Mission Reliability Evaluation of Dynamic Distributed Cooperative Systems Based on Multi-agent Modeling and Simulation

Dynamic Distributed Cooperative Systems ( DDCSs ) are complex repairable systems with the characteristics of distribution, dynamism, and cooperation, which makes it difficult to evaluate their mission reliability. Traditional reliability analysis methods either simplify the system or face the problems such as dimensional curses and space explosions. To address this issue, the paper proposed a multi-agent based modeling and simulation method. The method can first construct multiple agents to decompose the "distributed" characteristics of systems, and secondly define the state transfer of agents to describe the "dynamic" characteristics during operation, and then determine the communication rules between agents to simulate the "cooperative " characteristics during mission process and achieve the mission reliability evaluation. At last, an aviation security system of an aircraft carrier is taken as a case study, the feasibility, flexibility, and strong solving ability of the proposed method are demonstrated by evaluating its mission reliability.
