摘　　要：流感疫苗与国民健康息息相关,但产出随机且需求不确定。为尽量做到供需平衡,研究双重不确定背景下流感疫苗供应链的契约协调问题。综合考虑流感疫苗作为自费疫苗的季节性特征和社会属性,在引入疫苗销毁成本和负外部社会成本基础上,以期望收益最大化为目标建立供应链决策模型。以集中决策模式下的系统收益和最优计划产量为基准,证明分散决策下的批发价契约无法有效协调双重不确定下的供应链,提出既能有效协调供应链又能使供应链成员收益得到帕累托改进的混合风险共担契约。通过算例验证了该契约的合理性。Influenza vaccines are vital to nation's health,but their manufacturers are subject to random yield and market demand is assumed to be uncertain.To preferably balance the supply and demand,this paper analytically addresses the contract coordination of influenza vaccines supply chain(SC)under dual uncertainties.Comprehensively considering the seasonal characteristics and social attribute of influenza vaccines at their own expense,a SC decision model was designed aimed at the maximization of expected revenue,on the basis of vaccine destruction and negative external social costs.Based on the optimal planned output and revenue of the investigated SC under centralized decision-making model,this paper indicated that the wholesale price contract under decentralized decision-making model could not coordinate the investigated SC,and proposed a hybrid risk sharing contract,not only to coordinate the influenza vaccines SC under dual uncertainties,but also to make expected profit of the SC actors to achieve Pareto improvement.A numerical example was presented to illustrate the rationality of the contract.
