The need for high performance, productive and dependable industrial systems has conducted to the design of complex operational architectures. Many features and subsystems are employed and added to a system to produce a fault-tolerant system. All of these subsystems will interact with each other to improve the global 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 paper proposes the use of an integrated modeling approach for fault tolerant systems based on stochastic activity networks. This approach allows the evaluation of some system's performance parameters like the reliability, availability and maintenance costs.
