报告内容提要 | |
Based on a supply chain involving a manufacturer–retailer relationship, we consider a new class of multi-shipment problem in the context of quick response (QR). Facing long production lead times and mass product varieties, the retailer places an order ahead of the season and the manufacturer delivers the order in multiple shipments. However, different from the classical multi-shipment model, we consider a common industry practice where the retailer dynamically adjusts consecutive shipments’ delivery quantities and/or times. In this paper, this Business-to-Business QR practice is termed as Consecutive Shipments Flexibility (CSF). We model two types of CSF–one with variable shipping quantities and one with variable shipping times, and formulate the multi-shipment problem with CSF as a dynamic program. In both centralized and decentralized systems, we study the optimal shipping decisions and devise incentive contracts that can achieve channel coordination. Interestingly, the coordinating conditions of the system with CSF cover all the coordinating conditions of the classical multi-shipment system. Furthermore, we find that CSF reduces the first few shipments’ quantities while increasing the total order quantity. A key enabler to achieve this result is that the cost-to-go function is proved to be separable and convex in shipping quantities. Our results underscore the importance of CSF and provide a handy tool for optimally computing the shipping quantities and/or times in the multi-shipment problems with CSF. | |
