Mission-oriented Prioritization Method for Health Management Objects of Complex Equipment

Abstract

Under the conditions of systematic warfare, the diversified mission scenarios and the structure of complex equipment have led to problems such as difficulties in clarifying equipment health management objects and in implementing the allocation of support resources. To solve those problems under the influence of different mission profiles, this paper proposes a mission-oriented prioritization method for health management objects of complex equipment. Firstly, using the graph theory, function-dependent network models are constructed according to the composition of equipment system and mission sessions under the mission profile; Secondly, the PageRank algorithm is used to measure the importance of each system; Finally, combined with the characteristics of the mission profile, the priority list is derived by updating the PR values with expert knowledge, by which the key health management objects are determined. The proposed method is verified with a case study on the design of an equipment health management system. The results show that the method can obtain the priority of each sub-system of equipment efficiently, so as to provide appropriate objects for equipment health management and the distribution of support resources.
