Abstract:

In multi-objective decision, the problem of computing the weights of the indexes is usually considered In view of the shortcomings in the existing techniques, this paper proposes an improved weights determination method by the efficient combination of the entropy weight method (EWM) and the analytic hierarchy process (AHP). In the presented method, the amalgamation is firstly carried out between the objective weights of underlying indexes by EWM and the subjective weights of indexes on the sub-criterion level by AHP. The obtained weights of indexes are synthesized subsequently with the weights of upper indexes. After normalization, the final weights of indexes are obtained. The results show that the final weights by this presented method have higher reliability.

Key words: multi-objective decision, analytic hierarchy process, entropy weight method
