Due to the deficiency of logistics distribution, this paper presents a new approach to deal with VRP problems and utilizes network analysis function of GIS. Firstly, this paper specifies how to establish road network based on GIS. Secondly, this paper focuses on Vehicle Routing Problems with Time Window constraints. Finally, article based on the network analysis function of GIS, routing results on...
Distribution is an important part to connect directly to the consumer in logistics system, optimizing the distribution system, can improve the logistics cost, and make logistics scientific,so optimization of distribution system is particularly important. For the optimization of distribution system,the optimization of vehicle scheduling is a key link. First of all,this article analyzes the vehicle...
It has set up a mathematics model of VRP problem with time windows and has proposed a kind of improved immune genetic algorithm. On the basis of the standard genetic algorithm, it joins in the self-adaptation cross operator and heuristic mutation operator based on triangle show, and uses niche technique to improve the immune algorithm. The experimental result indicates that this algorithm has better...
In this paper a logistics transportation problem including routing, scheduling and loading tasks is presented. Most of the related works only involve the solution of routing and scheduling, as a combination of up to six different types of VRPs (Rich VRP), leaving away the loading task, which are not enough to define more complex real-world cases. We propose a solution methodology for transportation...
