PHM-based Dynamic Reconfiguration Technology for DIMA

Prognostic and Health Management (PHM) is generally regarded as the basis for Distributed Integrated Modular Avionics (DIMA). As known, PHM theory plays an important role in the process of resource reorganizing, system reconfiguration, system fault tolerance and task credibility improvements. Hence, this paper firstly presents the fundamentals of PHM technology, and the architecture of DIMA is discussed later. Then, the mission-based reconfiguration mechanism for DIMA is provided and we also give the PHM-based reconfiguration model. Finally, the future applications of PHM technology in avionics are discussed.
