Research On The Optimization Of Logistics Distribution Area And Distribution Route

Logistics is the effect of one of contemporary science. Logistics system there is a important link, namely the logistics distribution system. The system is mainly concerned about two issues:the determination of reasonable freight transportation and distribution area and distribution process of distribution route choice.In the division of regional distribution, this paper puts forward in humans in production of a "field" phenomenon, using the logistics field to analyze problems such as logistics density. The scope of meshing sure logistics density. After the division of its attunements processing, and value of its corresponding grid logistics density.For bitmap to adjacent points minimum connection degrees search, will point value and logistics density compared minimum value, if the threshold inside, criterion that point can become the a section, if less than the lower threshold, the circulation search, will search to point to join the current category, and ensure the merge points number no more than constraint cap on the number. And the point is missing with processing.The statistical distribution model of period of time, the cycle on freight cargo traffic between zones statistics, for different degrees of freight volume being colored, eventually, a unit of time travel, the startingα-γarea-the OD traffic volume purpose distribution.The choice of routes for distribution, combined with the graph theory related algorithm, based on the computer software, in turn, cost, time to consider journey and so on various factors, in different constraints, and gives the distribution of the route optimization plan freight. Comprehensive consideration of the save money, time saving, and convenient and other factors, given in three feasible scheme (respectively the journey, cost, schedule that the optimal distribution alignment) later, using Analytic Hierarchy Process (AHP) method AHP (Analytic Hierarchy Process), establish pass class time structure model of the structure of the judgment matrix and the level sort and consistency inspection, finally obtained in the final of the weight of the three executives, for we need of optimization scheme provides basis for decision-making.The conclusion is:wait density grid attunements zoning method can search reflects different period the absolute dynamic logistics and relative stability features, to the city logistics distribution division is of high reference value. Will di jester pull algorithm combining with cruise Carl algorithm, and in different under the restriction of the shortest path selection method, and have strong adaptability and can be high computing efficiency. While this research method in other fields of similar problems with extensibility.
