Utilizing experimental degradation data for warranty cost optimization under imperfect repair

Reliability Engineering & System Safety, 2018
Manufacturers usually want to predict the warranty cost for new products under affordable maintenance policies. With insufficient reliability information, experimental degradation tests are commonly conducted to predict the field reliability before the ...

Repairs under imperfect information

Journal of Urban Economics, 2013
Abstract We propose a theory of how repairs affect prices under imperfect information. Our model reveals that repairs may lower prices because, if repairs are not always successful, they may reveal negative information about product quality. We also show that the price effect of repairs is increasing in the share of defective products in the ...

Availability of Large Scale Repairable Systems with Imperfect Repair

International Journal of Operations Research and Information Systems, 2014
Operational systems consist of components that deteriorate and eventually fail. Upon failure, components are either repaired or replaced. Cheap and critical components are usually replaced, while expensive and non-critical ones are repaired before replacement. In this research work, repairable systems undergoing imperfect repair are examined where upon

Optimal Inspection Policy for a Three-Stage System With Imperfect Inspection and Repair

IEEE Transactions on Reliability
Many production systems undergo a multistate deterioration process before failure, during which inspection and repair are used to detect and remove the defects.

A bivariate replacement policy for an imperfect repair system based on geometric processes

Proceedings of the Institution of Mechanical Engineers. Part O, Journal of risk and reliability, 2018
A repair replacement model for a deteriorating system with delayed repair is studied, in which the successive working times after repair and the consecutive repair times of the system are described by geometric processes.

Estimating the Reliability of Systems Subject to Imperfect Repair

Journal of the American Statistical Association, 1989
Abstract This study of statistical inference for repairable systems focuses on the development of estimation procedures for the life distribution F of a new system based on data on system lifetimes between consecutive repairs. The Brown—Proschan imperfect-repair model postulates that at failure the system is repaired to a condition as good as new with ...
