Repair-Limit Risk-Free Warranty Policies With Imperfect Repair
IEEE Transactions on Systems, Man, and Cybernetics - Part A: Systems and Humans, 2005The current competitive market environment requires manufacturers to continuously provide better service and support. As a result, warranty considerations emerge as a significant instrument for increasing product marketability. In this paper, we propose a new warranty policy, the repair-limit risk-free warranty with a threshold point on the number of ...

We consider two main approaches for modeling of imperfect repair processes. The first approach is via the modeling of conditional intensities, which combines in some sense the features of the “extreme” repair processes, RP and NHPP. The second approach is via the notion of effective ages, where the idea is that repairs may result in improved system ...

Repairs under imperfect information
Journal of Urban Economics, 2013Abstract 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 ...

DISCRETE REPAIR-COST LIMIT REPLACEMENT POLICIES WITH/WITHOUT IMPERFECT REPAIR [PDF]
Asia-Pacific Journal of Operational Research, 2008 This paper addresses statistical estimation problems of the optimal repair-cost limits minimizing the long-run average costs per unit time in discrete seting. Two discrete repair-cost limit replacement models with/without imperfect repair are considered.

Bayesian imperfect repair model
Communications in Statistics - Theory and Methods, 1998An imperfect repair model proposed by Brown and Proschan(J. Appl. Prob. 20. 1983) is extended in this paper. We propose a new Bayesian imperfect repair model where the probability of perfect repair, P, is considered to be a random variable. Assuming that P has a prior distribution Π(p), we obtain the distribution of waiting times between two successive

Availability of Large Scale Repairable Systems with Imperfect Repair
International Journal of Operations Research and Information Systems, 2014Operational 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

An imperfect repair strategy for two-dimensional warranty
Journal of the Operational Research Society, 2012The objective of this study is to develop a warranty servicing strategy, based on imperfect and minimal repairs, that minimises the total warranty servicing cost. For pre-specified degrees of repair, the expected warranty servicing cost is minimised by optimally partitioning a two-dimensional rectangular warranty region into n disjoint subregions.

Estimating the Reliability of Systems Subject to Imperfect Repair
Journal of the American Statistical Association, 1989Abstract 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 ...
