Continuous and Discrete Age-Replacement Policies
Journal of the Operational Research Society, 1985For a two parameter cost model \((c_ 1=\cos t\) of replacement at failure, \(c_ 2=\cos t\) of scheduled replacement), cost-minimizing replacement policies \((T^*,N^*)\) are derived, where a unit is replaced preventively before failure at time \(T^*\) of age or at number \(N^*\) of uses.

Random Age Replacement Policies
2014It is well known in reliability theory: (1) When the failure time is exponential, an operating unit should be replaced only at failure and (2) an optimum age replacement is nonrandom [1, p. 86].
