A modelling and simulation framework for intelligent control of emergency units in the case of major crisis

A modelling and simulation framework for the performance evaluation of emergency units and intelligent control in the case of major crisis is proposed in this paper. Taking into account new challenges related to the optimization of the patient care pathway in the emergency unit in the context of major crises, we propose a flexible tool that can be used by health-care practitioners as a decision aid in various situations under the shape of a digital twin of the emergency unit. The modelling framework is based a modular model with specific representation of care pathways and resources activities. Various arrival processes are modelled in order to comply with the periodic variations observed in data history as well as exceptional massive arrivals that may be related to major crisis. A practical experiment is provided in order to determine the best available leverages to optimize the operations of the system.
