摘要: 考察了某种产品供应链系统的一次性物流运作过程,建立了这个系统的物流能力动态规划模型。针对供应链中物流运作能力的流通量指标进行了较为深入的理论分析,探讨了使得系统成本最小化的最优物流能力及系统各阶段需配置的流通量。最优物流能力策略体现为两个关键量,即下界和上界。如果可得输入量小于下界则选择不开展物流;如果可得输入超出了下界,物流能力可以足够大但不超过上界。运用数学归纳法对优化结果进行了证明,并结合算例检验了模型的效果。

Abstract: This paper considers a one-time logistics of a product in a multi-stage supply chain system,and a dynamic planning model of logistics capability is presented for this system.The quantity as one important index of the logistics capability is analyzed theoretically,and the optimal logistics capability with the lowest system cost and flow quantity allocated at every stage are derived.The optimal logistics capability policy can be characterized by two critical numbers: the lower and the upper.If available input is less than the lower,one chooses no logistics capability; if the available input exceeds the lower,one tries to provide capability as much as possible,but nomore than the upper.The principle of mathematical induction is used to prove the conclusion,and a numerical example to test the result.

Key words: supply chain management, logistics capability, dynamic planning model, mathem atical induction, stochastic demand
