Abstract
Recent years, logistics, taken as "third profit resource”, has been developing rapidly. In the developed commercial society, traditional VSP algorithm have been unable to meet the requirement that Quick Response to customer demand had brought forth, then the conception of Time Window has come into being. The vehicle-scheduling problem with time window is also a NP-hard problem being more complicated than VSP.
This text has been researched to the vehicle-scheduling problem with time window on the basis of researched to logistic vehicle scheduling problem. And it has explained the basic theory of genetic algorithm.
On the VSP with time window, while the restraints of capacity and time windows are changed into object restraints, a mathematic model is established. We use technique such as maximum preserved crossover and design genetic algorithm on nature number, which can deal with soft time windows through experimental analysis, have made better result. Because this problem was studied together for group members, this text has expounded the part about fitness function and mutation operator that I finished.
