Abstract: Abstract Petri nets are used to create the maintenance model, corresponding to a mathematical and graphical tool suitable to model dynamic systems. The maintenance model developed can be considered a complete life cycle model. In addition to integrating the stochastic assessment of the degradation condition of the building components, the inspection and maintenance processes of the building components is also included. The degradation process is composed of a discrete scale of five degradation conditions, from A (no visible degradation) to E (generalized degradation). Furthermore, it is assumed that the degradation condition of the building components is not known over time and is determined only when the inspection is carried out. It is considered that inspections are frequent, with the time intervals being pre-defined by the owner/manager of the building. Regarding maintenance activities, it is assumed that an efficient maintenance program is composed of maintenance activities that allow reducing the degradation of the building component and increasing its service life, including replacement activities corresponding to the building component’s end-of-life to restore to the condition “as-good-as-new”.
