THE EXTENDED TOPSIS METHOD WITH INTERVAL-VALUED FUZZY SETS AND EXPERIMENTAL ANALYSIS ON SEPARATION MEASURES
Ting-Yu Chen (Taiwan) and Yi-Wen Li (Taiwan)
Abstract:
The theory of interval-valued fuzzy sets has been developed and has been received valuable applications in the field of multiple attribute decision analysis. The purpose of this study is to extend the concept of TOPSIS methods for solving multiple attribute decision making problems with interval-valued fuzzy data which are capable of coping with imprecise information due to the fact that exact data may be difficult to be precisely determined since human judgments are often vague under many conditions. An experimental analysis is conducted to compare preference order by different separation measures that calculate the distance between the alternative and its positive-ideal and negative-ideal solutions. The consistency rate, the contradiction rate of the best alternative, the inversion rate between the better alternatives and worse ones, and average Spearman correlation coefficients are utilized to conduct a pairwise comparison for all separation measures. The results which are inclusive of 100 combinations of 10 different categories of number for each alternative and attribute indicate that the preference orders are hardly identical using different separation measures in the interval-valued fuzzy TOPSIS method.
Keywords and phrases:
interval-valued fuzzy set, multiple attribute decision analysis, TOPSIS, experimental analysis, separation measure.
