Abstract

The trustworthy service selection is a typical multi-attribute group decision making (MAGDM) problem. The aim of this paper is to develop a novel method for MAGDMwithtriangular intuitionistic fuzzy numbers (TIFNs) and apply to the trustworthy service selectionproblem.Firstly, we define the mean-index, variance-index and standard deviation of TIFN. And a new distance measure of TIFNs is proposed and corresponding proofs are given. Based on these concepts of mean-index and standard deviation, a ranking method for TIFNs is developed considering the risk preferenceof decision maker (DM). Further, according to the crisp relative closeness coefficient matrix with respect to the normalized TIFNs decision matrix, we use entropy measure to obtain attribute weights. The DMs weights are calculated by the similarity between the individual decisions and the average decisions. Then, a decision procedure is described to solve the MAGDM under triangular intuitionistic fuzzy environment. Finally, a real trustworthy service selection example is analyzed to verify the practicality and effectiveness of the developed method.
