Research on the Coal Logistics Network's Property Based on the Complex System Theory of Supply Chain

This article puts forward the practical significance of studying the complex characteristic of coal logistics network from the coal resource effective utilization and rational allocation. According to the characteristics of coal enterprises, the coal logistics network is defined as the complex network system. Based on the complex system theory of the supply chain, the coal logistics network is analysed separately from the complexity of node and structure, the small word property as well as the scale-free property and it is pointed out that the coal network has complex network structure, the small world property and the scale-free property.
