Chapter 6

Repairable System Reliability

This chapter considers the reliability of multiple-time-use systems that are repaired when they fail. The effectiveness of repairs varies from restoring a system to a brand new state to restoring it to the reliability just before the system last failed. Several models for failure count and failure time data collected on repairable systems allow for different degrees of repair effectiveness. The models considered include renewal processes, homogeneous and nonhomogeneous Poisson processes, modulated power law processes, and a piecewise exponential model. This chapter also addresses how well these models fit the data and evaluates current reliability and other performance criteria, which characterize the reliability of repairable systems.
