【报告摘要】

We consider the optimal sourcing problem when the available suppliers are subject to ambiguously correlated supply risks. The problem is motivated by the increasing severity of supply risks and difficulties on evaluating common sources of vulnerability in the upstream supply chain as reported by many surveys of goods-producing firms. In contrast to the majority of existing research, we propose a distributionally robust model that constitutes a promising approach for developing sourcing strategies without requiring an accurate estimate on the underlying correlation. We provide analytical results regarding the form of the worst-case supply distribution that decision-makers may find appealing, especially when exact correlation information is unavailable, due to the severe consequences associated with supply chain risks. Moreover, we show how our distributionally robust model may be used to offer guidance on exerting additional efforts aimed at better understanding the prevailing correlation structure.
