An Integrated of Fuzzy Rule Base System and TOPSIS Technique for Multi-Attribute Decision Making

Abstract

Multi-attribute decision making (MADM) is one of important issues in make-decision have been conducted many research in recent years. Indeed, the main objective of this research is developing an extended Fuzzy rule based method based on TOPSIS conventional technique. This paper aids to solve a MADM problem by means of fuzzy environment under a group decision making. To do so, fuzzy rule based system (FRBS) is used to obtain final score of alternatives toward each individual expert's opinions. And also, TOPSIS technique is used in order to final aggregation of expert's results and makes a unique decision. This study makes an investigation on data about a supplier selection problem (SSP) as a case-based problem has been taken from a valid research. Robustness and validity of the proposed method is indicated with a numerical example, and compare the output of results with another validated approach.
