Abstract

By using the traffic distribution algorithm of the extended shortest OD path first and damping coefficient which based on the OD data of coal logistics and the transport network structure in Xinzhou Shanxi, the location model and application of regional coal logistics key node was established. According to the traffic flow of the coal logistics network, the location, size and numbers of the coal logistics network hubs was determined. Therefore, the optimum scheme of the key node and channel layout could be designed. Through the comparison among the three schemes, the optimal solution was selected.
