The Research Of Distribution Centre Location On HGA

In recent years,the connotation of distribution has been changed a lot. It has been a rising in dustry from ordinary delivery goods to the ways of promote sales and step into the stratagem of competition. In the meanwhile, distribution ask for a higher requirement in building the delivery center, as for the expanding of the distributing area, the promoting of centralize and the diversify ways of delivery. It is a strategic problem in planning distribution center,also it is a new topic worthwhile to be researched, which refer to how to choose the appropriate website.Constructing the appropriate selected location model is allocates and dispatches central selected location the committed step, whether the solution method is the model using in the practice guarantee. The paper takes the national related policy as the basis, and takes the modern allocation which consummates day by day as the idea. The union allocation center selected location characteristic, according to scientific, practical, operational strong principle, to allocated and dispatched in the central selected location the model construction and the solution method, and two key questions has conducted the research. In constructing the DC selected location model, the paper studied the DC selected location basic philosophy and the flow, analyzed several kind of commonly used DC selected location method insufficiency, proposed a future period of time's demand as the foundation, improved all-in cost computational method, and studied the allocation center service level time question, had determined the model prerequisite, has constructed the consideration time question multi-level DC selected location model; In the solution method, has studied the genetic algorithm good and bad points, proposed the algorithm mixed strategy, has designed the HGA solution plan, has studied HGA in the DC selected location model application. Finally, the union actual case the computation theory which and the model proposed to the present paper carries on the application, finally had indicated proposed method and model usability and accuracy.This paper's research may satisfy the allocation center from the cost and the service goal. Constructing the allocation center for our country Government Related Department as well as the enterprise to provide the reference, have the good theory value and the practice value.
