Determining the weight of evaluation index based on FAHP and evidence theory

Abstract

In the multi-objective decision-making problems, the weight problem research occupies a very important position. The weight is the quantitative distribution of the different aspects' importance of the object to be evaluated, and the weight of each evaluation factor in the overall evaluation is differentiated, and is of great significance in practice. In this paper, by using the fuzzy analytic hierarchy process (FAHP) combined with the evidence theory though to determine evaluation indexes' weights. First, we use FAHP to acquire the subjective weights of different experts. Then, using the evidence theory to adjust subjective weights and getting the final assessment indexes' weight value. Finally, we prove the feasibility with the example of teaching evaluation indexes weight. Through the introduction of fuzzy hierarchy evaluation and evidence theory. And providing a new thought of evaluation indexes weight confirmation. It has a great application prospect in the research of evaluation index weight determination.
