RE: NUMERICAL PROBS ON AVAILANILITY
A more realistic, but extremely more difficult availability includes the MLDT, mean logistical delay time, in the denominator. MLDT takes into account the availability of repair parts and the possibility of needing to send for repair parts from the logisitics chain or depot. A typically used MLDT is 72 hrs, which is pretty absurd, but we use it. A correctly calculated MLDT should have individual MLDT's for each replaceable component weighted by its failure rate.

...which is to say nothing of good ol' thermodynamic availability, which is "equal to the maximum reversible work, minus the work done against the surroundings" [Van Wylen & Sonntag]
If this is what you're after (though I suspect that IRstuff addressed your question), I suggest one of those problem solving workbooks on thermodynamics.
