Research On Logistics Distribution And Its Algorithms Of Rural Region Chain Supermarket

Owing to the support of the government and the development of rural economy, "farm shop" has developed rapidly in the counties. However, it is restricted by the decentralized management and its logistics level. With the expansion of the "farm shop" and the increasing consumption demand of the farmers, in order to accelerate the development of" farm shop", according to the chain operation theory, it is necessary to carry out chain operation and unified distribution. The chain operation has more advantages, such as scale effect, brand effect etc, the unified distribution will reduce transportation cost and strengthen the competitiveness of the chain "farm shop". Based on the background above, this thesis just take logistics distribution and its algorithm of the rural county of the supermarket chain as subject, study and explore these problems: the necessity for the rural county of China to develop the supermarket chain, the solution to logistics and distribution of supermarket chain in rural areas, the best choice, the analysis and choice of the algorithms of logistics distribution, the model-saving algorithm and its improvement of vehicle routing problem. etc.First of all, the thesis analyzes the necessity of chain operation on the base of the chain operation theory. Then the thesis analyzes the status in quo of "farm shop", the reason why we carry out chain operation, constraints and so on, thus we can conclude that we must carry out the chain operation in order to develop the "farm shop". The establishment and development of chain supermarkets in the country, the realization of advantages of the chain require the efficient logistics and distribution. In consideration of the status in quo of logistics in counties, this thesis has given the comprehensive explanation of logistics distribution program of"farm shop"in counties, and further indicates that it is urgent to induce the development of strong retail chain enterprises range from cities to countries, execute a unified chain of distribution, regardless of chain or unified distribution. For chain operation of "farm shop", the retail chain enterprises with strength in cities are a prerequisite for the implementation of uniform distribution. Just in this premise, this paper sum up and analysis the algorithm of vehicle routing problem, then improve the decreasing running planning in heuristic algorithm, using it generate a group of data randomly, then the thesis analysis the data, finally, elicit the program of the logistics distribution.
