基于任务剖面的复杂系统状态综合评估方法

针对复杂系统的多层性、复杂性和系统任务的多样性,提出一种基于任务剖面的复杂系统状态综合评估方法.首先,根据任务剖面建立设备使用清单,依据设备群概念和系统功能构建系统的层次结构和设备群;其次,建立单设备的技术状态评价模型,通过简单而可行的分级综合评估方法得到单设备的技术状态等级;然后,结合各设备的技术状态,采用模糊技术对各设备群进行技术状态评价;最后,根据各设备群的技术状态,结合每个设备群对系统的影响重要度(权重),得到整个复杂系统的综合技术状态等级.通过实例证明该方法简易、可操作性强,具有一定的工程应用价值.

An integrated evaluation method for complex systems condition based on mission sections

On the basis of the multiplayer,complexity and multimissions in the complex system,a kind of integrated evaluation method for complex systems based on mission sections was presented.According to the mission section,the listing of the devices was set up.On the basis of the conception of the device cluster and the system function,the hierarchy of the system and device cluster was constructed.The technical condition evaluation model for single device was established and the technical condition level was obtained by the simple and feasible integrated graded evaluation method.The technical condition of each device cluster was evaluated by combining the technical condition of each device and using fuzzy technology.The hierarchy of the whole complex system technical condition was obtained according to the technical condition of each device cluster and its weighting to the system.The example proved that this method is easy,operable and useful for engineering application.
