Abstract

This paper considers the reliability analysis of systems whose operation time is managed with regard to criticality of faults. Several analysis approaches are proposed for the numerical probability analysis of one such operational scenario: FOTM (flight operation time management). The equations derived for the Markov chain based method are novel and their implementation in the tool SPNP (Stochastic Petri Net Program) could help in assessing the risk reduction due to FOTM. The analysis methods are quite general and can be applied to other similar situations where system-failure risk is decreased by operation-time management
