ABSTRACT: The quest to increase the
performance of production systems that have become complex leads to the
transfer to the maintenance function of the responsibility of guaranteeing the
availability of such systems. Also, we will never stop saying that maintenance
must integrate into all of the company’s initiatives, to affirm its role, which
is to ensure greater availability and sustainability of the means of
production. The objective of this paper is to evaluate the reliability and
availability of a system without knowing the distribution law of the operating
times. Among the methods for evaluating dependability criteria (Fault Trees,
Petri Nets, etc.), we are interested in queues that have the advantage of
taking into account functional dependencies, thus allowing a quantified
optimization of maintenance. Indeed, queues make it possible to model parallel
or sequential processes, implementing operations taking place at the same time
or one after the other, meeting the needs of modeling production systems. The
main result of this paper is the study of the influence of availability on the
reliability of a multi-state production system.
