    Abstract
  • In order to improve the efficiency of initial solution for vehicle routing problem(VRP), the spatial characters of demand points for hands-free travel system in Shanghai World Expo were studied under uncertainly conditions.Vehicle routing method was put forward based on the spatial characters, and the Single-LINkage(SLINK) clustering method for the spatial characters and the estimation method for the clustering analysis result were built.Computation result indicates that the Single-LINkage clustering method can get the total distance of 583 for the initial solution, and the SWEEP method gets 595 when the demand points are clustering, so the analysis of spatial character for demand points contributes to the last solving for the VRP under the uncertainly conditions.
