摘　　要：本文研究了一个价格低但提前期长的海外供应商和一个价格高但提前期短的本地供应商同时向一个装配企业供货的双源采购问题。假设装配企业销售市场需求满足正态分布的情况下,提出了平滑采购策略,即当期采购量与上期采购量和当期市场需求量相关,以装配企业期望平均成本最低为目标,研究了装配企业摆放空间没有限制条件下双源采购量与库存的性质。然后在装配企业初始摆放空间有限,而将库存外包给第三方物流公司管理的情况下,研究了使装配企业期望平均成本最低的平滑采购系数和最优初始摆放空间。最后采用算例分析验证和求解了以上结论。研究丰富了平滑采购策略在双源采购问题中应用的相关研究,为装配企业进行国际双源采购提供了有利的参考。This paper studies the dual-source procurement problem that an assembler procures goods from one overseas supplier with low price but long lead-time and one local supplier with high price but short lead-time.We assume,the demand is normal distribution,a smoothing order strategy is proposed.With this order strategy,the new purchasing quantity is determined using the smoothing technique,i.e.,the new purchasing quantity equals to the weighted value of the last period purchasing quantity and the current market demand.We establish optimization models for two situations,one considers warehouse space constraint and another one does not.Then,the optimal smoothing purchasing coefficient and the optimal storage space are obtained.In the last,numerical examples are conducted.
