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

【讲座摘要】：Inspired by fast-fashion frms like Shein that gain advantage by combining multiple forms of order fexibility, 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 fexibilities reshape decisions and performance. Contrary to common belief, timing and quantity fexibilities can be strategic complements-greater cancellation fexibility, 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.
