Attributes of urban logistics nodes and their mathematical description
This paper aimed to analyze attributes of urban logistics nodes and proposed methods of mathematical description of these attributes. In order to research attributes of urban logistics nodes and edges, the concepts of the logistics nodes of generation, the logistics nodes of attraction and the logistics nodes were proposed, the urban logistics nodes topology map in a general condition was established, the basic types of urban logistics nodes were stated, the classification method of urban logistics nodes was putted forward. By graph theory and complex network theory, the attributes of urban logistics nodes included clustering coefficient, degree, stock, throughput capacity. The attributes of edges were connectivity, throughput capacity. The formula of computation with regard to the characteristics of nodes and edges were given. The relations of stock and throughput capacity of nodes, throughput capacity of nodes and edges were discussed in which some valuable conclusions were accessed. The applicability of the proposed formula was illustrated by a sample.
