-factory productivity and straight line rate

[0011] 2: A certain degree of influence on the productivity and straight line rate in the factory

[0014] 5: In general, failures do occur, and they occur frequently in subsequent processes

[0015] 4: Frequent failures occurred in the actual performance of similar products

[0016] 3: There is a possibility of failure

[0020] 5: Give it to the user and become a market complaint (claim)

[0025] As above, each evaluation standard is qualitative, and it is easy for the evaluation person to intervene in subjective factors

[0026] On the other hand, for example, it is conceivable that each evaluation value is reviewed (reviewed) by a person different from the person who performed the evaluation to obtain a more accurate evaluation value, but generally the number of processes and failures managed by the process FMEA is large, There is a problem that the time required for review is large
