电煤供应链改进收益共享契约协调机制设计

Design of the coordination mechanism for the improvement of revenue sharing contract in the electric coal supply chain

契约是供应链机制设计的重要方式,对电煤三级供应链提出了基于修正Shapley方法的电煤供应链改进收益共享契约的协调机制,用Shapley值法确定收益共享契约中的各个节点企业的交易价格,考虑风险分担、知识共享、合作贡献等多种因素,修正各节点企业应分配的利益,利用直觉模糊原理确定各个供应链节点企业利益分享的修正系数,得出了电煤三级供应链中收益共享契约相应参数的具体取值,通过算例证实改进收益共享契约参数设计的合理性和有效性。

Contracts are an important method of supply chain mechanism design.For the three-tier supply chain of thermal coal,a coordination mechanism for improving the revenue-sharing contract of the thermal coal supply chain based on the modified shapley method is proposed.The Shapley value method was used to determine the transaction price of each node enterprise in the revenue sharing contract.Considering various factors such as risk sharing,knowledge sharing,and cooperative contribution,and revising the benefits that each node enterprise should allocate,the intuitionistic fuzzy principle was used to determine the correction coefficients of the benefit sharing of each supply chain node enterprise.The specific values of the corresponding parameters of the revenue sharing contract in the three-tier supply chain of thermal coal are obtained,and the rationality and effectiveness of the parameter design of the revenue sharing contract are improved through calculation examples.
