Download or read book Reliability of microcomputer systems using triple modular redundancy written by Stanford University Stanford Electronics Laboratories. Digital Systems Laboratory and published by . This book was released on 1975 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Triple Modular Redundancy (TMR) is a classical technique for improving the reliability of digital systems. However, applying TMR to microcomputer systems may not improve overall system reliability because voter circuits may contribute as much to system unreliability as the microprocessors themselves. We examine the issues that affect the effectiveness of TMR for microcomputer systems, including voter unreliability, considerations for transient recovery, and reliability of semiconductor memory systems. With careful application TMR can improve the mission time of a small system by a factor of three or more. (Author).
Download or read book A Reliability Model for Various Switch Designs in Hybrid Redundancy written by Ashok Ingle and published by . This book was released on 1973 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various switch designs for the hybrid redundancy scheme are studied. A reliability model for the switch is developed and the switch is shown to be a significant factor in the overall system reliability. A hybrid redundancy scheme with a triple-modular redundant (TMR) core may have a maximum attainable reliability for only a spare or two. Adding spares complicates the switch enough to cause the system reliability to actually decrease. There exist conditions under which the switch becomes so complex that simple TMR would yield a better solution. Models for fault-tolerant switch designs are also obtained. Finally, various designs are compared via their reliability models. (Author).

This book was released on 2012-12-06 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the editors of this book, as well as for many other researchers in the area of fault-tolerant computing, Dr. William Caswell Carter is one of the key figures in the formation and development of this important field. We felt that the IFIP Working Group 10.4 at Baden, Austria, in June 1986, which coincided with an important step in Bill's career, was an appropriate occasion to honor Bill's contributions and achievements by organizing a one day "Symposium on the Evolution of Fault-Tolerant Computing" in the honor of William C. Carter. The Symposium, held on June 30, 1986, brought together a group of eminent scientists from all over the world to discuss the evolu tion, the state of the art, and the future perspectives of the field of fault-tolerant computing. Historic developments in academia and industry were presented by individuals who themselves have actively been involved in bringing them about. The Symposium proved to be a unique historic event and these Proceedings, which contain the final versions of the papers presented at Baden, are an authentic reference document.

Download or read book A Highly Efficient Redundancy Scheme Self purging Redundancy written by Stanford University Stanford Electronics Laboratories. Digital Systems Laboratory and published by . This book was released on 1975 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goals of this paper are to present an efficient redundancy scheme for highly reliable systems, to give a method to compute the exact reliability of such schemes and to compare this scheme with other redundancy schemes. This redundancy scheme is self-purging redundancy; a scheme that uses a threshold voter and that purges the failed modules. Switches for self-purging systems are extremely simple: there is no replacement of failed modules and module purging is quite simply implemented. Because of switch simplicity, exact reliability calculations are possible. The effects of switch reliability are quantitatively examined. For short mission times, switch reliability is the most important factor: self-purging systems have a probability of failure several times larger than the figure obtained when switches are assumed to be perfect. The influence of the relative frequency of the diverse types of failures (permanent, intermittent, stuck-at,...) are also investigated. Reliability functions, mission time improvements and switch efficiency are displayed. Self-purging systems are compared with ot her redundant systems, like hybrid or NMR, for their relative merits in reliability gain, simplicity, cost and confidence in the reliability estimation. The high confidence in the reliability evaluation of self-purging systems makes them a standard for the validation of several models that have been proposed to take into account switch reliability. The accuracy of models using coverage factors can be evaluated that way.

Download or read book Systems Engineering written by Mangey Ram and published by CRC Press. This book was released on 2019-04-18 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: A substantial amount of research has been conducted on consecutive k-out-of-n and related reliability systems over the past four decades. These systems have been used to model various engineering systems such as the microwave stations of telecoms network, oil pipeline systems, and vacuum systems in an electron accelerator. As such, studies of reliability properties of consecutive k-out-of-n structures have attracted significant attention from both theoretical and practical approaches. In the modern era of technology, the redundancies are employed in the various industrial systems to prevent them from failure/sudden failure or to recover from failures. This book is meant to provide knowledge and help engineers and academicians in understanding reliability engineering by using k-out-of-n structures. The material is also targeted at postgraduate or senior undergraduate students pursuing reliability engineering.
Download or read book Complex System Reliability written by Albert Myers and published by Springer. This book was released on 2011-03-23 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complex System Reliability presents a state-of-the-art treatment of complex multi-channel system reliability assessment and provides the requisite tools, techniques and algorithms required for designing, evaluating and optimizing ultra-reliable redundant systems. Critical topics that make Complex System Reliability a unique and definitive resource include: • redundant system analysis for k-out-of-n systems (including complex systems with embedded k-out-of-n structures) involving both perfect and imperfect fault coverage; • imperfect fault coverage analysis techniques, including algorithms for assessing the reliability of redundant systems in which each element is subject to a given coverage value (element level coverage) or in which the system uses voting to avoid the effects of a failed element (fault level coverage); and • state-of-the-art binary decision diagram analysis techniques, including the latest and most efficient algorithms for the reliability assessment of large, complex redundant systems. This practical presentation includes numerous fully worked examples that provide detailed explanations of both the underlying design principles and the techniques (such as combinatorial, recursive and binary decision diagram algorithms) used to obtain quantitative results. Many of the worked examples are based on the design of modern digital fly-by-wire control system technology. Complex System Reliability provides in-depth coverage of systems subject to either perfect or imperfect fault coverage and also the most recent techniques for correctly assessing the reliability of redundant systems that use mid-value-select voting as their primary means of redundancy management. It is a valuable resource for those involved in the design and reliability assessment of highly reliable systems, particularly in the aerospace and automotive sectors.

Available in PDF, EPUB and Kindle. Book excerpt: This study is concerned with the reliability analysis of commonly used repairable and non-repairable redundant systems (with common-cause failures) such as parallel, k-out-of-n and standby with identical and non-identical units. Formulas for steady state system availability, system reliability and system mean time to failure are developed. The variation of steady state system availability, system reliability and system mean time to failure with common-cause failures is shown by means of plots for the above mentioned configurations. This study clearly shows that the occurrence of common-cause failures has a negative effect on system reliability parameters.
