... a stochastically determined work period, resulting in temporary downtime that does not constitute a failure. An integrated modeling framework based on a semi-Markov process is proposed to evaluate the joint impact of these factors on key reliability and cost metrics, thereby supporting informed maintenance...

... The proposed system was developed using the universal concepts of a semi-Markov process, quality space and a multi-objective analysis. The maintenance and operation processes of a machine were modelled in the form of a semi-Markov process, the quality space was used to exclude the operation and maintenance...
