An improved method of aggregation in DS/AHP for multi-criteria group decision-making based on distance measure

Shuang Yao, Guo Ya-jun, Wei-Qiang Huang

Abstract

As a nascent method of multi-criteria decision-making with uncertainty, DS/AHP is structured similar to the analytic hierarchy process(AHP) and its analytic processes are based on Dempster-Shafer theory. While it is unsuitable to make0stand for the missing information during the construction of knowledge matrix in DS/AHP. Therefore, some improvement work is done for DS/AHP. The improved method is used in group decision-making to study the method of fixing the weighting vector for individual members of a decision-making group. Particularly, by regarding the collective distance measure as induced variable, the weighting vector of group members is given and themajority ruleof group decision-making is used.
