Research On Logistics Integration And Transportation Coordination In Industrial Cluster

Industrial cluster is the distinct and extensive economic phenomena, and it is the approach that one country or region to obtain competitive advantage. There are many natural resources and products which need coordinated logistics service provided by different logistics enterprises in industrial cluster. The efficiency and cost of logistics system determine the market size and competition of industrial clusters to a large extent. Many logistics service providers in industrial cluster region in China are small and medium-sized logistics enterprises, and they hindered the further development of industrial clusters to some extent. The traditional logistics operation mode must be improved or changed because of dynamic development of industrial clusters, the increasing logistics demands and gradually expanding range of logistics activities.From the macro point, the traditional planning system of departmental segmentation and regional blockade stunt the growth of logistics enterprises in China. It is essential for us to build more efficient operation mode of logistics integration and relevant policies to eliminate interest conflicts between different logistics departments, cut down logistics cost, enhance logistics operation efficiency and effect, reduce the cost of supply chain, and strengthen the core competitiveness of the supply chain and enterprise competitive advantage.From the microscopic point, transportation costs occupy the vast majority of logistics cost,cutting down transportation costs can enhance the logistics enterprise competition. But the most of logistics enterprises use vehicle uncoordinated strategy today, in which each vehicle serves its customers independently, and there is no coordination between any two vehicles. If the traffic information or customer demands are uncertain, vehicle uncoordinated strategy will result in much wastage of vehicle capacity on the way. Serving under the vehicle coordinated strategy, vehicle capacity will be used more fully on the way, the vehicle loading cost and uninstalling cost are decreased, and total traffic distance is less, such that the cost is decreased while the service quality is improved. So it is significance to design more efficient vehicle coordinated strategy for coordinated logistics transportation to optimize vehicle routing.For these reasons, logistics integration and transportation coordinated strategy in industrial cluster region is considered from the following aspects in this paper. We want to integrate different logistics resources to achieve the overall optimization and reduce logistics costs.(1) We design the (f,θ, D) dynamic relative standard for logistics defination. We can define the component of logistics industry by the proposed standard, thus we rationally judge the logistics business, arrange reasonable logistics facilities in the light of the logistics operation need in fact.(2) We discuss the operation mode and strategy of logistics integration to integrate different logistics resources in different logistics enterprises based on above research. The aim is to remove the shackle of traditional planning system, improve logistics efficiency and reduce logistics cost by business cooperation between different functional departments or logistics enterprises.(3) The logistics transportation coordinated strategy and optimization in industrial cluster region is discussed in this paper. We present several new vehicle coordinated strategies for small scale logistics transportation problem, which include two vehicle-paired strategy named LPBZS, three vehicle-paired strategy named TVFDW and TVSD, and four vehicle-paired strategy named FVFD and FVSD based on the past vehicle coordinated strategies. We analyze and test proposed strategies, the results show that these proposed strategies effectively make use of vehicle capacity on the way, decrease vehicle loading cost because of service failure and uninstalling cost due to overplus, shorten distance effectively, and cut down logistics transportation cost.(4) We put forward vehicle coordinated strategies for large scale logistics transportation problem based on above researches. We design zoning approaches for large scale VRPFD, which include fuzzy clustering zoning approach based on the attributes of customer demands and improved base heuristics zoning approach. And we develop partial vehicle coordinated strategy and entire vehicle coordinated strategy based on the proposed zoning approaches, and present the best coordination subarea computing approach. We test these proposed approaches, the results show that the rationality of zoning approach has great influence on the optimizing effect, and entire vehicle coordinated strategy is better than partial vehicle coordinated strategy because entire vehicle coordinated strategy can make the best of vehicle capacity in the service process, cut down logistics cost, and enhance service quality.(5) Finally we provide the algorithms for solving VRPFD based on different scale vehicle coordinated strategy. We design hybrid tabu algorithm,hybrid gene algorithm and hybrid ant colony algorithm based on different scale vehicle coordinated strategies. And we use different scale VRPFD test instances to test these proposed algorithms. The results show that these proposed algorithms are rational and effective. It is significance for the logistics enterprises to cut down logistics transportation cost, vehicle loading cost and uninstalling cost.
