    Hybrid reliability modeling of fault-tolerant computer systems. Applied computing. and (3) provision of automatic sensitivity analysis of system reliability with respect to parametric and initial state errors. Thus, this is an elegant solution to the reliability prediction problem, and it removes many serious limitations of previous models Author: TrivediKishor, Bechta DuganJoanne, GeistRobert, SmothermanMark. Basic concepts, motivation, and techniques of fault tolerance are discussed in this paper. The topics include fault classification, redundancy techniques, reliability modeling and prediction, examples of fault-tolerant computers, and some approaches to the problem of tolerating design by:

    To achieve the needed reliability and availability, we need fault-tolerant computers. They have the ability to tolerate faults by detecting failures, and isolate defect modules so that the rest of the system can oper-ate correctly. Reliability techniques have also become of increasing interest to general-purpose computer Size: KB. Page 3 (C) Daniel J.

Sorin 6 Motivation • Fault tolerance has always been around – NASA’s deep space probes – Medical computing devices (e.g., pacemakers) – But this had been a niche market until fairly recently.

    Reliability evaluation by analytic modelling constitute an important issue of designing a reliable multiprocessor system. In this thesis, a model for reliability and fault tolerance analysis of the interconnection network is presented, based on graph theory. Reliability and fault tolerance are. Markov modeling is a modeling technique that is widely useful for dependability analysis of complex fault tolerant sys- tems. It is very flexible in the type of systems and system behavior it can model, it is not, however, the most appropri- ate modeling technique for every modeling Size: 2MB.

Fault-tolerant computer systems. Although capable of tolerating certain faults, these systems are still susceptible to failure. Thus, the reliability of these systems must be evaluated to ensure that requirements are met.

The reliability analysis of a fault-tolerant computer system is a File Size: 4MB. The reliability analysis of a fault-tolerant computer system is a complex problem. A life- testing approach is typically used to determine the reliability or "lifetime" of a diversity of.

The art of fault-tolerant system reliability modeling. A step-by-step tutorial of the methods and tools used for the reliability analysis of fault-tolerant systems is presented. Emphasis is on the representation of architectural features in mathematical models.

Details of the mathematical solution of complex reliability models are not presented. Instead the use of several recently developed computer programs--SURE, ASSIST, STEM, PAWS--which.

Mean Time To Failure (MTTF) is an important reliability index of Fault Tolerant Control Systems (FTCS's). This paper discusses controller design based on MTTF optimization. The opportunity for fast recovery in the event of a fault is greatly aided with the advent of high-speed microprocessors, but new challenges arise regarding reliable synchronization.

One other challenge to fault-tolerant design is the increased use of massively parallel : Dhiraj K. Pradhan. We further incorporate such formulation into traditional reliability growth models, not only for fault-tolerant software, but also for general software system.

Our empirical evaluations show that our new reliability model can achieve more accurate reliability assessment than the traditional Non-homogenous Poisson model. Reliability modeling of fault tolerant control systems long-term system reliability behavior during an off-line analysis.

As a function criterion, R(t) is not often. The field of model-driven engineering of reliable fault-tolerant systems, requires knowledge from the areas of software engineering, system verification, fault-tolerant systems, and distributed systems.

[Ricky W Butler; Sally C Johnson; Langley Research Center.]. Fault-Tolerant Systems is the first book on fault tolerance design with a systems approach to both hardware and software. No other text on the market takes this approach, nor offers the comprehensive and up-to-date treatment that Koren and Krishna provide.

Reliability Modeling of Fault Tolerant Control Systems This paper proposes a novel approach to reliability evaluation for active Fault Tolerant Control Systems (FTCSs).

By introducing a reliability index based on the control performance and hard deadline, a semi-Markov process model is proposed to describe system operation for reliability Cited by: Abstract: This paper presents a framework for modeling the dependability of hardware and software fault-tolerant systems, taking into account explicitly the dependence among the components.

These dependencies can result from: (a) functional or structural interactions between the components or (b) interactions due to global system reconfiguration and maintenance strategies. This textbook serves as an introduction to fault-tolerance, intended for upper-division undergraduate students, graduate-level students and practicing engineers in need of an overview of the field.

Readers will develop skills in modeling and evaluating fault-tolerant architectures in terms of reliability, availability and : Springer-Verlag New York. System reliability is an important aspect of real-time systems, because the result of a real-time application may be valid only if the application functions correctly and its timing constraints are satisfied.

There are two kinds of faults, hardware and software faults, Cited by: 2. Fault tolerance is an approach by which reliability of a computer system can be increased beyond what can be achieved by traditional methods.

While hardware supported fault tolerance has been well-documented, the newer, software supported fault tolerance techniques have remained scattered throughout the literature. Comprehensive and self-contained, this book organizes that body of Cited by:. Formal Techniques in Real-Time and Fault-Tolerant Systems focuses on the state of the art in formal specification, development and verification of fault-tolerant computing systems.

The term `fault-tolerance' refers to a system having properties which enable it to deliver its specified function despite (certain) faults of its subsystem.We found that a reliability model commonly used to estimate Mean-Time-To-Data-Loss(MTTDL), while suitable for modeling RAID 0 and RAID 5, fails to ac-curately model systems having a fault-tolerance greater than 1.

Therefore, to model the reliability of RAID 6, Triple-Replication, ork-of-n systems requires an alter-nate by: 3.Fault-Tolerant Systems Abstract: Basic concepts, motivation, and techniques of fault tolerance are discussed in this paper.
