Paper Abstract:
|
The WebSys project has developed a method for robustness assessment, using the Failure Mode and
Effect Analysis on use cases, modified by introducing a set of robustness stereotypes developed by I.
Jacobson. The paper gives a short presentation of the method and show how it can be applied by
assessing the robustness of two systems. We then show that the results from testing these two systems
give robustness estimates that are in good agreement with the theoretical result. We have also extended I.
Jacobsons method for analysing robustness to include more complex systems. Based on the FMEA and
the use cases we have also developed a probabilistic analysis framework that uses Bayesian Belief
Network. This can be used to assess the probability of critical failures and to assist the developers in
decision making. |
