In this chapter we present a number of approaches to operating theatre planning and scheduling. We organize these approaches hierarchically which serves to illustrate the breadth of problems confronted by researchers. At each hierarchical planning level we describe common problems, solution approaches and results from studies at partner hospitals.In this chapter we address operating theatre planning problems on three hierarchical managerial levels: strategic, tactical and offline operational planning, as introduced in Section 5.2.The remainder of this chapter addresses recent work in each of these three levels of control. Section 5.2 outlines the planning and control functions on the aforementioned hierarchical levels in an operating theatre department. Section 5.3 addresses the strategic problem of determining the target utilization of an operating theatre department. Section 5.4 addresses the strategic problem of determining the number of surgical teams required during the night to deal with emergency cases. Section 5.5 addresses the strategic decision whether to use emergency operating theatres. Section 5.6 addresses the tactical problem of determining a master surgery schedule (a day-to-day allocation of operating theatres to surgical specialties) that levels the workload in subsequent departments (wards). Section 5.7 addresses the offline operational problem of scheduling elective surgeries with stochastic durations, and sequencing them in order to reduce access time of emergency surgeries. We will use a wide array of OR techniques, including discrete event and Monte Carlo simulation, statistical modeling and meta-heuristics.
