| At recent, logistics is an important industry and a new increased in our country's economy. In this paper, the statistics of logistics in our country and abroad is analyzed. After the disadvantages of traditional logistics is analyzed and researched on the new characteristic of logistics management and new model of logistics, a new logistical model based on distribution center is introduced.Vehicle Routing Problem (VRP) is an important problem in physical distribution, how to decrease the distance of distribute car is effective method to saving cost of physical distribution. The Ant Colony Algorithms is a new method for optimization, which is based on the research on the ant's find food and simulate the process of cooperate of ant in nature. This paper researched on the basic theory and analyzed the optimized method. The traditional algorithms have the problems of early converged or stopped, this paper improved algorithm and use to solve the vehicle scheduling. |
