A site selection model of the grain logistics center was constructed,the factors affecting the site selection process were analyzed,and a site selection evaluation model was constructed by using a neural network improved by genetic algorithm.

A grain logistics center location model based on extension theory is put forward,which applies extension decision method,cluster analysis and gravity method together.

Present state and development trend of grain logistics in China;

Development of GIS-based grain logistics decision-making support system;

On Scientific Operation and Normalizable Management of Grain Logistics;

Then,the model base of the LD_DSS is discussed,the flow of some core problems such as grain distribution centers allocation and the transportation routes planning in the grain logistics distribution system is discussed.

Based on the grain logistics distribution problem of the grain logistics enterprise,combing with the theory and methods of GIS,this paper did the systems analysis of the GLD_DSS(grain logistics distribution_decision support system).

In the process of reforming old industrial bases,it is important to develop food logistics industry and optimize agricultural structure in order to promote old industrial base .
