36 Computer Toward a More Reliable Theory of Software Reliability S oftware development and testing is an error-prone process. Despite developers’ best attempts at checking every detail, errors made during development often cause postrelease software failures. Software reliability theory is one of industry’s seminal approaches for predicting the likelihood of software field failures. Unfortunat...

The influence factors of reliability for drivers in different running stage are analyzed in the paper, firstly, based on Behavior-causing Theory. Then a new quantification method on transience reliability for drivers is advanced by a new definition “reliability degree”, whose error rate is calculated by the response time of drivers, and the influence factors how to influent the transience relia...

He previously worked at TASC and AT&T Bell Laboratories. Dr. Feinberg has actively published in the area of reliability physics since 1986 and at the IEST on a wide variety of topics from accelerated reliability grow...

Reliability theory bases on the concept of boolean components, i.e. of up, operating or down, failed components. But often such assumption is not adequate for modeling specific behaviors of components, units, subsystems and systems. It cannot catch, for example, different operating conditions of components due to dependencies on other components or environment variations. Aim of this paper is t...

-The performance in terms of reliability of multi-server computer networks motivates this paper. The probability limit theorem is derived on the virtual waiting time of job in nodes in a multi-server open queueing network and applied to a reliability model for multi-server computer networks where we relate the time of failure of a multi-server computer network to the system parameters. Key-Word...

In the field of system health monitoring, system performance degradation or fault occurrence will decrease the system reliability to some degree. However, traditional reliability analysis is of limited usefulness in evaluating the reliability of an individual product under dynamic operating and environmental conditions. In this case, research on performance reliability as well as real-time reli...

A loose **classification** of longevity theories would separate the functional theories — how senescence proceeds in the individual organism — from the teleological theories, which seek to explain why a given pattern of senescence ought to be so, usually from the evolutionary perspective. We focus here on the loose class of functional theories allied to engineering reliability theory. The link ...

Research in traditional reliability theory is based mainly on probist reliability, which uses a binary state assumption and classical reliability distributions. In the present paper the binary state assumption has been replaced by a fuzzy state assumption, thereby leading to profust reliability estimates of a repairable system, which is modeled as a four unit gracefully degradable system using ...
