Research On Some Key Problems In Supply Chain Optimization Of Chain Retail Enterprise

The retail supply chain is a supply chain which is based chain retail enterprises as the core. In fact, it is a part of a whole supply chain and it is the leading chain retail, operating mainly from the pull of consumer demand. The optimization of retail supply chain not only can accelerate consumer goods flowing healthy and rapidly, but also can promote the chain retail's strategy competitive strength, reduce its operating costs and increase its profit margin. In recent years, the chain retail in China as a major business management and organizational forms has been the constant promotion and development. But, the research about the optimization of chain retail is still relatively small, and whether domestic or abroad it is a new research subtopic. On the basis of the investigation and visit of retail enterprises deeply, the dissertation makes an optimized research on several key connections of the retail supply chain. Meanwhile, the dissertation establishes some interrelated optimization models and algorithms, and, design and implement a supplier selection and evaluation software system against BuBuGao Trade Chain Share Co.Ltd applications for background. The main contents and fruits of this dissertation are outlined as follows:Firstly, on the basis of manufacturing company's supplier selection evaluation index system and combining with the chain retail enterprises actual operation results and the survey, the dissertation has designed a more scientific and rational evaluation index system for the chain retail enterprises selecting and evaluating their suppliers. In addition, the dissertation has designed the measuring and quantifying methods and principles for every indicator. Then, based on the index system and considering the factual cooperative relations between the chain retail enterprises and the suppliers, we establish a model based on entropy and plus-minus TOPSIS for chain retail selecting suppliers and a multi-objective integer linear programming model about distribution of purchasing amount in chain retail enterprise. This is one of the main points of innovation.Secondly, based the reality of one chain retail enterprise building one distribution center commonly in one city or in one area, and considering the operation practice of the chain retail distribution center, the dissertation weights on the target situation effect of the gray situation using entropy weight and establishes a discrete location model based on entropy weight and gray situation of the chain retail distribution center. On the other hand, combining with the idea of the gravity method and introducing the concept of attractiveness index of the distribution center affecting the chain stores, we establish an improved gravity sequential location model with the objective function as the maximum value the attraction index. Then, in order to make the optimal solution of the sequential location model having practical application value, we optimize the model using two methods. This is the other of the main points of innovation.Thirdly, taking the fact of chain stores holding a small amount of inventory into consideration and considering the distribution ways of distribution center, the dissertation establishes a truck-load distribution optimization model in one city for chain retail distribution center. The detailed analysis of the solution and the process of solving about the model are given in the dissertation. This is also a point of innovation.Finally, the dissertation designs and develops a software system for chain retail enterprises selection and evaluation their suppliers based on the BuBuGao Trade Chain Share Co.Ltd applications. At present, we have not found a similar software system directly related to chain retail enterprises choosing and evaluating suppliers. When the chain retailers using the software to select and evaluate the suppliers, the user can determine the evaluation indexes and their properties in the system. It is very purposeful and good human-computer interface, and the user can look over the evaluation results and the interim achievements by the window expediently. For the chain retail companies selecting and evaluating suppliers, it provides a better software support.
