Guemana, University of Médéa, Médéa, Algeria The automation of industrial systems increases their complexity and cost, consequently reducing their availability. Maintenance is needed to guarantee performance of production equipment. In oil and gas refineries, there is potential for numerous problems related to the reliability of complex processes, such as the turbocompressor bearing system. A probabilistic modeling approach can be used to determine optimal inspection and repair intervals for the turbocompressor bearing system, as a means of increasing the capacity
