摘要
继续 [1]、[2 ]的讨论 ,进一步探讨由 Fuzzy数据资料计算变异系数的问题 ,提出了正有界闭Fuzzy数平均取值大小的评价指标 ,据此而给出了由表示为正有界闭 Fuzzy数的数据资料计算变异系数的计算公式。还给出了数据资料为三角 Fuzzy数和对称形
Continuing the discussion of [1] and [2],this paper deals with the computational problem of the dispersion coefficient of fuzzy valued data. Firstly,we present an index for assessing the mean value about fuzzy valued. Then we develop a technique to compute the dispersion coeffecient of a body of fuzzy valued data which are expressed as positive bounded closed fuzzy number. In this paper, we also give the formula to handle the situation in which the fuzzy valued data are triangular and symmetric.
