Abstract

The aim of the article is to present a new approach to a derivation of a priority vector form an interval comparison matrix in a group AHP framework. It is supposed that preferences of individual decision makers are aggregated into a group interval comparison matrix, and the priority weights of all alternatives are estimated via the geometric mean method generalized to interval numbers with the use of interval arithmetic. This approach differs from usual solutions of the problem based on linear programming methods or a decomposition of the interval comparison matrix into crisp matrices, followed by the eigenvalue method. This new approach is demonstrated on an example, and a comparison with a standard group AHP is provided as well.
