Abstract


With the development of e-commerce, the importance of modern logistics in e-commerce and more attention. Modern logistics is an integral part of e-commerce is an important guarantee to realize e-commerce, e-commerce process is complete lack of modern logistics mode; e-commerce innovation the connotation of logistics, and given the logistics information technology, automation, networking and flexible features. Modern logistics processes, the requirements of the storage areas are increasingly tend to weaken, and distribution to become the most important part of direct services for users. Distribution of the core part of the set of goods delivery vehicles, cargo equipped and delivery process, and vehicle delivery route rationalization, for the entire logistics and transport speed, cost-effective impact is crucial. In this context, the paper first start to explore the relationship between e-commerce and modern logistics, logistics in e-commerce environment mode and features for logistics vehicle scheduling problem modeling application intelligence to seek the optimal solution, have been satisfied effect. The main contents are as follows: the first outlines the connotation of e-commerce and logistics, and discuss the characteristics of the logistics and e-commerce environment, the impact of logistics. 2, analysis of the logistics characteristics and mode of e-commerce environment, are discussed in detail based on the logistics of distribution centers and distribution mode and is given based on the distribution center logistics programs and distribution processes. The structural elements of logistics vehicle scheduling problem on the basis of the system analysis, the establishment of a mathematical model of the single distribution center logistics vehicle scheduling problem. Logistics vehicle scheduling optimization problem is NP-hard problem, while the genetic algorithm search space such problems, since the characteristics of strong adaptability and robustness, so choose the genetic algorithm. 4, for the multi-distribution center logistics distribution vehicle routing problem model design based on genetic algorithm and tabu search hybrid algorithm, experimental simulation to obtain good results. And discussed on the basis of vehicle scheduling problem with time constraints and under full load. 5, the design of the logistics management information systems, business processes and functional structure, business processes and algorithms package of logistics delivery vehicle scheduling subsystem was introduced, and logistics management information system development environment, software architecture to achieve technology to elaborate.
