摘 要: 一个供应链包括从原材料的采购到顾客获得产品直接和间接的所有过程.文章考虑具有多个供应商和制造商面对成品产品的随机需求的供应链网络问题.一个供应链的循环时间是指从原材料的采购、成品产品的制造到顾客拿到产品全过程需要的总时间.提出一类具有多个供应商的供应链网络数学模型和相应的Lagrangian算法,获得了减少供应链网络的循环时间和潜在费用的方法. Supply chain consists of all stages involved,directly or indirectly,in fulfilling a customer request. In this paper we consider a supply network consisting of a manufacturing company which faces random demand for a finished product with multiple suppliers.The cycle time of a supply chain equals the total time required to complete the total process from raw materials to the delivery of finished product to the customers. We develop a mathematical model and a Lagrangian algorithm that obtain a reduction method...
