In this paper, aiming at the defect of the original entropy weight calculation formula, this paper proposes a multi-objective decision making method which improves the entropy weight calculation method. Based on the single weighting method of the original entropy weight calculation formula, this method adds a complementary weighting method, and uses the mean value of the entropy value of each evaluation index to control the proportion of the two weighting methods, and combines the subjective weight of experts to get the comprehensive weight. Different entropy value types are tested to verify that the proposed method is more reasonable, in addition, this paper also takes Pareto solution set as an example to verify that the proposed multi-objective decision making method based on the improved entropy weight calculation method is feasible, simple and efficient, and more suitable for online operation.
