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 ...

Optimal maintenance policies under different operational schedules [PDF]
, 2005 In the reliability literature, maintenance time is usually ignored during the optimization of maintenance policies. In some scenarios, costs due to system failures may vary with time, and the ignorance of maintenance time will lead to unrealistic results.

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.

Maintenance Optimization for Repairable Deteriorating Systems under Imperfect Preventive Maintenance
Mathematics, 2019 This study deals with the preventive maintenance optimization problem based on a reliability threshold. The conditional reliability threshold is used instead of the system reliability threshold.

Cost-Benefit Analysis of a Two-Unit Cold Standby System with Imperfect Repair Man and Abnormal Weather Conditions [PDF]
Alfarama Journal of Basic & Applied Sciences, 2023 This study examines the dependability of a cold standby system made up of two similar units. One of the two units is always in use, and the other unit is on cold standby. The repairman could be present or not at the job site.

Mathematics, 2021 Traditionally, the inventory models available in the literature assume that all articles in the purchased lot are perfect and the demand is constant. However, there are many causes that provoke the presence of defective goods and the demand is dependent ...

On the Maintenance Modeling of a Hybrid Model with Exponential Repair Efficiency [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2021 In the reliability literature, maintenance efficiency is usually dealt with as a fixed value. Since repairable systems are subject to different degrees and types of repair, it is more convenient to regard a random variable for maintenance efficiency ...

IEEE Access, 2019 In this paper, we investigate an imperfect maintenance optimization problem for a multi-state, Markovian deterioration system with obvious failures under repair restriction based on those non-periodically collected sensor information.

Bagging Recurrent Event Imputation for Repair of Imperfect Event Log With Missing Categorical Events
IEEE Transactions on Services Computing, 2023 In most computing services, imperfect event logs with missing events are generated for a variety of reasons. Because missing events in imperfect event logs adversely affect the results of process mining analysis, it is essential to handle them ...

Hell Hath No Fury: The Place of Revenge in Moral Repair
Passion, 2023 Revenge is a powerful word. It can conjure up the scheming, embittered individual, plotting the downfall of his enemies well beyond reason and morality – or, more seriously, tragic cycles of violence and blood vendettas, spiraling into entrenched civil ...
