Maintenance data management system

For the effective management of manufacturing facilities throughout their life cycle, it is important to collect maintenance data and make use of them for operation and maintenance planning or design of new machines. However, it is seldom that the maintenance data are properly recorded and utilized in a systematic way. To solve these problems, we have proposed a maintenance data management system. In this paper, two major modules of the system are discussed. The first one is a malfunction data collection system which can navigate users to input malfunction cases in a proper format. The second one is a feedback data generation system which induces common causes implied in the malfunction cases by means of the attribute-oriented induction algorithm. An experimental system is applied to malfunction cases of machine tools for demonstrating its effectiveness.
