| Recent years, logistics, as the "third profit source", has been developing rapidly in our country. And it became more and more important for many companies. And the delivery routing problem has become the most important part in many researches to lower the cost of the distribution.GIS(geographic information system) is a system constituted by hardware, software, data. It will support us to get, manage, operate, analyze and display the geographic space data. So we can use it to handle some complicated programming and management problems.This paper applied the technology of GIS to the logistics system to help us to resolve the problem of delivery routing. Firstly, this paper study on the concept and development history of the logistics and GIS, and point out the feasibility of the combination of the tow technologies. Secondly, according to the actual demand, this paper research various delivery routing algorithms and do some enhancement on them, and give the results of the experiments. Thirdly, this paper allied GPS\GPRS technology to this system. Thus, dynamic routing programming can be achieved. Fourthly, this paper constructed the general network model based on the GIS, and enhanced the GIS general development framework. Thus RGUDF can support the general functions of delivery routing. Finally, this paper brings forward the whole design of the logistics based on GIS. |
