Generating a Performance Stochastic Model From UML Specifications
Since its initiation by Connie Smith, the process of Software Performance Engineering (SPE) is becoming a growing concern. The idea is to bring performance evaluation into the software design process. This suitable methodology allows software designers to determine the performance of software during design. Several approaches have been proposed to provide such techniques. Some of them propose to derive from a UML (Unified Modeling Language) model a performance model such as Stochastic Petri Net (SPN) or Stochastic process Algebra (SPA) models. The Paper belongs to the same category. The authors propose to derive from a UML model a Stochastic Automata Network (SAN) in order to obtain performance predictions. The approach is more flexible due to the SAN modularity and its high resemblance to UML' state-chart diagram.
