摘　　要：针对制造商的柔性产能投资问题,构建了由制造商和零售商组成的双层供应链模型.通过比较分析,发现分散系统下企业的决策偏离集中系统下的最优决策.针对该问题,设计了“残值补贴+缺货惩罚”契约对该结构进行协调.结果表明,两企业都获得了更高的期望收益,供应链期望收益实现了Pareto改进,且可以通过调节契约参数实现两企业间期望收益的任意分配.另外,仅当订货量超过一定阈值时,制造商才会投资柔性产能,且柔性产能投资成本系数和生产成本系数分别会对该阈值施加正向和反向影响.Considering a manufacturer’s investment in flexible capacity,a two-stage supply chain model consisting of one manufacturer and one retailer is established.Through comparison and analysis,it is found that the optimal decisions of the firms in the decentralized system are deviated from those in the centralized system.Aiming at this problem,a contract with combination of residual subsidy and shortage penalty is designed to coordinate the structure.The results show that both firms can achieve higher expected profits,the supply chain can realizes Pareto improvement,and the expected profit of the supply chain can be arbitrarily allocated between the two firms by adjusting the contract parameters appropriately.In addition,only when the order quantity exceeds a certain threshold,will the manufacturer invest in flexible capacity,with the cost coefficients of investment and production of flexible capacity exerting positive and negative effects on the threshold,respectively.
