Liuzhou Schindler Logistics Center And Distribution Optimization

With the increasing development of urban economy,the demand for distribution system is more and more urgent.Loading and transportation is a key link during logistics delivering,The rational project of cargo loading will economize the capacity of wagons,The exact planning of vehicle routing in distribution will reduce rate of empty driving,lower cost of distribution and take great effect on the customer service level.The quality of in distribution scheme has great influence to improve the operating efficiency of the whole logistics system and reduce the cost of transportation.However,by now in the practical operation,most distribution centers do them by experience.So,in order to adapt to the rapid growth of distribution,the research on how to use the capacity of wagons and vehicle routing to improve the economic benefit and social benefit what distribution center can gain is necessary.On the basis of analyzing the current situation in XunDa Logistics Center of Liu Zhou,this article discuss the distribution of the logistics center from two aspects: the direct transportation and and indirect transportation.This paper present the optimization of loading and transportation.Firstly,the research of loading,Aimed at the low efficiency of truck loading,during making the models,the paper mainly consider such factors as model of vehicle,the volume of the truck,the load of the truck,empty transport rate and so on.The loading plans were made to utilize the volume and carrying capacity by using optimization methods for different loading models.According to the characteristics of the goods transportation and the combination theory,the chapter completes the different algorithms for the mathematic models of loading of goods.Secondly,this paper established a model with the Dijkstra's Algorithm under the traffic conditions to give the methods and processes to optimize the routes of transiting goods.Finally,this paper proposed models and optimizations with two optimal objections which are to solve the loading and delivery dispatching problems under vehicle capacity. The completion of thesis is good for center's service level and satisfying customer's demand.Also the thesis brings forward basic thinking way,method and step for solving loading and line optimization problem,it has directive meaning for distribution optimization.
