A Study On The Reverse Logistics Network Fragmented Agricultural Products

In the 21 st century, China’s economy has made remarkable achievements, but China is still an agricultural country, the agricultural economy is still lagging behind the stage; However, agriculture is a matter of national economic livelihood of the important economic sector, the level of development of the development of our national economy has a significant impact, "three rural" issue is an important issue affecting the development of our national economy. Currently, the agricultural economy shifted from production areas to circulation areas, though our agriculture has made great strides in the development of production, the logistics of low levels of its agricultural products, distribution costs remain high, which became an constraint factor in development of the agriculture.From the logistics chain to solve the agricultural problems is a more effective way;how to improve logistics efficiency and reduce logistics costs of agricultural products, improve logistics and value-added agricultural products in circulation, to protect the interests of producers and consumers of agricultural products, so as to increase farmers’ income and promote agricultural economic development improve the international competitiveness of agricultural products, so in-depth study of the logistics system of agricultural development for the agricultural economy has important theoretical significance and application value. With the development of market economy and increased competition, the market appeared many varieties of mass production, and consumption of large-scale, low-volume, diverse dual trends, in particular, most of the agricultural products presents Fragmented, sales difficulties waste of resources and other characteristics; How to solve these problems, so as to promote agricultural production and farmers’ income, an effective solution to the waste Fragmented agricultural products, increase market supply of agricultural products, has become a hot issue in the country. China is now a wholesale market for agricultural products, such as the core of the agricultural logistics model, third-party logistics model farm, farm supply and marketing companies, logistics and distribution model to solve the distribution of agricultural products in large quantities, and for small quantities, is not fragmented agricultural related the study; That "support for small agricultural origin gather market, collecting and distributing center construction", Government departments also file "CPC Central Committee and State Council on Accelerating deepen rural reform a number of opinions agricultural modernization"; Ministry of Commerce, Development and Reform Commission, the Ministry of Agriculture and other 13 ministries jointly issued "to further strengthen the national agricultural market system of guidance," clearly "planning and construction of a number of national, regional and rural farms of origin and other markets." In this paper, a broad-based reverse logistics, reverse logistics building fragmented agricultural open-loop network structure is proposed to build the factors to be considered agricultural reverse logistics, reverse logistics network build farm structures and processing, point out the agricultural reverse logistics network structure should contain four levels: agricultural recycling center, reprocessing centers, distribution centers, processing enterprises. This paper established a reverse logistics network based model to build fragmented agricultural achieve minimum cost of reverse logistics network as the objective function, and an improved particle swarm algorithm to obtain the optimal solution of the model. Finally, a vegetable processing company of Shenzhen carrys out the empirical study, in order to verify the effectiveness of the reverse logistics network model, and proposed building schedule and implementation of a regional agricultural Shenzhen reverse logistics network based model reflects problems proposals to resolve the acquisition of fragmented agricultural products- sales questions, to achieve seamless fragmented agricultural produce and sell the land.
