Although sound performance analysis theories and techniques exist, they are not widely used because they require extensive expertise in performance modeling and measurement. The overall goal of our work is to make performance modeling more accessible

Research and development (R&D) of new tools for performance analysis faces many challenges from immaturity and lack of documentation of supporting tools and infrastructure, incompatibility of tools, lack of access to realistic case studies and perfor

When real-time embedded systems fail: patients die, warships shoot passenger jets, airplanes crash, cars stop on freeways or accelerate uncontrollably, and other documented problems. Preventing these problems saves lives, money, enables faster delive

XML-based interchange formats for performance models provide a mechanism whereby performance model information may be transferred among modeling tools. Formats have been defined for the interchange of queueing network models (QNM), layered queueing n

The Performance Model Interchange Format (PMIF) provides a mechanism for transferring the system model information among performance modeling tools requiring only that the tools either internally support PMIF or provide an interface that reads/writes

Quantitative design is crucial to ICT and it is therefore important to integrate performance modelling techniques into support environments that facilitate the correct construction of computer systems. We consider Performance Modelling Interchange Fo

An extension to the Performance Model Interchange Format (PMIF+) to move models among tools has been recently introduced. The original PMIF was limited to models solvable with efficient, exact solution methods such as mean value analysis and product

We consider a form of blocking, which is typical in client-server systems including those implemented under the Enterprise JavaBean (EJB) specification. The novel feature is that tasks must wait for one of a number of parallel queues to clear its out

During early phases of design and implementation, not all the parameter values of a performance model are usually known exactly. In related research contributions, intervals have been proposed as a means to capture parameter uncertainties. Existing m
