摘要
针对装备结构复杂、系统对备件修复能力有限、系统子任务层次多、复杂任务系统成功性建模难的问题,首先对任务系统下的各层级任务进行定义,根据各层级任务间的逻辑关系,以任务可用度为保障指标,基于METRIC理论建立了不完全修复系统任务成功性模型;然后,分析了优化后的备件方案下系统任务可用度在不同阶段任务的变化,其走势与实际情况基本相符;最后,通过离散事件建模与蒙特卡洛仿真相结合的方法对模型进行了验证,仿真结果与解析结果基本一致。
It is difficult to build the multi-stage mission system modeling due to the complex structure of equipment,limited system repair capability and system-level multi subtasks.The problem can be dealt with as follows：Firstly,tasks at each level of the system are defined,and based on METRIC,the mission availability is regarded as index to build mission success model of incomplete repair system.Secondly,mission availability changes in different stages are analyzed by examples and the trend of curve is consistent with the actual situation.Finally,the result is testified by combining the discrete event modeling with Monte Carlo simulation method.The simulation results are in agreement with the analytical results.
