一类模糊选择函数的合理性条件程度的研究

摘要

在集合收缩扩张意义下讨论了模糊选择函数的合理性条件程度Fα（C）、Fβ（C）及FA（C）之间的关系,并在此基础上推广了Arrow-Sen定理的程度描述。%This paper introduces the relationship among three rationality indicators of fuzzy choice functions in the sense of contraction-extension：Fα（C）、Fβ（C）and FA（C）,and a degree description of the fuzzy version of Arrow-Sen Theorem was generalized on the above basis.
