Abstract

In this paper, we propose a method to group similar membership functions, each of them representing the opinion of an expert, to obtain a resulting membership function that represents alike opinions among a group. The similarity is based on the shape characteristics of membership functions used to represent the expert opinions on a specific criterion. There are several applications for the proposed method which include group decision making, suitability analysis and consensual processes. In each of these applications diverse points of view are present. The goals of the method are to detect similar membership functions, to establish a manner that allows the selection of representative opinions and to obtain a result membership function that represents a specific trend or a suitable concept for a group of similar membership functions. Our approach is based on soft computing techniques, considering expert preferences as a matter of degree, including a novel method to process similar opinions with more ease.
