Data-Driven Distributionally Robust Optimization for Elective Operating Room Allocation Under Moment-Based Ambiguity Sets: Exact Reformulations and a Column Generation Approach

Allocating elective patients to operating rooms (ORs) under uncertain surgery durations and limited historical data requires balancing, opening costs against overtime risk. We develop a data-driven distributionally robust optimization model (DDRO) that jointly determines OR openi...
