Abstract:Battlefield damage suffered by submarine in the course of combat will have a negative impact on the combat effectiveness of submarine. It is of great significance for submarine to effectively fulfill its mission to properly deal with battlefield damage and quickly restore combat effectiveness. Battle damage rush repair is to complete the rush repair work and resume the operation of equipment in the shortest time. The Bayesian network has the ability to deal with uncertain problems, which can effectively clarify the priority of battle damage rush repair and make up for the time loss caused by the inconsistent decision of submarine battle damage rush repair. In this paper, the system equipment on the submarine is connected according to the interaction relationship, and the submarine equipment Bayesian network model is constructed. By calculating the influence degree of each system equipment damaged on submarine combat situation, the priority of war damage repair of the system equipment is determined. Therefore, the sequence of various emergency actions can be arranged to improve the efficiency of emergency repair.
