Abstract

This paper studies the design of flexible purchase contracts in supply chains under demand uncertainty and information asymmetry. In this setting, downstream buy-ers have complete information about the demand distribution, whereas suppliers can only rely on historical demand realizations and contract terms, resulting in limited knowledge of the true distribution. We first reveal the fragility of classical contract design methods in small-data regimes and illustrate typical cases where they may incur substantial losses. To address this issue, we propose a dual-source data-enhanced em-pirical distribution inference method based on inverse optimization. Building on this inference, we develop a dual-source data-driven Wasserstein distributionally robust optimization (DWDRO) framework for flexible purchase contract design. To evaluate the supplier’s worst-case profit, we design a decomposition approach that leverages set partitioning and Lagrangian duality to decouple the supplier’s pricing model from the identification of the downstream buyer’s admissible reservation bounds. Numerical results demonstrate that the proposed framework effectively narrows the gap between the empirical and true demand distributions, improving the accuracy of demand esti-mation. Under small-data conditions, it also significantly enhances the out-of-sample worst-case profit of suppliers compared with classical WDRO models. These findings suggest that the proposed method provides upstream suppliers with an effective tool to hedge against information asymmetry in contract design.
