On the Almost Threshold Policy for Multisourcing Under Uncertain Supplies In “On the Almost Threshold Policy for Multisourcing Under Uncertain Supplies,” Federgruen, Feng, and Shanthikumar examine optimal multisourcing strategies in the presence of supply uncertainty. The authors develop a general framework based on the concept of stochastic midpoint linearity and demonstrate that a simple almost threshold policy is optimal under broad and realistic conditions. Their findings provide both theoretical insights and practical guidance for designing resilient and data-driven multisourcing systems.
