Abstract:

In traditional development processes, each type of analysis is generally based on a dedicated model, which requires substantial amount of training to be used effectively. Performing dependability evaluation along with other analyses at architectural level allows both making architectural tradeoffs and predicting the effects of architectural decisions on the dependability of an application. This paper is related to the building of dependability models for architectural software systems using the AADL (Architecture Analysis and Design Language). It presents reusable modeling patterns for fault-tolerant applications and shows how the presented patterns can be used in the context of a subsystem of a real-life application.
