摘　　要：在随机中断环境下建立了由两个不可靠供应商和一个零售商组成的双源供应链的随机报童模型.就无约束和预算费用约束两种情形,给出了零售商的最优订购策略,进而分析了随机中断时刻对最优订购数量和零售商最大期望利润的影响,证明了零售商最优订购量的存在性.最后通过数值实例分析了随机中断时刻对订购数量和最大期望利润的具体影响.This paper develops a dual‐sourcing supply chain for random newsvendor model composed of two unreliable suppliers and one retailer under random disruption environment . On unconstrained and budget cost constraints both cases , the optimal ordering strategy of the retailer is given , and the effect of disruption time to the optimal ordering quantity and the maximal expection of the retailer are analysed , and the existence of retailer’s optimal ordering quantity is proved . Finally , the specific effect of disruption time to ordering quantity and the maximal expection profit is explained through the numerical example .
