Group decision making for weapon systems selection with VIKOR based on consistency analysis

摘要

Weapon systems selection is an unstructured, complex multi-criteria decision analysis problem with a wide range of considerations. In this paper, a hybrid approach which uses VlseKriterijumska Optimizacija I Kompromisno Resenje in Serbian (VIKOR) technique, is presented for the screening of weapon systems. More specifically, a group of experts are first asked to make judgments on the criteria using fuzzy preference relations. Next, the experts are assigned different weights directly based on their opinions with consistency analysis, which is one of the main novelties in this paper. A collective comparison matrix is then constructed and the weights of the criteria are determined based on the dominance concept. VIKOR is used to rank and determine the best alternative. A case study demonstrates the usefulness and effectiveness of the proposed approach, in comparison with the technique for preference by similarity to ideal solution (TOPSIS).
