A device is repaired at failure. With probability p, it is returned to the ‘good-as-new' state (perfect repair), with probability 1 – p, it is returned to the functioning state, but it is only as good as a device of age equal to its age at failure (imperfect repair). Repair takes negligible time.

A 2-unit System with "Imperfect" Repair
Mathematische Operationsforschung und Statistik. Series Optimization, 1980In the study of repairable systems, it is usually assumed that a unit is ‘new’ after repair. While this assumption simplifies the analysis of such systems, there are many instances, in which this assumption is not true. In this paper, we study a 2-unit cold standby redundant system, In which the number of repairs that can be done for each unit is h and

Imperfect Repair and Lifesaving in Heterogeneous Populations
Reliability Engineering and System Safety, 2007In this theoretical paper we generalize the notion of minimal repair to the heterogeneous case, when the lifetime distribution function can be modeled by continuous or a discrete mixture of distributions. The statistical (black box) minimal repair and the minimal repair based on information just before the failure of an object are considered.

We consider models of systems of components with dependent life-lengths having certain multivariate distributions. Upon failure, components are repaired. Two types of repair are possible. After perfect repair, a unit has the same life distribution as a new item.

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 ...

Multivariate age‐dependent imperfect repair
Naval Research Logistics (NRL), 1991AbstractIn this article we consider models of systems whose components have dependent life lengths with specific multivariate distributions. Upon failure, components are repaired. Two types of repair are distinguished. After perfect repair, a unit has the same life distribution as a new item.

Cost Evaluation for an Imperfect-Repair Model With Random Repair Time
International Journal of Systems Science, 2005A repair can bring the state of a failed system to a level which is somewhere between new and prior to repair. In most repair models proposed in the literature so far, the repair time is assumed to be negligible, and so the length of repair time has not been a factor in developing the maintenance models.

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

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 ...
