Abstract:
Abstract Ignoring the problem of imperfect fault coverage of fault-tolerant systems will lead to reliability evaluation errors. In order to accurately assess the reliability of the fault-tolerant design of airborne computing platform, the fault-coverage process and failure factors were analyzed, and a discrete event simulation model for the problem of imperfect fault coverage is constructed. In the discrete event simulation model, the fault, detection, isolation and recovery behaviours event are generated by random sampling according to specific distribution, and each discrete event is used to

Abstract:
This study presents a reliability and availability analysis of a multi-component machining system subject to service interruptions, imperfect coverage, and a reboot mechanism. The system comprises multiple identical components, each susceptible to random failures. A single repair server addresses these failures under a first-come-first-served policy. Upon a failure, there is a probability that the fault is detected and covered; otherwise, an uncovered failure leads to service interruption and triggers a system reboot. The model employs a Continuous-Time Markov Chain (CTMC) framework, utilizing

Abstract:
ABSTRACTIn this research article, we thoroughly examine the dynamics of a repairable system, emphasizing a two‐unit configuration through a Bayesian perspective. The study integrates diverse prior distributions to model the uncertainty of unknown parameters, incorporating the coverage factor as a probabilistic measure of successful recovery from operational unit failures. The temporal characteristics of unit failure and repair are modeled using exponential distributions, ensuring analytical tractability and robustness. The repair process is bifurcated into two distinct phases: fault detection

Abstract:
In systems with Imperfect Fault Coverage (IFC), all components are subject to uncovered failures, possibly threatening the whole system. Therefore, to improve the system reliability, it is important to timely detect, identify, and shut down the components that are no more relevant for the system operation. Thus, the Irrelevance Coverage Model (ICM) was proposed based on the Imperfect Fault Coverage Model (IFCM). In the ICM, any component detected as irrelevant can be safely shut down without reducing the system reliability and preventing the case where its eventual failure may remain uncover

Abstract:
This research tackles the problem of complicated machine repair systems by proposing a probabilistic model that takes into account incomplete fault coverage and unreliable servers. With imperfect fault coverage, which is represented by probability c, there is a chance that a fault will go unnoticed or unfixed while the system is being repaired. Incorporating a server that isn't reliable increases system uncertainty since the server's reliability affects how well the repair procedure works overall. Using a system of differential equations, the mathematical model captures the transitions between operational, degraded, and failed states with precision. Another aspect that might cause states to transition is when humans make mistakes while fixing things. Examining the effects of server reliability and imperfect fault coverage on system availability, performance, and reliability over time is the primary goal of the study. We may learn more about the machine repair system's dynamic behaviour under various conditions from the simulation findings. In order to determine how well the system handles variations in server reliability and the possibility of incomplete fault coverage, sensitivity assessments are run. If system designers and maintenance professionals want to optimise strategies for making machine repair operations more reliable and available, the results are significant information. Practical applications of machine repair systems involve uncertainties relating to fault coverage and server dependability; this research adds to our understanding of these factors. Integrating probabilistic components into the study allows for a more accurate portrayal of actual machine repair situations, which in turn allows for better decisions about system design and maintenance planning.
