UML-JMT: A Tool for Evaluating Performance Requirements

Software performance assessment is a very important task especially in the architectural design stage of software development. Software engineers must be supplied with techniques and tools that will allow them to complete this task without the extra cost of hiring quality assurance experts. This paper proposes the UML-JMT tool which provides functionalities for studying the expected performance characterisations of an architectural design. The UML-JMT tool uses the architectural design models as building blocks for an equivalent performance extended queuing network model (ENQ). This ENQ will be solved and analysed using the tools available in the JMT suite. In this paper we will explain the theoretical and technical aspects of the UML-JMT tool and we will use an example to explain the performance study steps and validate the results of this tool.
