Research On The Optimization Of Farming-supermarket Docking Routing Of Fresh Agricultural Productsbased On The Freshness Controling

A prominent problem in the development of China’s agriculture is fresh agriculturalproducts having a high circulation cost, low marketization level and large wastage. Inaddition, transport time and quality of fresh agricultural products led to a low freshnessof fresh agricultural products. A series of problems weakens the competitiveness of freshagricultural products market in China and becomes the bottleneck of agricultural productcirculation system in our country. So our country puts forward an operation mode offarming-supermarket. Although this operation mode can reduce circulation link of thefresh agricultural products, but it can’t solve the redundancy problem in fresh agriculturalproducts circulation. It still exists more waste Farmers and in the shipping of farmers andsupermarket. The problem of controlling the freshness of fresh agricultural products andlow distribution efficiency should be solved. Therefore, the dissertation choice:optimization the path of fresh agricultural products farmer-supermarket docking based onfreshness control.Previous research on path optimization didn’t considerate the relationship amongfreshness of fresh agricultural products, transport cost, cargo damage cost, punishmentcost and profits. So it often pursuits the lowest distribution cost and doesn’t consider theinfluence of the distribution path to agricultural products sale in supermarket. This paperestablishes a path optimization model based on freshness and solves the model usingparticle swarm optimization algorithm. Then it discusses the practical application of thismodel in a supermarket A. Concrete research content is as follows:First, on the basis of defining the basic concept of agricultural production, this paperbriefly introduces the related theory of farming-supermarket docking, fresh agriculturalproducts logistics, the vehicle routing with time windows and particle swarmoptimization. It lays a theoretical basis for discussing the dissertation. Second, This paperanalyzes the several current distribution models of fresh agricultural products in Chinaand points out the main problems in the process of fresh agricultural products distributionin China. And then, on the basis of analyzing path optimization problems and constraint of the fresh agricultural products in farming-supermarket docking, this paper putsforward a new conceptual model and establishes a path optimization mathematical modelof fresh agricultural products in farming-supermarket docking based on freshness, anddiscusses the PSO algorithm in solving the problem of the implementation of themathematical model. At last, this paper optimizes the fresh agricultural productsdistribution path of farming-supermarket docking in the supermarket A.
