A Multi-attribute Decision Making Method Based on Combination of Subjective and Objective Weighting

In view of the subjectivity of subjective weighting method in multi-attribute decision making and the fact that objective weighting method does not take into account the intention of decision makers, this paper proposes a method of weighting based on the combination of subjective and objective information-subjective and objective combination weighting method. In this method, we carried out weighted synthesis to the subjective weight and the objective weight, and used the combination of the two optimization goal programming model-the minimization of deviation square sum between subjective and objective weights, and the maximization of the comprehensive evaluation value of the decision schemes, to obtain weighted coefficients. Finally, we made an example analysis and compared this method with the existing weighting method. The contrast results show that the sorting scheme by this method can reflect both subjective and objective information, which shows that this method is practical and effective.
