Abstract:This study focuses on determining the required capacity for operating rooms and polyclinical operating rooms in the ENT department of Medisch Spectrum Twente. Efficient resource allocation is crucial for optimizing healthcare utilization and patient flow. Inadequate scheduling can lead to unnecessary costs, low utilization rates, and longer completion times. The study addresses the challenge of unknown operating room capacity after reallocating treatments to polyclinical rooms. The research employs various methods, including queueing theory, "Shortest-Processing-Time," and "Longest-Processing-Time" heuristics, using historical schedules and deseasonalization of demand to identify suitable periods. The study also employs a mathematical approach, queueing theory, which requires certain assumptions and data analysis for statistical distribution determination. Key results indicate that 37.5% of treatment time in current operating rooms can be shifted to polyclinical rooms. Proper scheduling heuristics can reduce completion time by 51.63% and average makespan by 32.7%. Queueing theory suggests a potential 26.3 percentage point decrease in operating room utilization, yielding 37.3% utilization in a single polyclinical room. These findings underscore the potential benefits of reallocating treatments and optimizing scheduling. Recommendations include reserving at least 37.3% capacity of one polyclinical room for reallocated treatments, reducing operating room treatment capacity by 37.5%, and adopting proposed heuristics for improved makespan and completion time. In conclusion, optimizing resource allocation and scheduling can enhance healthcare efficiency and patient outcomes
