Research On The Optimization Of Cold Chain Logistics Distribution Path Of Fresh Products In Mudanjiang City

With the rapid development of the economy,the quality of life of China’s urban residents has improved significantly.The diet structure has also changed with the increase in per capita income,and a wide variety of fresh produce has become a necessity for daily consumption.Due to the quality characteristics of fresh products,differences in origin and seasonal differences in production need to be supported by the corresponding cold chain logistics system in order to meet the needs of consumers.In the cold chain logistics system,besides the foundation of cold chain facilities and equipment,the selection and optimization of the distribution path is an important aspect to reduce the logistics loss of fresh products and improve consumer satisfaction.Firstly,based on a review of the current situation of domestic and international research on cold chain logistics and distribution path optimization of fresh products,the research content and ideas of this paper are proposed.Secondly,the concepts and theoretical basis related to cold chain logistics,fresh product logistics and distribution path optimization are explained.And the various types of algorithms for path optimization are also analyzed and compared,and a combination of simulated annealing algorithm and genetic algorithm is chosen for the subsequent study.The focus of this paper is to analyze the current situation of cold chain logistics of fresh products in Mudanjiang City,find out the problems of cold chain logistics distribution among them,and construct a cold chain logistics distribution path optimization model.Take a representative fresh produce distribution center as an example,and measure it according to the actual condition and specific location information of the distribution center and the demand network.Then,the simulated annealing genetic algorithm is applied to solve the model by MATLAB software to obtain optimization results and verify the feasibility of the model.Finally,propose the management suggestions to ensure the implementation of the cold chain logistics distribution path optimization scheme for fresh products.This paper studies the optimization of the cold chain logistics distribution path of fresh products in Mudanjiang City,which not only solves the application needs of real enterprises,but also provides ideas and methods for solving similar problems in the industry,and has certain promotion and reference values.
