A geometric process maintenance model and optimal policy Available to Purchase

The purpose of this paper is to study a geometric process (GP) maintenance model and policy for a repairable system.

Lam first introduced the GP and its application to maintenance model. Assume that a replacement policy N is applied by which the system will be replaced by a new, identical one following the Nth failure.

For a deteriorating system, an optimal replacement policy is determined analytically, and the monotonicity properties of the optimal replacement policy are then studied.

For an improving system, the paper shows that the optimal replacement policy is the ∞ policy, i.e., the policy without replacement.
