Abstract: The need for high-performance, productive and dependable industrial systems guided engineers to design complex operational architectures. Many features and subsystems are added to the process to produce a fault-tolerant system. All of these subsystems will interact with each other to improve the whole system’s performances. Each feature/component has its own dynamic and performances, and the interactions between them may induce a difficulty to control and evaluate the system’s behavior. This article proposes the use of an integrated modeling approach for fault-tolerant systems based on stochastic activity networks. It shows how to use this approach to evaluate some system’s performance parameters such as the reliability, availability and maintenance cost.
