Study On The Location Model And System Optimization Of Agricultural Product Logistics Distribution Center In Zhengzhou City

With the agricultural production and the circulation increasing year by year, our society has putting forward higher request safety and quality of agricultural products after national agricultural structure adjustment. According to the national development policy of agricultural products, it's extremely important to speed up the development of agricultural logistics and promote sustained increase in rural incomes and safeguard consumer safety. The location of logistics distribution center plays an crucial role in improving logistics status and controlling the logistics distribution cost in the modern logistics theory. It is to say, the reasonable location is one of the main reasons that could reduce the distribution's costs. With the optimization of logistics distribution center, it's easier to improve the efficiency and make the cycle of equipment operation short. During operation in distribution system of agricultural products, optimized logistics distribution center plays a decisive role in completing agricultural outbound and inbounding, replenishment joint operations.This paper Studies on the location model and of system optimization agricultural product logistics distribution center in Zhengzhou City. Firstly, the paper learned from the study that experts and scholars at home and abroad about the location of agricultural product logistics distribution center and system optimization. Secondly, the cost of agricultural logistics is exorbitant in China. Using the correlative theories and methods of logistics and mathematics, this paper studies on agricultural product logistics distribution in Zhengzhou. This paper does some research on the map, government policy, price, agricultural logistics infrastructure and so on in Zhengzhou. Analysis on these infrastructure and other related factors, this paper elects 18 optional logistics outlets in order to establishing the location model of agricultural logistics distribution center and builds the model into mathematical equations. At last, it could be concluded that there ware 7 agricultural logistics distribution center would be built or rebuilt in Zhengzhou by LINGO software. Thirdly, it is based on Flexsim simulation software that simulation and optimization of the model of agricultural logistics distribution center. This paper has achieved the purpose of system optimization. It modifies parameter of the model by using the functions and features of Flexsim simulation software.Taking leaf vegetables as an example, this paper hopes to simulating the whole operation of agricultural product logistics distribution center system and optimizing the logistics network, reducing agricultural logistics cost and supporting the development of agricultural logistics by theoretical and practical basis.Although this paper makes a systematic study of agricultural product logistics distribution center and system optimization, it still needs to do further research in selecting modeling constraint condition and optimization.
