Research On City Logistics Distribution Route Optimization Based On GTS System

Logistics distribution system optimization is a use of system theory and mathematical modeling of the structure of high quality distribution route and distribution tools of transportation and management, its advantages is using the shortest route, the practical link, the fastest speed and the lowest cost for distribution. Distribution is the most important elements of the logistics industry, it has the pivotal status and the function, it reflects the logistics in the final result, communicate with customers, to meet customer requirements, the social and economic benefits of logistics activities is the important results in the distribution process. The appropriate distribution route choice not only has the important function to the raise the distribution efficiency, but also helps save the enterprise the cost, is advantageous to the enterprise the normal and stable development. The modern logistics distribution system based on GIS can be analyzed by the integration of spatial attributes.. Through the spatial management and analysis function of GIS system, it greatly promotes the scientific research, visual management and information degree of logistics distribution system..This paper first analyses the existing in our city and the current situation of logistics distribution problems; secondly the GIS related theory were introduced and analyzed the superiority of the logistics industry into the GIS; after the introduction of the saving method of the shortest distance tour delivery optimization problem of Dijkstra algorithm and vehicle running route, method, and the shortest path problem optimization algorithm combining with GIS system, create a Dijkstra optimization model based on GIS system; finally, the GIS system Dijkstra optimization model is applied to the Yizhuang area of logistics distribution route optimization based on case analysis, results show that:using GIS Dijkstra optimization algorithm for Yizhuang area logistics transportation route optimization based on the distribution of the distance, smaller, lower costs, loss of income increase. The research results prove that the Dijkstra optimization algorithm based on GIS system has more advantages than the traditional optimization algorithm.. The research of this thesis has some reference value for improving the efficiency of urban logistics distribution and promoting the application of GIS system in urban logistics.
