主题：A Multi-Period Commit-Then-Adjust Strategy under Convex and Piecewise-Linear Costs

摘要：Inspired by fast-fashion firms like Shein that gain advantage by combining multiple forms of order flexibility, we study a commit-then-adjust strategy in a retailer-supplier supply chain with multiple shipments. Orders can be adjusted in two directions, both in time (deferral, expedition) and in quantity (volume increases, cancellations). Using a dynamic programming model that tracks pipeline shipments, we prove that under convex and piecewise-linear adjustment costs, the optimal adjustment follows an additive base-stock policy: each adjustment region operates with the classic base-stock policy, and the optimal adjusted value equals the sum of these regional decisions. This structure clarifies how different flexibilities reshape decisions and performance. Contrary to common belief, timing and quantity flexibilities can be strategic complements—greater cancellation flexibility, for example, increases the value of expediting. Furthermore, more flexibility does not always reduce initial orders; greater ability to expedite or cancel encourages higher upfront commitments.
