Study On The Layout Optimization Theory And Method Of Urban Logistics Corridor System

Along with the development of the modern logistics continuously, the urban logistics conveyance need is increasingly outstanding ,which cause freight transportation vehicle to increase consumedly, and turn worse the urban transportation to hustle and pollution of the environment. The efficiently urban logistics corridor system is a key which solves the city transportation hustle, satisfies the city logistics infrastructure construction, and promotes the urban logistics efficiency. Therefore, the research on the layout optimization theory and method of urban logistics corridor system, which can put forward kinds of method and model, is theoretically and practically meaningful .The main contents of this paper are stated as follows:(1) The paper particular analyses the meaning and characteristic of the logistics corridor. It defines the urban logistics corridor; and gives the main constitute factor of ULCS. According to the analysis on the system function and configuration, some traffic management suggestions are presented.(2) The paper analyses the layout theory of the ULCS. The space form structure and the space ability structure are researched based on the principle of the ULCS layout. Meanwhile the adaptable evaluation index system is established, as well as the applied comprehensive evaluation model and method of ULCS layout.(3) The thinking and method of the ULCS layout has been proposed. As to design method which can meet the principal flow direction of the logistics needs ,The author emphasize analyses the location design and line choose of ULCS's main frame. And the consideration on the layout of support network and the important logistics nodes connection, which is valuable for the macro plan and the preliminary choose of urban logistics corridor.(4) The paper builds up the optimization models of the ULCS layout. Based on the relationship of logistics corridor layout and logistics capacity, the paper constructs simply optimization models and algorithm on layout of logistics corridor; The objective of the two-double programming model is to minimize the generalized logistics' total cost and maximize the logistics capability, which is the analysis tool to optimizing the layout of urban logistics corridor system.In conclusion, the paper makes some progress in the function analyse and the disposition system of corridor, the space form and logistics capacity,the layout design and the optimum model building, as well as the adaptability appraisal of the urban logistics corridor. The research results have significant leading meaning to corridor layout in practical operations.
