China＇s natural gas industrial chain is entering a stage of rapid growth. In order to guarantee healthy development of the natural gas industrial chain, it is urgent to establish a risk alert system, which is based on a risk assessment index system. First of all, the risks of the natural gas industrial chain are defined in the paper; then the risk factors are analyzed according to the present status of the natural gas industrial chain, and five categories of risk factors are summarized： resource risk, transport risk, marketing risk, risk of unbalanced chain links, and environment risk. The paper presents the principles of the risk assessment index system. The natural gas industrial chain risk assessment index system is established with four levels and forty-six risk indices.展开更多
在实际生产中,天然气供应链系统的构建需要考虑诸多影响因素,但大多数研究考虑的运输方式较为单一,且无法有效解决城市需求量的季度性波动、输送方案与结构布局同时优化等问题。综合考虑输送模式、体积、运输设备、供需能力及站场建设...在实际生产中,天然气供应链系统的构建需要考虑诸多影响因素,但大多数研究考虑的运输方式较为单一,且无法有效解决城市需求量的季度性波动、输送方案与结构布局同时优化等问题。综合考虑输送模式、体积、运输设备、供需能力及站场建设方案等约束,以天然气供应链平均日运行费用最小为目标函数,建立了混合整数线性规划模型(Mixed Integer Linear Programming,MILP)。以某天然气供应链系统年需求任务为例,在满足城市天然气需求量的同时使系统的建设及运行总费用达到最小,求解得到了最优的建设方案、购买方案、运输方案、储气方案及处理厂操作方案,并验证了该模型的准确性,可为天然气供应链系统建设提供指导。(图3,表12,参27)展开更多
