Model-based analysis is a well-established method to assess the dependability of a system before deployment. It is well known that, in highly dynamic contexts, the accuracy of the analysis results can be limited because unpredictable phenomena may affect the system during its operation. In such contexts, the analysis typically needs to be refined with data obtained from real system executions. In...
Architecture-based software reliability analysis methods shall help software architects to identify critical software components and to quantify their influence on the system reliability. Although researchers have proposed more than 20 methods in this area, empirical case studies applying these methods on large-scale industrial systems are rare. The costs and benefits of these methods remain unknown...
Future network infrastructure systems demand an extensible, continuous design framework to readily incorporate emerging technologies. Other domains have addressed this demand by moving towards an open design and development approach to capture the ingenuity of a community of developers. Yet, the design and development of current network infrastructure systems remains predominately closed. In this...
An early prediction of resource utilization and its impact on system performance and reliability can reduce the overall system cost, by allowing early correction of detected problems, or changes in development plans with minimized overhead. Nowadays, researchers are using both academic and commercial models to predict such attributes, by measuring them at earliest stages of system development. In...
Component-based software reliability analysis typically takes the reliability of component as an invariable property of component itself, disregards the fact that it changes when the component context it interacts changes due to a different operational profile of the system. This paper introduces a subdomain-based analysis approach to characterize the component into path-based architectural reliability...
The process can fail to deliver its expected outputs and consequently contribute to the introduction of faults into the software system. The process may fail due to ambiguous and unsuitable notations, unreliable tool-support, flawed methods and techniques or incompetent personnel. However, not all process activities pose the same degree of risks and therefore require the same degree of rigour. In...
