活动简介：

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. Orderscan 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 underconvex and piecewise-linear adjustment costs, the optimal adjustment follows an additive base-stock policy:cach adjustment region operates with the classic base-stock policy, and the optimal adjusted value equals thesum of these regional decisions. This structure clarifies how different flexibilities reshape decisions and perfor-mance. Contrary to common belief, timing and quantity flexibilities can be strategic complements-greatercancellation flexibility, for example, increases the value of expediting. Furthermore, more flexibility does notalways reduce initial orders; greater ability to expedite or cancel encourages higher upfront commitments.
