....behaviors of the system are captured. Starting from this new combined diagram a Generalized Stochastic Petri Net model is generated. The direct generation of a continuous time Markov chain starting from Collaboration and State Diagrams is also investigated in [6] through a simple example. In [10, 11] the extension of the UML notation to performance annotations (pa UML) has been proposed to deal with performance of software systems. A set of transformation rules is then given to obtain Generalized Stochastic Petri nets from pa UML diagrams. Performance indices are derived from classical ....

....(paUML) 8] to deal with performance skills on these kind of systems. Our approach to solve the problem is as follows: we model the problem domain using paUML in conjunction with design patterns [5] describing static and dynamic views when necessary (preliminary ideas were presented in [7]) The paUML models will give us the necessary background to semi automatically obtain the corresponding formal model expressed as Petri nets [10] From paUML, we derive, by applying a set of rules, a time interpretation of Petri nets leading to Generalized Stochastic Petri Nets (GSPN) 2] Thus, ....

....system. A use case diagram, a sequence diagram and several statechart diagrams, one for each agent present in the system, will be modelled; all them represent the dynamic view of the system. In order to express the system load, the diagrams have been enriched following the notation presented in [14, 13]. It must be noted that for this case study all the system load can be represented in the dynamic view of the system, avoiding the necessity to develop a static view, which could be appropriately represented using a class diagram. Figure 2 shows the only use case needed to describe the dynamic ....

....In this way, without much e ort, the process allows to obtain a performance model as a by product and it preserves the bene ts of the software design methodologies. A complementary approach to obtain the performance model, based on design patterns [9] is being developed, it can be found in [12]. The performance of a system is traditionally obtained from its dynamic view. So, we concentrate on developing the UML diagrams corresponding to the dynamic model. Unfortunately, UML lacks of the necessary expressiveness to accurately describe the system load, which is needed to obtain ....
