Decline and repair, and covariate effects [PDF]
, 2015 The failure processes of repairable systems may be impacted by operational and environmental stress factors. To accommodate such factors, reliability can be modelled using a multiplicative intensity function.

On the combined imperfect repair process
Probability in the Engineering and Informational Sciences, 2023 AbstractIn this paper, a new point process is introduced. It combines the nonhomogeneous Poisson process with the generalized Polya process (GPP) studied in recent literature. In reliability interpretation, each event (failure) from this process is minimally repaired with a given probability and GPP-repaired with the complementary probability ...

Supporting group maintenance through prognostics-enhanced dynamic dependability prediction [PDF]
, 2017 Condition-based maintenance strategies adapt maintenance planning through the integration of online condition monitoring of assets. The accuracy and cost-effectiveness of these strategies can be improved by integrating prognostics predictions and ...

Nonparametric Methods for Imperfect Repair Models
The Annals of Statistics, 1992 An appropriate probability model for the age-dependent minimal repair model of \textit{H. W. Block}, \textit{W. S. Borges} and \textit{T. H. Savits} [J. Appl. Probab. 22, 370-385 (1985; Zbl 0564.60084)] is developed and a counting process approach is used to extend the large sample theorems of \textit{L. R. Whitaker} and \textit{F. J. Samaniego} [J. Am.

Imperfect Maintenance Policy for a Two-Machine One-Buffer System Based on Markov Decision Process
Shanghai Jiaotong Daxue xuebao, 2021 To solve the problem of machine maintenance optimization of degraded systems, the preventive maintenance policy of a two-machine one-buffer production system is studied. First, random degradations of both machines are considered.

Enhancement of homology-directed repair with chromatin donor templates in cells. [PDF]
, 2020 A key challenge in precise genome editing is the low efficiency of homology-directed repair (HDR). Here we describe a strategy for increasing the efficiency of HDR in cells by using a chromatin donor template instead of a naked DNA donor template.

Maintenance Modeling for a Multi-State System Under Competing Failures and Imperfect Repairs
MathematicsA condition-based maintenance modeling approach is proposed for a multi-state system under competing failures and imperfect repairs. The system experiences three states (normal, defective and failed) over its lifecycle. Two competing failure processes, i.
