摘　　要：在地面雷达武器威胁环境里,不仅需要评估航路上飞行平台的有关生存和任务完成的概率,而且还要能度量不同航路的好坏;由于传统模型不能有效表达生存模型和任务模型,更不能有效统一生存模型与任务模型,为此建立了基于马尔科夫链的生存任务模型,并且在此模型的基础上引入代价来评估航路;最后的仿真结果表明,该方法有效刻画了生存率和任务完成率,能关注到完成任务且无伤害返回的概率,并且能有效度量航路的好坏。The uncertain about survivability and mission of platform flying in hostile environments consisted of radars and weapons make route planning or other problems difficult to solve, it is not only necessary to assess the probability of survival and mission completion of the flight platform on the flight path, but also to measure the quality of different routes. It is important to unify survivability and mission and evaluate route in the uncertainty hostile environment. It is a trial presented here to describe the survivability--mission model and the evaluation of route based on Markov chain for platform. The probability that platform can achieve missions before getting back with no harm is an important point to measure route. Experimental results show that the method can build not only suvivability--mission model, but also depicts the dependencies between states, and can evaluate route between survivability and mission effectively.
