摘要:

针对序信息系统下经典优势关系过于严格从而可能导致排序方法失效的问题,首先,提出了容差优势关系的概念并对其相关性质予以研究;然后,基于容差优势关系,给出优势度的定义,并提出基于容差优势关系的方案排序方法;最后,将该方法应用于智能电网的综合评价中。实验结果表明:相比经典优势关系,容差优势关系对数据具有更强的容错能力,排序结果具有较强的区分度。容差优势关系的提出,能有效避免经典优势关系因属性个数较多、属性值互有优劣时可能引起的失效问题。

Abstract:

Concerning at the problems that the classical dominance relation is too strict under the ordered information system which may lead to failure of the sorting method, the concept of tolerance dominance relation was proposed and its relevant properties were studied. Then basing on tolerance dominance relation, the definition of dominant degree was obtained and a project sorting method based on the tolerance dominance relation was proposed. In the end the sorting method was applied to the comprehensive evaluation of smart grid. The experimental results show that, compared with the classical dominance relation, the tolerance dominance relation possesses stronger capability of fault tolerance for the data. And the sorting results have stronger differentiation degree. The proposed tolerance dominance relation can effectively avoid the problem of failure that caused by a large number of attributes and the different merits of attribute values in the classical dominance relation.
