Fuzzy Group Full Consistency Method for Weight Determination

摘要

In this paper, the FUll COnsistency Method (FUCOM) is extended to workin a collective manner, to solve a fuzzy optimization problem and to obtain the fuzzyweights of criteria. The employment of a predefined order of criteria decreases thenumber of fuzzy comparisons needed in the evaluation phase. The defuzzified valuesof the optimal weight coefficients are calculated by Graded Mean IntegrationRepresentation formula. This feature also reduces time complexity without affectingthe quality of the solution. Two practical examples are presented to verify thereliability and feasibility of the proposed fuzzy group FUCOM. The obtained resultsdemonstrate that the new fuzzy group weight determination method can obtainappropriate criteria importance.
