忠实契约下石油装备闭环供应链对需求突发事件协调能力的实证研究

石油石化行业是中国的能耗大户,行业范围内的突发事件发生频率近年呈上升趋势,闭环供应链管理是石油装备制造业实现节能减排的重要手段。需求突发事件会给石油装备闭环供应链带来一定程度的影响。当石油装备的产品需求变化不大时,忠实契约参数可以保持不变,此时供应链具备协调性;当市场需求变化较大时,修正忠实契约参数依然可以使石油装备闭环供应链保持协调性。无论需求变化大小,石油装备经销商的市场回收价格均无需改变。

An Empirical Study of Coordination Ability of Petroleum EquipmentClosed-loop Supply Chain with Fidelity Discount Contract underDemand Disruptions

Abstract： Petroleum and petrochemical industry is the major part in China energy consumption, and closed-loop supply chainmanagement is an important thought for petroleum equipment industry, which has been committed to energy conservation and emissionreductions. In view of the frequent emergencies on an industry scale, the frequency is on the rise in recent years. The result shows thatdemand disruption can cause a certain degree of effect to petroleum equipment closed-loop supply chain; the fidelity discount contractparameters can make the petroleum equipment supply chain coordinating when little demand changed, and the supply chain canmaintain coordinating by parameters adjusting when large demand changed; no need to alter the recycling price of petroleum equipmentin any case.
