PHM Collaborative Design in Aircrafts Based on Work Breakdown Structure

Prognostics and health management (PHM) technique has shifted the focus from traditional status monitoring to health assessment, and has become a critical technique in the development of new weapons and in autonomic logistics. However, the design process of the PHM system is not integrated properly in the design of the aircraft, which makes it impossible to achieve an optimal overall design. With this consideration, we introduce the concept of collaborative design into the PHM design. By applying the technique of work breakdown structure, the PHM system and the corresponding aircraft system are decomposed in three aspects: the object aspect, the development aspect and the project aspect. Then the design process of the PHM system and that of the aircraft are integrated based on the breakdown structure in a collaborative way. Then the PHM design in the aircraft can be optimized and the life cycle cost can be reduced.
