Optimization of Network Node Layout of Agricultural Products Cold Chain Logistics based on Value Orientation

Abstract

This article defines the relevant concepts of agricultural cold chain logistics, explains the theoretical basis, analyzes the current situation of agricultural cold chain logistics, combs the main evaluation methods of agricultural cold chain logistics at this stage, points out its shortcomings, and chooses based on value orientation research the three-stage model. A two-level planning model for the optimization of the cold chain logistics network of agricultural products is constructed on the upper level. The upper level determines the best cold chain logistics center location; the lower level determines the transportation path of the distribution. The two-level programming model comprehensively optimizes the two key decision goals in the cold chain logistics network of agricultural products at the same time, and then optimizes the total cost of the entire logistics network. At designing a hybrid algorithm combining genetic algorithms and ant colony algorithm to solve the model, the optimal location and optimal delivery route of the cold chain logistics network node are obtained. Finally, the conclusion is drawn through the analysis and comparison of calculation examples. Only by integrating the optimization of location and distribution path in the cold chain logistics network can we reduce the total cost of the logistics network as a whole and optimize the allocation of resources.
