系统故障演化过程的可拓学原理

An Extension Theory of System Fault Evolution Process

为研究系统故障演化过程(System Fault Evolution Process,SFEP)的表示、分析和处理,利用智能理论并满足对系统功能状态的分析要求,提出基于可拓学原理研究SFEP。首先论述了系统功能状态与可拓学结合的可能性。其次研究了SFEP的可拓表示,确定了SFEP的基本单元,即原因事件—传递条件—结果事件。认为事件可表示为物元和事元的复合事元;传递可表示为关系元和这2个复合事元的复合关系元,称为传递元。最后研究了传递元的发散性、相关性、蕴含性和可扩性,并说明了方法对SFEP分析的作用。论文是通过可拓学研究SFEP的开始,为系统功能状态分析提供智能分析方法和理论基础。

To study the representation,analysis and processing of system fault evolution process(SFEP),the extension theory is proposed,using intelligent theory and meeting the analysis requirements of system function state.Firstly,the possibility of the combination of system function state and extension theory is discussed.Secondly,the extension representation of SFEP is studied,and the basic unit of SFEP is determined,which is cause event-transfer condition-result event.It is considered that the event is a compound action element of the action element and matter element,and the transfer is a compound relation element of the relation element and the above two compound action elements,which is called the transfer element.Finally,the divergence,correlation,implication and expansibility of the transfer element are studied,and the effect of the method on the analysis of SFEP is explained.The research is the beginning of studying SFEP through extension theory,which provides intelligent analysis method and basic theory for grasping system reliability and failure,i.e.system function state.
