Urban Delivery Distribution Routing Optimizing Key Technology Based on Web GIS

Development of information technology, can provide efficient, safe, convenient support platform to logistics and distribution companies, improve logistics and distribution of economic benefits. The problem of the lack of geographic information and the actual line with the calculation of line, distribution routing optimizing, the introduction of Web GIS, and research key technologies. First, given a graphical Web GIS which based on distribution routing optimizing; secondly, study distribution routing optimizing algorithm, including model representation and reverse dynamic programming algorithm; again, study spatial data representation and data structure, including vector and raster data structure; then, study the structure of Web application framework, in the description based on the MVC framework, Spring MVC framework focuses on the component structure; finally, realize the Web GIS technologies, including Java Applet major technical analysis and implementation techniques.  The results show that Web GIS technology will be combined with optimization algorithm on the city line distribution routing optimizing, is technically feasible, has some theoretical and practical prospects, an important future research direction.
