Decision-Making Model Based on Weighted Norm

摘要

In this paper, based on the classical grey relational decision, the relative closeness degree is calculated by using the weighted norm, and then the decision result is obtained. First, the weight of each indicator factor is determined by the degree of influence of various real factors, which gives the weighted norm. Second, the weighted norm is utilized to calculate the distance between the ideal scheme sequence and the selected one. Finally, the optimal scheme is chosen according to the relative closeness values of the selected scheme. The weighting method in this paper is adapted to subjective and objective factors, which makes more reasonable and flexible decision-making results, and becomes more convenient to choose for decision-makers.
