Responsiveness of Multi-Channel IEC-61850 Substation Communication Network Reliability Performance to Changes in Repair Factors

open access: yesIEEE Access, 2021
Power distribution centres distribute power to motor control centres in industrial facilities, as well as supply power to medium voltage drives among other loads. In reliability studies, the use of the combinatorial methods to evaluate the reliability of

Enhancement of homology-directed repair with chromatin donor templates in cells. [PDF]

open access: yes, 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.

On the combined imperfect repair process

open access: yesProbability 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 ...

On the Maintenance Modeling of a Hybrid Model with Exponential Repair Efficiency [PDF]

open access: yesInternational 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 ...

Maintenance Optimization for Repairable Deteriorating Systems under Imperfect Preventive Maintenance

open access: yesMathematics, 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.

Steady-state imperfect repair models

open access: yesEuropean 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 ...

An Inventory Model for Imperfect Quality Products with Rework, Distinct Holding Costs, and Nonlinear Demand Dependent on Price

open access: yesMathematics, 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 ...

An Optimal Imperfect Maintenance Policy for a Partially Observed System With Obvious Failures and Limited Repairs

open access: yesIEEE 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.
