Optimization of scheduling decisions for outpatient procedure centers
Outpatient procedure centers (OPCs), are a fast growing trend for providing specialty healthcare procedures (surgical and non-surgical). Many procedures previously required resources only available in hospital settings; however, advances in medical care and technology have made it possible to provide these services through minimally (or non) invasive procedures that can be provided at low risk in OPCs. Management of OPCs involves many challenging decisions including how many procedure rooms to plan for a given day, how to allocate procedures to rooms, and how to control overtime cost. This talk will describe how stochastic optimization models can be used to make effective decisions that consider these competing criteria. We describe exact methods that find optimal schedules based on decomposition methods. We also discuss practical and easy-to-implement heuristics and an analysis of their worst-case and average case performance relative to optimal solutions. Finally, we present numerical results, based on a real OPC, to evaluate the performance of the exact and heuristic methods, and to draw managerial insights.
