Computing limiting average availability of a repairable system through discretization

Debolina Chatterjee, Jyotirmoy Sarkar

Abstract: Highlights•We study a one-unit system with several repair facilities and spare units.•We calculate limiting average availability for any life- and repair distributions.•We propose a discretization approach requiring only periodic inspections.•We use a simple computation technique involving state transition probabilities.•Availability increases with either more spare units or more repair facilities.
