基于贴近度的模糊综合评判结果的集化

The definition of product about fuzzy comprehensive evaluation methods based on closeness

在分析各种贴近度概念的基础上 ,对贴近度进行分类 ,证明了两种对称贴近度定义的关系 ,讨论了择近原则与最大隶属原则的内在联系 .随后构造了两种非对称贴近度 ,证明了它们的性质 ,给出了相应的算法 ,在一定程度上解决了最大隶属原则失效情况下的评判问题 .

Closeness degree is classed on the basis of analyzing various definitions for closeness degree. At the same time,the relationship of two species definition for symmetric closeness degree is proved;the inherent connection between selection nearness principle and maximum subordination principle is discussed. Then,two kinds of non-symmetric closeness degree are constructed,its characters are proved,and the corresponding algorithms are given too. This solves problem about evaluation partly when maximum subordination principle is ineffective.
