演讲题目：Push vs. Pull: Choosing the Right Strategy for Inventory and Speed Tradeoff
摘 要: This paper considers the design and control of a two-stage system that supplies a family of products. The key design issue is the choice of a supply chain integration strategy that enables the firm to offer customers efficient delivery services profitably. We construct a decision model for the optimal lead time and stock level of the semifinished base product that will minimize the total operational cost. We find that under some mild conditions, the optimal policy only depends on the utilization at the upstream stage regardless of the downstream stage. We find that the upstream variability has a more significant impact on the downstream variability in terms of the choice of the optimal policy, the corresponding inventory, and lead time. Further, the guaranteed/constant downstream processing time does not always benefit the supply chain performance.
