China’s Electricity-Coal Supply Chain Risk Research Based On Entropy Modified G1 Method

In the development of national economy, coal is one of the important strategic energy. And with the rapid development of energy-intensive industries, since the economy structure in China is based on the heavy industries, the demand for coal in related industries is growing rapidly. However our power generation is mainly by thermal power, so it is of upmost important to guarantee the smooth operation of the coal supply chain for the demand of generation. For the distribution of resources and consumption is imbalanced, resulting transportation pattern of coal from north to south and west to east. In order to ensure the coal smoothly transported from stored areas to consumption areas, ensure the electricity-coal supply, ensure the state power unobstructed, we must analyze the whole power coal supply chain system thoroughly. On this background, this article focuses on the risk of China’s electricity-coal supply chains and has significant theoretical and practical values.Electricity-coal supply chain is a large complicated system, including the upstream of coal supplier, middle stream of logistics service providers and downstream of coal-fired power stations. Because of the long length and large number of links, it’s quite difficult to do supply chain risk assessment and management. On the basis of defining and analyzing the supply chain of China’s electricity-coal, synthetically using Delphi method, decomposition method, risk questionnaire, this paper identifies and analyzes the risk of electricity-coal supply chains. At the same time, considering the scientific, comprehensive principle and index data availability of factors, this paper establishes the index system of China’s electricity-coal supply chain risk assessment using quantitative and qualitative methods. On this basis, this paper widely collects data, and innovatively introduced the entropy model modified G1 to assess the risk of coal supply chain, and proposes strategies and suggestions to improve China’s electricity-coal supply chain.
