Bayesian non-parametric specification of bathtub shaped hazard rate functions
Richard Arnold, Stefanka Chukova, Yu Hayakawa
Hazard rate functions of natural and manufactured systems often show a bathtub shaped failure rate. A high early rate of failures is followed by an extended period of useful workin…

Warranty Cost Analysis with an Alternating Geometric Process
Richard Arnold, Stefanka Chukova, Yu Hayakawa +1
In this study we model the warranty claims process and evaluate the warranty servicing costs under non-renewing and renewing free repair warranties. We assume that the repair time…

Modeling Repairs of Systems with a Bathtub-Shaped Failure Rate Function
Sima Varnosafaderani, Stefanka Chukova
Most of the reliability literature on modeling the effect of repairs on systems assumes the failure rate functions are monotonically increasing. For systems with non-monotonic fail…
