چکیده
Our society is faced with an ever increasing dependence on computing systems, which lead to question ourselves about the limits of their dependability, and to attempt to identih avenues fo r improving the situation. In order to respond these questions, a global conceptual and terminological framework is needed, which is first given. The limits in dependability are then addressed, from technical and financial viewpoints. The identification of design faults as the current major bottleneck fo r dependability leads to a ) address the limits in software reliability and in fault tolerance efectiveness, and to b ) suggest a dependability-explicit

ANTIRANDOM TESTING: GETTING THE MOST OUT OF BLACK-BOX TESTING - Software Reliability Engineering, 1995. Proceedings., Sixth International Symposium on
Random testing is a well known concept that requires that each test is selected randomly regardless of the test previously applied. This paper introduces the concept of antirandom testing. In this testing strategy each test applied is chosen such that its total distance from all previous tests is maximum. Two distance measures are defined. Procedures to construct antirandom sequences are develo...

متن کاملDependability assessment for decentralized systems
Conventional dependability measures, such as reliability or availability, assume that the equipment characterized by the measure is either operational or has failed. This dichotomy does not hold for decentralized or distributed systems because these can operate in modes in which partial or degraded service is furnished. Whether a specific degraded mode should be counted as "operational" or "fai...
متن کاملFundamental Concepts of Computer System Dependability
Dependability is the system property that integrates such attributes as reliability, availability, safety, security, survivability, maintainability. The aim of the presentation is to summarize the fundamental concepts of dependability. After a historical perspective, definitions of dependability are given. A structured view of dependability follows, according to a) the threats, i.e., faults, er...
متن کاملWorkshop on Interdisciplinary Approaches to Achieving and Analysing System Dependability
Many current and expected problems in system dependability push the limits of the practical techniques, research methods and scientific knowledge that are familiar to the DSN audience. Computer-based systems involve a complex interaction of technical and human components set in the context of a physical environment. Unanticipated problems arise as emergent properties of the interplay between th...
