28.1 Introduction

In maintenance policy, geometric process (GP) repairable models for single-component systems and multi-component repairable systems have drawn a great deal of attention since they were proposed by Lam (1988). A GP repairable model seems more reasonable for a deteriorating repairable system. Lam (1988) studied ...
