Contributions of Petri Nets to the Reliability and Availability of an Electrical Power System in a Big European Hospital - A Case Study

The energy power supply infrastructure of a hospital, to function correctly, needs be well maintained ensure its reliability and, by consequence, the maximum integrated availability. In this paper, authors propose use Petri Nets help improvement electric system reliability, having as case study big European Hospital. purpose research is identify and analyse potential failures suggest solutions improve operations maintenance maximise availability those assets through possible objective answers. It was necessary develop diagnosis planning methodology assess several components system. dynamic modelling based on block diagram transposed representation Nets. analysis simulation discrete events system, visualisation process functioning communications inside, made. Additionally, they were referred other approaches, like Fuzzy Stochastic Nets, future balance about application in situation analysed paper
