摘　　要：指挥信息系统运行环境复杂,易遭受摧毁,这使系统的自主恢复、不间断地保持任务运行变的非常重要。采用有向无环图将信息系统任务分解为应用程序对象集,利用无向图建立系统构件模型,计算得到每个候选节点至失效节点最短自愈时间,定义均衡自愈时间与可靠性的综合函数。仿真结果表明,承载任务的系统构件失效时,提出的面向任务自愈的系统资源优化选择策略能得到最优替换构件,有效地保证任务的持续运行。The working environment of command and information system is complex and easily attacked,which makes the selfrecovery and continuity of mission running very important.The mission was decomposed to application object set using DAG.The system component model was built,and the shortest self-healing time was computed between candidate nodes and failed node.The synthesis function was defined to balance self-healing time and reliability.Simulation results show utilizing system resource optimizing selection strategy proposed can obtain the best component,and keep mission continually running.
