Abstract


With the continuous development of modern logistics, urban logistics and transport demand is becoming increasingly apparent, urban road freight vehicles greatly exacerbated urban traffic congestion and environmental pollution. Build efficient city logistics channel system is the key to solve the urban traffic congestion, urban logistics infrastructure to enhance the efficiency of urban logistics. Therefore of city logistics channel system layout optimization theory and methods to study proposed a realistic model for the development of modern logistics industry has important theoretical and practical significance. The paper mainly the following aspects: (1) carried out a detailed analysis of the meaning and characteristics of the logistics channel. Define the concept of urban logistics channel, the main elements of the system of urban logistics channel; functional orientation of the channel system of urban logistics and system configuration; logistics channel traffic management proposals. (2) In-depth analysis of the layout of the city logistics channel system theory. Premise of the basic principles of clear urban the logistics channel system layout, detailed analysis of the spatial form of urban logistics channel system structure and space logistics capability structure; the adaptive evaluation index system of urban logistics channel system layout, practical integrated evaluation models and methods. (3) The proposed the city the logistics channel system layout optimization design ideas and methods. Targeted to meet the logistics needs of the mainstream to the design methods, the focus system is the main framework of the district-bit design and line select, at the same time consider the support network of the layout as well as connecting the important logistics nodes logistics channel's layout to guide urban logistics channel macro planning channels the primaries have better guidance value. (4) establishment of a mathematical model for urban logistics channel layout optimization. Based on the analysis of the relationship between the logistics channel layout and logistics capabilities, the simple logistics channel layout optimization model; establish the to achieve generalized logistics costs to minimize and channel logistics capacity maximization as the goal of the bi-level programming model, given The algorithm of the model, provides a better analysis tool for the city to seek a reasonable logistics channel layout. Spatial form paper through the analysis and research of the above aspects, the channel functional analysis and system configuration, layout and space logistics capabilities, layout method, optimization modeling method and adaptability evaluation made some progress on the logistics channel layout has a certain significance.
