Study On Planning Method For Logistics Facility In Distribution Network Of Supply Chain

Along with the economic globalization development, our country economic potentiality enhanced, and logistics also develop rapidly, supply chain theory also gradually is accepted by the enterprises and the academic circles. Enterprise has reasonable and highly effective distribution network to be allowed to raise the customer service level, the enterprise competitive ability and the production flexibility and to increase ability thorough new market .Enterprises achieves effective balance between the cost and the service through reduce the stock and enhance working efficiency.Distribution center in the distribution network play the vital role, but the facility location directly affects the distribution network architecture of enterprise and the logistics delivers efficiency, therefore. What this article will discuss mainly is distribution center location research based on distribution network, this is vital significant to develop and consummate enterprise's own distribution network.This article based on great many documents over the world, summary and the analysis to the facility location theory method, give the general process of facility location planning of distribution network. Combined with the actual problem ,the article has confirmed the accuracy and the feasibility of the model.The paper altogether divides into six chapters, among which chapter3 to chapter5 is the main component .The content of the six chapters goes as follows:Chapter1: Introduce the background, the research goal and the significance, the internal and external status and the structure arrangement and the technical route of this research.Chapter2:On the basis of the existed conceptions of distribution network, the article analyzed the reason which the network produced , the types,the function and the superiority of the distribution network and so on. And it gives the main content of planning of distribution network and introduces the key problem which the article wants to study. It laid the foundation for distribution network facility location model in later chapters.Chapter3: Premise of facility location is to carry on the analysis to the market demand. Firstly enterprise must grasp the primary factor influence the demand of market. Secondly enterprise ought to choose the reasonable forecast method to forecast exactly. In order to increase the accuracy, it summary and analysis the forecasting method and produce the multiple regression analysis,exponential smoothing and gray forecast method .The chapter put forward the combination forecasting method. Use practice data to execute the forecast for the demand of product, which proved the feasibility of using this forecast to increase the accuracy of products'requirement.Chapter4: This chapter summaries has analyzed the existed theory of facility location and carried out further study to the facility location model and method. The writer analyzed the principle and the influence factors of the facility location in the basis of reading many literature and produced appraisal target system of the facility location, and put forward the triangle fuzzy AHP synthetic evaluation model and introduced the risk decision-making coefficient in the triangle fuzzy arrangement .An example is presented to validate the feasibility of this method.Chapter5: The chapter put forward the cost model of distribution network facility location, which based on cost smallest principle of the transportation .It considered the cost, the demand and the fuzzy chance constraint of the deliver time, and the fuzzy chance constraint are transformed to 0-1 mix integer programming question by clear disposal. This chapter introduced distribution network model with single factory, the multi- products, distribution center, multi users, and obtained the optimal solution through the lingo software, which confirmed feasibility and the accuracy of the model.Chapter6: The summary of and forecast. The chapter summaries research results, the innovation spot and the outlook of the future research. To sum up: the innovative aspects of this thesis include the following aspects:1.Summary and analyze the theory of facility location ,give the appraisal target system of distribution center location , and put forward the triangle fuzzy synthesis appraisal model of distribution center location. And the article introduced the risk decision-making coefficient in the triangle fuzzy number arrangement, which considered risk bearing ability of the policy-maker when choosing the plans . Establish the cost model distribution center location, and introduce the fuzzy chance restraint of deliver time in the model, and transformed the restraint to mix integer programming question by clear disposal .On the whole, this article belonged to the exploring study of model and method in facility location of distribution network. And the main aim lies in to create or innovate the method of facility location. Although theory of facility location already had the rich research fruits, including qualitative and the quota method research. This article was only conducted the exploration research in the foundation, but also there are more problems related need further study.
