针对突发事件下销售价格敏感系数、回收价格敏感系数、制造成本和再制造成本同时扰动,研究了闭环供应链系统的生产(回收)策略、销售价格(回收价格)策略与协调机制,给出了不同扰动条件下生产(回收)调整策略与销售价格(回收价格)调整策略,并设计了新的回馈与惩罚契约,使得闭环供应链能够在突发事件前后都能够实现协调应对,最后通过数值实例验证了结论的正确性.研究表明:闭环供应链受突发事件的影响很大,但通过对回馈与惩罚契约的调整及其相对应的制造(回收)策略与销售价格(回收价格)策略的调整,可有效减少突发事件对闭环供应链利润的损失.
Aiming at the sensitivity of sales price, sensitivity of recovery price, manufacturing cost and remanufacturing cost under sudden event, the strategies of production (recovery), selling price (recovery price) and coordination mechanism of closed-loop supply chain system The strategy of adjustment of production (recovery) and adjustment of sales price (recovery price) under different disturbance conditions and the design of a new contract of repay and punishment make it possible for the closed-loop supply chain to co-ordinate before and after the emergency. Finally, The results show that the closed-loop supply chain is greatly affected by emergencies, but through the adjustment of the feedback and punishment contract and its corresponding manufacturing (recovery) strategy and sales price (recovery price) strategy The adjustment can effectively reduce the loss of profit in the closed-loop supply chain.
