Ganzhou Agricultural Products Optimization Of Cold-chain Logistics Distribution Routing Based On PSO

With the rapid development of national economy and the rising of people’s living standards, there is an increasing demand for daily food. Nowadays, the market for agricultural products, customers demand is much more diversified and efficient cold-chain logistics distribution service is required.The statistics show that, the need of perishable foods’ transportation and distribution is about forty million tons in our country every year, addition to the incomplete fresh agricultural cold-train system, the transportation and sales of 90% of meat, 80% of aquatic products, large quantities of fruits and vegetables, milk, bean products, eggs, etc have largely remained in the absence of refrigeration equipment distribution, this is largely caused by agricultural decay and waste. Logistics distribution is the most key link for agricultural product circulation, while there are a number of problems in agricultural products distribution, mainly in the following respects: uncertain of delivery time,high distribution costs, high empty loading rate, and so on. In this instance, common people have to face unfavorable condition, such as low freshness, high rate of damaged cargo, high price, and unstable supply. Therefore, company which engaged in agricultural products cold-chain distribution rationally designs vehicle distribution scheme, on the one hand can effectively reduce the products’ distribution costs, on the other hand, can ensure the agricultural products’ quality and safety. Study on distribution routing optimization for Ganzhou agricultural products in a certain area within the scope of the cold chain logistics distribution path optimization gradually transition to the macro level, that is significant to control cost and improve service and has a certain practical research value.Firstly, this paper reviewed the research status of agricultural products cold-chain logistics, optimization routing of cold-chain logistics distribution, and PSO from home and abroad. Then, expounds the concepts and features of logistics distribution, cold-chain logistics distribution and agriculture products cold-chain logistics distribution, and introduced the PSO’s principle and algorithm flow. Secondly, established the Ganzhou agricultural products optimization of cold-chain logistics distribution routing model, based on the analysis of Ganzhou agricultural products cold-chain logistics’ development status and its distribution routing’s main pattern. Thirdly, the PSO were improved respectively from the parameters such as inertia weight, convergence factor, learning factor, and the improving process was introduced. In addition, this paper simulated Ganzhou YQ’s agricultural products distributioncenter through the MAT LAB 2012 a platform, the results proved that the improved PSO can effectively obtain the best scheme about the optimization of agriculture products cold-chain logistics distribution routing. Besides, the specific optimization countermeasures were propounded in combination with the practical situation of Ganzhou agriculture cold-chain logistics.
