Investigating dynamic reliability and availability through state–space models

Reliability & Availability Models

Reliability and Availability Analysis of Fusion Power Plants

Major efforts are underway to develop fusion energy for use in electric power production in the furture. While fusion reactor concepts are being developed, appropriate attention must be given to problems relvant to the utility requirements which are likely to be encountered in the commercialization phase. In this paper the expected fusion plant availability is assessed in detail due to the impo...

Monte Carlo Simulation of Computer System Availability/Reliability Models

In recent years, there has been an increased interest in evaluating the availability and reliability of computer systems. For this purpose, we have developed a state of the art modeling package called SAVE (System Availability Estimator). This package has refined numerical matrix methods for computing the dependability measures of interest. These methods do, however, have their limitations sinc...

Increasing Reliability through Dynamic Virtual Clustering

In a scientific community that increasingly relies upon High Performance Computing (HPC) for large scale simulations and analysis, the reliability of hardware and applications devoted to HPC is extremely important. While hardware reliability is not likely to dramatically increase in the coming years, software must be able to provide the reliability required by demanding applications. One way to...

Robot Reliability Through Fuzzy Markov Models

In the past few years, new applications of robots have increased the importance of robotic reliability and fault tolerance. Standard approaches of reliability engineering rely on the probability model, which is often inappropriate for this task due to a lack of su cient probabilistic information during the design and prototyping phases. Fuzzy logic o ers an alternative to the probability paradi...
