Research on equipment maintenance decision system based on health management

This paper addresses the importance of equipment health management integrated into the activities of equipment maintenance and management. Firstly, the equipment health management is defined and its main activities are analyzed, including analyzing equipment health factors, processing health data, evaluating and predicting health condition, and solving health problems. Then, a flexible software frame for the equipment health management is constructed with a proper consideration of the requirements of high integration in technologies for complex equipments. A variety of data necessary to support equipment maintenance decision optimization is described, such as fundamental data, condition data, maintenance record data and decision model data. Furthermore, the relationship of important functional modules is depicted. Finally, with the case of equipment maintenance decision system for spaceflight launch site based on the health management activities and the flexible software framework, this paper indicates differences and improvements of the system contrasting with other existing systems.
