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