Optimal procurement strategies from suppliers with random yield and all-or-nothing risks
Supply uncertainty has been elevated to a strategic level concern in driving supply chain success. This paper considers that a firm faces a deterministic demand and procures from two unreliable suppliers: one is subject to a random disruption and might deliver all or nothing of the firm’s order, while the other one exposes to a random yield risk for the firm’s order. We explore the models of no recourse and ordering with recourse, and derive optimal solutions for each model. We provide the conditions under which single or dual sourcing strategy should be used. We also compare the decisions and profits among different models through computational experiments and find that it is more beneficial to order from the relatively expensive supplier as a backup source.
