针对当前缺乏科学合理的理论和方法确定导弹系统级测试性指标的现状,提出一种面向任务需求的测试性指标确定方法.将导弹任务剖面划分为贮存、出库、部署和发射四个阶段,并提出各个阶段相应的测试需求;分别建立基于贮存可用度、战斗准备任务成功率、部署战备完好率和发射任务成功率为性能要求的测试性需求子模型,给出各个性能指标与测试性参数的关联关系,并选择影响性能较大的测试性参数作为设计参数;提出评价导弹任务性能综合指标,采取修正任务阶段性能要求的方法解决各个任务阶段测试性指标要求不一致的问题,综合得到可信的导弹测试性指标要求.%In view of the lacking of theory and method in determining missile system level testability indices, this research presents a tesability indices detemeining method oriented to mission requirements. The missile mission is divided into four phases, such as storing, combat preparation, disposition and launch. Then the test requirement of each phase was proposed. Based on the pefomance nequirements of store availability, combat preparation mission success rate, disposed combat reatdiness rate and launch mission success rate, some testability requirement models were built. The relationship between the performance requirements and testability parameters were given, and the testability parameters which were the key factors on the performance were selected. It defies an aggregative index to evaluate the missile mission performance, and then modifies the mission phases performance requirements to unify the testability indices which may vary in deferent missions. The credible testability indices are gained synthetically.
