Abstract Operating room (OR) allocation has multiple criteria such as OR’s opening cost, overtime cost, surgery setup cost and preferences. This paper addresses the multi-objective operating room allocation approach in order to optimize the above four criteria with uncertain surgery times. A linear programming model was proposed to optimize a linear combination of the four criteria and by using a Monte Carlo method to handle the surgery time uncertainty. The numerical results obtained with a standard LP-solver (Cplex) show that this method considerably reduces the total operation cost of ORs. It effectively reduces the average overtime and surgeries setup frequency while meets surgical preferences to a large extent.
