Abstract
Purpose
The purpose of this paper is to study a geometric process (GP) maintenance model and policy for a repairable system.
Design/methodology/approach
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.
Findings
For a deteriorating system, an optimal replacement policy is determined analytically, and the monotonicity properties of the optimal replacement policy are then studied.
Originality/value
For an improving system, the paper shows that the optimal replacement policy is the ∞ policy, i.e., the policy without replacement.
