Abstract: Several different kinds of performance models can be generated from sets of scenarios that describe typical responses of a system, and their use of re-sources. The Core Scenario Model described here integrates the scenario and resource elements defined in a UML model with performance annotations, preparatory to generating performance models. It is based on, and aligned with the UML Profile for Schedulability, Performance and Time, and supports the generation of predictive performance models using queueing networks, layered queueing, or timed Petri nets. It is proposed to develop it as an intermediate language for all performance formalisms.
