Software reliability assessment using accelerated testing methods
The use of operational pro®les and usage-based testing has received considerable attention recently in the software engineering literature. Testing under the actual operational pro®le can, however, be expensive, time consuming or even infeasible in situations where the performance of a system is dominated by infrequent but highly critical events. We consider a real application that deals with t...
متن کاملAccelerated Testing for Software Reliability Assessment
It is necessary to assess the reliability of safety-critical systems to a high degree of confidence before they can be used in the field. One theoretically sound approach for assessing software reliability is to use statistical sampling according to the operational profile. However, this method requires a prohibitive amount of testing. To make this approach more feasible, it is necessary to red...

15 صفحه اولA Bayes approach to step-stress accelerated life testing
Conclusions This article develops a Bayes model for step-stress accelerated life testing. The failure times at each stress level are exponentially distributed, but the specification of strict adherence to a time transformation function is not required. Rather, prior information is used to define indirectly a multivariate prior distribution for the failure rates at the various stress levels. Ou...
متن کاملBayesian Accelerated Life Testing
In this paper a Bayesian approach for accelerated life testing will be considered. It will be assumed that the failure times at the different stress levels follow a Weibull distribution and exponential distribution, respectively. In accelerated life tests, the components are exposed to an environment that is more severe that the usual environment, such that the components will fail in a shorter...
