Multi-Agent Systems in Emergency Departments: Validation Study on a ED Digital Twin
Summary
A hybrid Discrete Event Simulation (DES) and Agent-Based Model (ABM) has been developed to simulate highly configurable emergency department (ED) environments, addressing challenges in patient care and resource management. The model's expressivity was validated by matching its key performance indicators and metrics against values from existing literature, using ED sizes, patient loads, and staffing configurations derived from real-world studies. The DES-ABM simulation successfully replicated real-world ED dynamics under various interventions, comparing documented outcomes with model results. A Proof-of-Concept multi-agent system (MAS) was integrated to autonomously explore resource allocation strategies within the simulated ED, utilizing a temporal ledger of ED event records. This modular DES-ABM-MAS framework provides a robust tool for exploring optimization strategies.
Key takeaway
For healthcare administrators and operations researchers optimizing emergency department workflows, this DES-ABM-MAS framework offers a validated tool to test resource allocation strategies virtually. You can explore the impact of different staffing levels or patient loads without disrupting actual operations, potentially identifying more efficient care delivery models and improving patient outcomes.
