Research on Enterprise Optimization Scheme based on Grey Correlation Entropy Weight Method and Multi-Objective Programming

Abstract

This paper establishes a comprehensive evaluation model based on entropy weight method and grey correlation analysis method, quantifies the importance of each supplier to the enterprise, and finally gives the ordering and transportation plan of the enterprise in the next 24 weeks. Firstly, four indicators reflecting the characteristics of suppliers are mined based on the order quantity and supply quantity. Then the entropy weight method is used to calculate the weight of each index, and the two methods of normalization, weighting and grey correlation analysis are directly quantified respectively to obtain the most important 50 suppliers. After comparison, it is found that the 5-year supply quantity of suppliers obtained by the entropy-grey correlation analysis model is 4302,643m3, accounting for 97.79% of the total supply quantity of 204 suppliers, which is 3.3% better than the result obtained by direct entropy weight method. Then, the supply quantity of the next 24 weeks is obtained through the time series prediction model and statistical analysis method, and the minimum number of suppliers is 37, as well as the corresponding ordering and transportation plan of the next 24 weeks, and the plan is analyzed through visualization.
