Reliability of a system is the probability that it will function as intended for the required period of time. The opposite of reliability is failure probability per unit time or over time, such as a life cycle. Following a review of existing reliability codes and approaches, comprehensive approaches to assess the reliability of offshore structures are described, including probabilistic analysis...

The fault and failure models as well as their semantics within the VLSI community and the distributed systems/algorithms community are quite different. Pointing out the mismatch of those fault respectively failure models is the main part of this work. The impact of the failure model in terms of hardware implementation effort and system complexity will be shown for different VLSI implementations...

Fault Tolerance is a configuration that prevent a computer or network device from failing in the event of unexpected problem or error such as hardware failure, link failure, unauthorized access, variations in the configuration of different systems and system running out of memory or disk space. The integration of fault tolerance measures with scheduling gains much importance. Workflow managemen...

For failure prediction and information interaction problems of multi-equipment health management, fault prediction technology of multi-equipment and multi-parameter was proposed based on the system network. The state judgment and fault diagnosis algorithm is adopted by SOM self-organizing feature map neural network, the network parameters and node structure are changed adaptively, and the real-...

Execution patterns and fault distribution characteristics of a program will aaect the failure process and thus reliability estimates. The failure process of a software system is innuenced by many factors, and traditional software reliability engineering has found it diicult to isolate the eeect of each individual factor. A simulation approach is used to investigate the eeects of fault distribut...

Cloud computing is the result of evolution of on demand service in computing paradigms of large scale distributed computing. It is the adoptable technology as it provides integration of software and resources which are dynamically scalable. These systems are more or less prone to failure. Fault tolerance assesses the ability of a system to respond gracefully to an unexpected hardware or softwar...

This document describes a number of approaches for the dependability characterization of middleware implementations, and in particular failure mode analysis of CORBA ORB implementations. The aim of the work is to provide an overall approach for identifying and quantifying failure modes using various fault injection techniques and fault models. Related work in dependability characterization of e...

This article provides the stochastic and statistical framework to model software reliability in the presence of an operational profile. The software system is used under a randomly changing operational process so that the failure characteristics depend on the specific operation performed. The operational process describes, in a probabilistic sense, how the software is utilized by the users. The...

This paper describes the XSAP safety analysis platform. XSAP provides several model-based safety analysis features for finiteand infinite-state synchronous transition systems. In particular, it supports library-based definition of fault modes, an automatic model extension facility, generation of safety analysis artifacts such as Dynamic Fault Trees and Failure Mode and Effects Analysis tables. ...
