Yu Zhenghong · Computer Engineering and Applications Journal · 2012
According to the fuzzy ideal point method,two multiple attribute topsis decision making methods are presented to deal with the fuzzy multiple attribute decision making problems on exponential type fuzzy numbers.First of all,by defining the expected value of exponential type fuzzy numbers,to achieve defuzzification processing of weight vector of attributes;Defining the distance measure between exponential type fuzzy numbers,to calculate the distance between every scheme and ideal scheme.Then,based on the definitions of the expected value and the distance measure,two fuzzy multiple attribute topsis decision making methods are presented from two different points.Finally,an example is provided to verify the feasibility and effectiveness of the proposed methods,and to compare and analyze the two methods.
