摘要
多阶段任务系统(PMS)是一种典型的复杂系统,它包括多个在时间上连续且无相互重叠的阶段任务,执行作战与使用任务的武器装备多数属于这种复杂系统。分析了PMS及任务可靠度、可信度和任务效能等任务持续能力评价参数。结合实际装备系统大都属于可用马尔可夫过程进行描述的可修复系统的特点,为简化模型复杂程度提出了一些合理的假设条件。在此基础上,结合多阶段任务系统自身特点,通过分析多阶段任务系统任务持续能力建模仿真步骤,多阶段任务系统任务效能仿真方法,建立了基于Petri网的多阶段任务系统任务效能多层仿真模型。最后结合常见的"靶场打靶"任务进行了实例验证,并对仿真结果进行了分析。
Phased-Mission System (PMS) is a kind of typical complex system. It includes several Phased Missions which are sequential and non-overlapped with each other in mission time. Most weapon system to execute battle mission and usage mission are fallen into this complex system. PMS and its' mission sustainability evaluating parameters including mission reliability; dependability and mission effectiveness were analyzed. In view of the characteristics that fact weapon systems mostly belonged to repairable system which could be described with Markov process, some hypotheses were given for predigesting the complexity of models. Then, by analyzing PMS mission sustainability modeling steps and PMS mission effectiveness simulation method, PMS mission effectiveness multilayer simulating models based on Petri-net were established combining to PMS self-characteristics. Example validation and simulation result analysis were given with mission of target practice.
