摘要
给出模糊数的质心值的概念,讨论其运算及性质,并基于模糊数的质心值和离散度在模糊数空间上构造了2个用来排序模糊数的弱序二元关系.
In this paper,we give the concept of centroid value of fuzzy numbers,and discuss its operation and properties.And then,based on centroid value and dispersion degree of fuzzy numbers,we construct two weak ordered relation used for ranking fuzzy numbers in the fuzzy number space.
