摘要
考虑到突发事件导致市场需求和市场价格随机波动、供应链成员信息不对称。在此条件下,通过双边拍卖确定线性均衡批发价,并运用应急回购契约协调二级供应链,得到契约参数的约束条件,最后通过算例验证突发事件对整个供应链系统利润分配的影响。结果表明:需求增大的突发事件发生时,线性均衡批发价及零售商期望利润均会增加,但零售商占整个供应链系统利润的权重会降低;需求减少的突发事件发生时,线性均衡批发价及零售商期望利润均降低,但零售商占整个供应链系统利润的权重会提升。价格随机的突发事件下,对线性均衡批发价做出调整,供应链能够实现协调。此外,在满足一定约束条件下,零售商对商品估价越低,其利润占整个供应链利润的权重越大。
The unexpected events can lead to the random fluctuation of the market demand and price,and the information asymmetry of supply chain members as well.Under this condition,the linear equilibrium wholesale price was determined through two-way auction.Then,emergency repurchase contract was used to coordinate the two-level supply chain and obtain the constraints of contract parameters.Finally,an example was given to analyze the impact of emergencies on the overall profit distribution in the supply chain.The research results show that when an emergency with increasing demand occurs,the linear equilibrium wholesale price and the expected profits of retailers will increase,but the weight of the retailers'expected profits in the entire supply chain will be reduced.However,when an emergency with decreasing demand occurs,the linear equilibrium wholesale price and the expected profits of retailers will be reduced,but the weight of the retailers'expected profits in the entire supply chain will increase.In addition,under certain constraints,the lower the retailer's valuation of goods is,the higher the weight of its profits in the entire supply chain is.
