摘要
论文介绍了系统因素结构反分析子框架(inward analysis of system factor structure,IASFS).它是为了解系统在工作环境因素变化过程中系统可靠性的变化.论文根据其对应关系进行逻辑推理得到规则,进而形成系统等效响应结构.得到适合系统工作的因素状态组合.IASFS是笔者提出的SFT框架的一部分.根据IASFS的特点定义了01型空间故障树,其结构化表示法为图法和表法.基于表法的IASFS方法有逐条分析法和分类推理法.论文主要定义和描述了逐条分析法和分类推理法.说明了IASFS是一个系统结构反分析人机认知体.推理结果表明,就系统与因素的状态关系而言,系统结构为T=A_1·A_4+A_3·A_5+A_1·A_2·A_3.逐条分析法和分类推理法可得到等效响应结构,其与被分析系统对工作环境因素变化响应相同.
This paper introduces the framework of inward analysis of system factor structure (IASFS). It is for understanding the changes of the system reliability in the process of the change of environmental factor, which the system works in. The thesis carries on the logic inference to get rule, according to its corresponding relationship, and then the system equivalent response structure is formed. The combination of factors that fit the system work is obtained. IASFS is part of the SFT framework proposed by the author. According to the characteristics of IASFS, 01 space fault tree is defined, and its structure is represented by graph method and table method. The IASFS method includes the item by item analyses (IIA) and then classification reasoning method (CRM) in the table method. The paper mainly defines and describes IIA and CRM, and gives a mathematical description. It is described that IASFS is the human computer cognitive body for inward analysis of system factor structure. The results show that for the relationship between the system and the factors, the system structure is T = A1 ·A4 + Aa · A5 + A1 · A2 · A3. IIA and CRM can get the equivalent response structure, which is the same as the response of the analysis system to the change of the working environmental factor.
