The Research Of Region Logistics System And Hub-and-spoke Network

The level of logistics operation is a main indicator of economy development.Improvement of logistics system not only contributes to the competitive power of the whole nation.but also means reformation to the traditional ways of micro economy.Along with the development of area economy, the relationship between logistics and area economy has built up continually.This relationship is of different performance in different areas and different stages of economy progress.Therefore,it seems urgent and necessary to systematically analyze the framework and functions of the area logistics system,to demonstrate the inherent reciprocity and synergism patterns between the area logistics system and the area economy.The beginning of this study is to introduce the development of region logistics system and hub-and-spoke network. The designing and programming of region logistics system are talked about in this dissertation. Also the large-scale systems analysis and economical analysis of region logistics system have been done. Finally, we did the study of hub-and spoke network, model and algorithm. The main contents of this dissertation are as follows:First of all, concepts are reviewed that are related to logistics and region logistics. The character of region logistics system has been put forward. It is introduced that the actuality of the research of the theory of logistics in both china and other countries. Finally,we talked about the development process of hub-and-spoke network and its research all over the world.In addition, this article studies the designing and programming of region logistics system and analyzing the large-scale systems analysis of region logistics system. We introduce the concept, character and structure relating to the region logistics system and study the problem about the programming of region logistics. The region logistics system including hub is analyzed. This article analyzes the large-scale systems of region logistics system form four aspects, including collaboration, coordination, competition and security.Also, the effect between region logistics system and region economy system and the demand theory have been studied in this article. We analyze the influence between region logistics system and region economy system. The demand theory is studied and we introduce the concept and principle of region logistics demand analysis. The character and influence actors are pointed out and a kind of combination forecast. Finally, the hub-and-spoke network was studied in this dissertation. We introduce the concept and forming principles of the hub-and-spoke network, analyze the economy of the hub-and-spoke network and provide several kind models for the hub-and-spoke network. We shortly introduce the concept of combination optimization and computation complex and some classical heuristics. The geometry rounding algorithm is adapted into Chinese civil Aeronautic network. And, a kind of effective heuristic based on GA for solving the uncapacitated hub—and—spoke median problem with fixed fee.
