Logistic Transportation Routing Optimization Research Before Production In Automobile Factory

With the development of market economy and logistics technology, physical distribution business developed rapidly. In physical distribution business, the vehicle scheduling problem affects mostly on raising service quality, reducing logistics cost and increasing economic benefits of physical distribution enterprises. In daily life and production, many problems such as mail delivery problems, bus scheduling problems, electricity dispatching problems, pipeline laying problems and computer network designing problems can all be seen as physical distribution vehicle scheduling problems. Taking physical distribution vehicle scheduling problem as its studying object, this paper has both theoretical and practical value. Logistic vehicle routing problem is combination optimization that is difficult to solve. Due to its NP characteristics, we can't get satisfying results when we use exact approaches and normal heuristic ones. On the basis of building the models of physical distribution vehicle scheduling problems, this paper studies the methods of partitioned logistics delivery and operations research (Hamilton) to solve them. This study focuses on the optimization of the transportation in physical distribution. After a review of the concepts and theories of logistics, delivery, transport etc, This study analyze the matter and researched in algorithm for reducing transport cost. The main content of the paper is as follows: 1.Based on the analysis and summarization on lots of involved references, this paper reviews the basic related concepts of transportation in physical distribution. The definitions and characteristics of items like logistics, delivery, and transportation are expounded, the difference between traditional transportation and distribution transportation are analyzed, and the measures for rationalization of distribution transportation are suggested in the paper,furthermore, we need avoid all kinds of illogical forms in traditional distribution transportation, such as returning to base or empty drive; convective transportation; circuitous transportation; repeated transportation; refluent transportation; faraway transportation; in the meaning time, five elements of logical transportation must be considered-transportation distance; transportation tache; transportation facility; transportation time; transportation expense, multifarious logical measures in...
