针对权值是区间数且指标值以三角模糊数形式给出的模糊多属性决策问题,基于格序决策的理论,提出一种新的格序决策办法.方法通过计算梯形模糊数的中心将TOPSIS方法推广到了模糊数的领域,进而给出一种新的方案排序方法.
Aiming at the fuzzy multi-attribute decision-making problem whose weights are interval numbers and the index values are given in the form of triangular fuzzy numbers, a new method of lattice decision is proposed based on the theory of lattice decision making.Methods By computing the center of trapezoidal fuzzy numbers, TOPSIS The method is generalized to the field of fuzzy numbers, and then a new method for sorting programs is given.
