Abstract

There are two shortages of traditional AHP method: (a) expert scoring to be absolute and (b) less considering the credibility of expert scoring and the dynamic difference between experts. In order to solve the above-mentioned drawbacks, an uncertain type of AHP method based on expert’s credibility is proposed in this paper. Risk index dynamic weight calculation model is established. In this method, when the expert scores, they use the interval number instead of a specific value to represent the expert judgments. Determine the degree of the experts' credibility according to the similarity and difference between the uncertain type of matrix. At the same time, considering the subjectivity and objectivity of the index weight, determine the dynamic weight. Example analysis shows that this method is reasonable and feasible, and the dynamics weight can reflect the engineering practice.
