中文摘要：

为了解SFT中元件表现出的在研究区域范围内整体的重要性,定义了元件区域重要度概念.元件区域重要度是在元件概率重要度分布和元件关键重要度分布的基础上对两个分布关于其所在空间维度因素进行积分所得到的.考虑到DSFT处理数据的特点,引入了模糊结构元理论对元件区域重要度进行了结构元化表示.以便DSFT所处理的结果可以更充分的表达原数据的离散分布特点,进而分析得到结果的置信度.给出了元件区域重要度的概念及构造过程,进而给出了引入结构元E表示的元件区域重度的构建思想、过程和具体步骤.

英文摘要：

In order to study the components importance in the all scope of the study in SFT, the components area important degree is defined. Components area important degree is based on the component probability importance degree distribution compo- nent critical degree distribution, they are obtained by the integral of the two distribu- tions on its space dimension. Considering the characteristics of DSFT data processing, introduces the fuzzy structured element theory, components area important degree were structured element representation. For DSFT processing results can be discrete distribution characteristics of the original data of the full expression, and analysis to obtain the confidence level. The concept and construction process of important degree of the element region is given, and gives the construction thought, severe process and concrete steps of components area important degree with structure element E.
