Abstract: We consider the case of a mono-production of a small quantity of complex (and expensive) systems, where we have to determine, at the moment when the global system is produced, the quantity of spares we want to produce for life-time maintenance purposes. The present difficulty comes from the fact that we assume that the steady state mean up time is not known precisely but is considered as uniformly distributed on a time interval [a, b].

Keywords: uncertainties; MUTs; mean up times; uniform distribution; reliability; maintenance spares; risk assessment; complex systems; mono-production; lifetime quantities.
