摘　　要：考虑一个由单供应商和单制造商组成的二级供应链,在不确定市场需求情形下考虑产品召回,站在制造商角度研究供应链线性保险合约下的最优订货决策以及最优线性保险合约决策。研究表明,最优的订货决策与产品召回概率以及线性保险系数相关,存在唯一的最优订货量来最大化制造商的利润。对于密度函数倒数的导数较大的一般需求分布函数,最优的线性保险系数与线性保险合约的固定费用以及产品召回概率有关。当产品召回概率和线性保险合约的固定费用均较小时或者产品召回概率较大但线性保险合约的固定费用适中时,制造商通过选择线性保险合约可以改善自己的利润。With globalization and the prevalence of outsourcing,global sourcing has been widely adopted by more and more companies.While on one hand,this has brought cost savings to enterprises,on the other hand,it has given rise to serious product recall risks.At present,product recall risks in many industries have created a significant impact on supply chain performance,especially in the food and pharmaceutical industries,under the condition of uncertain demand.In the case of uncertain market demand,traditional literature studies show that risk-sharing contracts can improve supply chain performance.As a risk-sharing contract,insurance contracts have been widely used for risk management.The purpose of this paper is to explore whether supply chain insurance contracts can improve supply chain performance and manufacturer profit in a secondary supply chain with product recalls and uncertain market demand.This paper,from the perspective of manufacturers,uses game theory and nonlinear optimization theory to study the optimal order decision and the optimal linear insurance contract decision under the linear supply chain insurance contract.Studies have shown that the optimal ordering strategy is related to product recall probability and a linear insurance factor.Without considering the supplier's profit constraints,when the linear insurance rate is small,the manufacturer's optimal order quantity is positive infinity,and when the linear insurance rate and product recall probability are both large,the manufacturer's optimal order quantity is nil;in other cases,there is but a unique optimal order quantity(analytical solution)that will maximize the manufacturer's profit.In comparison to traditional wholesale contracts,linear insurance contracts can increase the optimal order quantity of manufacturers.Under the optimal ordering strategy,the study finds that the manufacturer's optimal profit function is a concave function of the linear insurance coefficient,in a broad sense,but the supplier's profit function is only a concave function
