Simulation of trends of maintenance policies. A case study in a Hospital

This paper proposes a simulation model constructed by means of Matlab software that enables the visualization of trends of maintenance policies (Corrective, Preventive and Condition Monitoring) taking into account specific initial conditions and different levels of efficiency in the set up of a Condition Monitoring Programme. Once a maintenance policy has been set-up, different factors must be controlled to enable deficiencies to be detected early; the detection and diagnosis of these irregularities is the reason behind the development of the simulation model of trends of maintenance policies. The model has been applied to a Hospital where maintenance efficiency not only has an influence on the machines but also on people, by directly influencing the quality of the patients' welfare service.
