Análise de desempenho do SAMU de Ouro Preto e Mariana através de modelos de simulação

The Emergency Medical System of Ouro Preto and Mariana operates together, continuously, 24 hours a day, seven days a week, using four ambulances fixed located in three bases scattered throughout the region. Given the degree of uncertainty of the system coupled to the number of parameters capable of interfering in its efficiency, it is interesting to determine and evaluate indicators to make a diagnosis of the complete situation of the emergency system in the region in line with the service quality analysis. In this sense, this work proposes discrete event simulation models that, after validation, were able to analyze (1) the location of ambulance bases in centralized and decentralized configurations, (2) the behavior of the system in meeting the estimated real demand, (3) the performance of the system after the removal of an ambulance using two ambulance dispatch policies, and (4) the changes in system demand throughout the day. The results were able to point out the positive and negative technical features of each scenario, as well as any possible bottlenecks in the system.
