Abstract:

The reliability evaluation for systematic fight mission in real time is an inevitably demand of the future wars. In order to solve the computational problem of the equipment system reliability in real time in the phased mission process, an efficient analytical algorithm based on the k/n (G) redundancy model for reliability evaluation is designed. Through the structural analysis of the equipment system and the mission overview, a binary decision diagram (BDD) model is proposed, which is transformed from the redundant fault tree. As for high computational complexity of the traditional method, a more effective algorithm on the basis of the recursive algorithm is designed. Taking the remote target attack mission of the aviation equipment system for instance, the simulation results indicate that the effective results of the phased mission reliability are obtained by using the proposed method. And the results show that the computational efficiency of the proposed algorithm is significantly improved compared with the traditional algorithm. It is applicable for the computational analysis of reliability of the largescale systematic fight mission in real time and further direct mission plan.
