摘要
通过一种新的模糊数序关系,首先给出了二元凸模糊数值函数及二元模糊数值函数上半连续、下半连续的定义,其次利用二元模糊数值函数的上、下半连续讨论了二元凸模糊数值函数的判定定理.
Based on the new ordering of fuzzy numbers proposed by Goetschel and Voxman,the definition of convex bivariate fuzzy-valued function and the upper（lower）semicontinuity of fuzzy-valued function are given,some judge theorems of convex bivariate fuzzy-valued function can be obtained.
