Study On Logistics Vehicle Scheduling Problems

Transportation comprises a significant fraction of the national economy. In the routine work, various modes of transportation all face such a common problem: how to make routes and timetables for the vehicles that passengers and goods can be transported from one place to another efficiently. These problems are generally known as vehicle routing problems (VRP) in the circles of operations research.With increasing intensification of marketing competition, step out of global integration, and speedy development of science and technology, many enterprises have been conscious that logistic is an important measure to improve the ability of market competition and exalt the ability of coral competition, Being an important approach to realize logistic rationalization, research on vehicle routing problems will help enterprise to reduce logistical cost, improve operation efficiency, and enhance customer satisfaction roundly.It is clear that the vehicle routing problem is the key problem in the optimization of transportation operations. Because vehicle routing problems bridge theory of Operations Research and practice of production, they are named as one of the most successful areas in Operations Research in the past decades.Based on many related literatures, this article summarized the research findings in Vehicle Routing Problems (VRP) both internal and external. Upon the description on VRP and analysis of the VRP Model and Algorithm, this article analyzed the factors that affect the vehicle dispatch in physical distribution and also their separate influences on the VPR Model and Algorithm. Plus the adding of the Incomplete Information System data filled arithmetic ROUSTIDA Algorithm , which replenish those absent datas of the influencing factors, offers scientific and integrated foundation to the vehicle dispatch in physical distribution. Some Countermeasures and suggestions were proposed on VPR system development at the end of this article.
