报告摘要

Motivated by time-varying physician productivity in emergency departments (EDs), we employ optimal control theory, namely Pontryagin’s principle, to analyze physicians' transient behavior during shifts. We find that this behavior is primarily influenced by shift-based scheduling. We use time-varying patient-per-hour (PPH) data to model the ED as a dynamic multi-server queue. Our simulations, validated with Canadian ED data, reveal that our model accurately predicts patient wait times compared to constant service rates. This highlights the importance of considering time-varying service rates for precise ED modeling. Our approach simplifies performance evaluation, aiding physician staffing optimization, resulting in significant cost savings in practice.
