Auto Parts Distribution Center Location Study Based On Bi-level Programmingin

Shanghai Automotive Group Company port passenger vehicle plant and distribution center currently exist due to the initial construction of the distribution center at the decision-making improper distribution of high operating costs caused by poor siting issues, and the resulting distribution is not timely distribution center, enabling customers to stop production lines exist the question of risk. To solve this problem, consider the establishment of a transport costs and the ability for the operation to meet this level programming model. Two aspects of its site plan involving designers and users throughout the network. In the upper level of the objective function minimizes the supplier- distribution center- customers total logistics costs, bringing the total lowest cost; the objective function of the underlying planning, minimizing logistics costs customers.The main content of this paper includes the following aspects: First, from the distribution center, discusses the logistics and distribution center level programming model study abroad, summed up the reason and function to produce auto parts logistics center, and analysis SAIC existing logistics operation mode. Then on common logistics center location methods were studied and discussed and studied Shanghai Automotive Group Harbor passenger vehicle plant distribution center location of the objectives, principles, factors and processes. Then for the Shanghai Automotive Passenger Vehicle Company port facility and distribution center currently exist inappropriate siting lead to higher operating costs and delivery is not timely issues, using a bi-level programming model that, in order to determine the conditions under bi-level programming model for starting point, bi-level programming model proposed fuzzy environment, is solved using genetic algorithms. Finally, the actual case of enterprises, the model was analyzed, and the results are the effect of site analysis, to solve the distribution logistics distribution center operating costs due to higher existing problem is not timely.Auto parts distribution logistics is an important form of logistics and logistics location problem will determine the efficiency of automotive logistics planning and scheduling, and has important theoretical and practical significance of the research. An important prerequisite for the car companies want to reduce costs, increase revenue, and enhance competitiveness is to build efficient logistics and distribution center. Research automobile distribution center location problem, determining the optimal method by rational distribution centers, and to determine the scale of the problem has been the renovation and expansion of the distribution center, can provide a strong reference for the development of automobile business. Research for this paper, Shanghai Automotive Group passenger vehicle plant Harbor practical problems currently facing the distribution center, were analyzed and solutions to improve for the future distribution center location SAIC has laid a solid foundation.
