도시철도차량 유지보수 정보화 시스템을 위한 사고/고장 분류체계 표준화에 관한 연구

Failure code is that illustrates why an asset failed or the reason that the asset failed. It is generally used in computerized maintenance management systems like failure codes in copier mentioned in the introduction. However, to get the wide usefulness, like being able to express various failure modes or complex failure modes, it should be expanded. Expanded failure code, which includes data of maintenance history, classification of failure and the reason of failure mode, etc, makes it possible that data gathering and standardized maintenance work. As one of the standardization for IT Maintenance System of Urban Transit, it is necessary to classify and standardize failure codes. To get this, we analyzed current failure data and made an expanded standard code system which includes the standardized classification rule of failure and code numbering system. Advantageously, expanded standard code system make that users can take steps of standardized overhaul and inspection as proposal maintain contents when failure occur or something wrong in vehicle of urban transit.
