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 ...

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.

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.

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 ...

Steady-state imperfect repair models
European Journal of Operational Research, 2020 Imperfect maintenance models are widely used in reliability engineering. This paper discusses relevant asymptotic properties for the steady-state virtual age processes. It is shown that the limiting distributions of age, the residual lifetime and the spread that describe an ordinary renewal process can be generalized to the stable virtual age process ...

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 ...

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 ...

A testing-coverage software reliability model considering fault removal efficiency and error generation. [PDF]
PLoS ONE, 2017 In this paper, we propose a software reliability model that considers not only error generation but also fault removal efficiency combined with testing coverage information based on a nonhomogeneous Poisson process (NHPP).
