A Model of Based on Z-number and Fuzzy Analytic Hierarchy Process

Abstract. Although the Fuzzy Analytic Hierarchy Process is on e Multi-Criteria Decision Making techniques, it does not consider the reliabi lity of information. The Z-number contains both uncertain variable and its reliabilit y, which has been applied to uncertain environment including decision making, risk assessm ent, linear programming etc. In this paper, a new method of Multi Criteria Decision Maki ng based on Z-number and Fuzzy Analytic Hierarchy Process is proposed, where the e valuation of each alternative with respect to each criterion is described as a Z-numbe r, including both the evaluation and its reliability from evaluators. Finally, a practical e xample illustrates the steps and effectiveness of the method.
