Basic Reliability Concepts
Abstract
The basic reliability functions that can be used to model lifetime data and explain the failure patterns are the topics of discussion in this chapter. We begin with the conventional hazard rate defined as the ratio of the probability mass function to the survival function. This is followed up by an alternative hazard function introduced to overcome certain limitations of the conventional rate. Properties of both these hazard rates and their interrelationships are discussed. Then, the concept of residual life distribution and its characteristics like the mean, variance and moments are discussed. Various identities connecting the hazard rates, mean residual life function and various residual functions ...
