Research on Real Time Computer Simulation System of Urban Logistics Distribution Vehicle Routing Optimization Based on GIS

Based on GIS as the main carrier, our real time computer simulation system of urban logistics distribution vehicle routing optimization precisely measures and marks the information of distribution site, providing true and available information for routing optimization, performing low cost and highly efficient operation on vehicle scheduling by the distribution center through optimization algorithm. The system can satisfy the demand of urban logistics distribution routing optimization under the multi- constraints condition of variable distribution cites and complex urban roads by simulating numerous distribution cites up to scores of thousands according to different plans and different regions and counting the information of vehicle routing and loading by different plans for contrast analysis so as to adjust and optimize the distribution routing, regions, period and vehicles in order to accomplish the equilibrium distribution and management of many relevant indexes such as vehicle load capacity, distribution work capacity and distribution time.
