Abstract:

Aiming at a series of evaluation failures in the plane space of the projection method in the multi-attribute decision-making and evaluation problem, a similarity consistency projection decision-making method is proposed. First, the definition of the ideal offset vector is given, which includes the offset degree of the ideal decision and the preference of the decision maker. Secondly, a new comprehensive evaluation function is constructed according to the ideal offset vector. Then the comprehensive evaluation value of each program is obtained according to the projection of the basic steps of the method. The effectiveness analysis shows that the newly proposed method has comprehensive considerations on modular similarity, distance similarity, cosine similarity and direction similarity, so as to avoid the incompleteness of single similarity and the failure of comprehensive evaluation function. Finally, a case study shows that the method is reasonable and effective.

Key words: multi-attribute decision-making, projection decision-making method, similarity consistency, preference coefficient
