Technical note: The improvement of the performance of the emergency department: Application of simulation model and multiple criteria decision method

Emergency department has become a useful way to the access to hospital and it is a subject of study for many researchers. The research developed in this paper aims to improve the performance of the emergency department(ED) of Sfax Hospital. Simulation results showed that to manage to increase the number of treated patients and thus to decrease the patient cycle time, it is important to add a specialist phy- sician or a formed general physician. To choose what physician the managers do add, the researchers used the fuzzy PROMETHEE method .
