Fiabilité dynamique et disponibilité de production: un cas illustratif

Abstract : Production availability is a probabilistic measure of the production regularity of a system. Its estimation is usually based on the following assumption: the production level associated to each system state – either normal or degraded – is instantaneously reached when entering this state. Actually, two types of more realistic situations can be encountered: either this production level is one of the continuous variables describing the industrial process under study, or the transitions between discrete states (and consequently between production levels) are conditioned by the evolution of these continuous process variables. Dynamic reliability, a discipline in RAMS modelling dealing with hybrid discrete-continuous systems, is thus a natural way to look at production availability issues. This work illustrates the impact of a realistic modelling of the continuous process on the RAMS characteristics of a simple problem coming from the gas industry.
