Modelling and design of hospital departments by timed continuous petri nets

Authors:   Mariagrazia Dotoli, Maria Pia Fanti, Agostino Marcello Mangini, Walter Ukovich


This paper proposes a model to describe in a concise and detailed way the flow of patients in a hospital starting from their arrival to the emergency medical service to the assignment of beds in the suitable department and finally the discharge. The model is based on a continuous Petri nets framework, whose fluid approximation allows us to define suitable optimization problems in order to plan the system capacity, e.g., determining the medical and nursing staff dimension and the number of beds. A case study and a simulation and optimization analysis show the efficiency of the model.
