Severalconferenceand workshopseriesarededicated to formalcomponent m- els and their use in veri?cation and quality prediction, such as FMCO, CBSE, FESCA,FACS andQoSA. There are a plethoraof componentmodels published, all with speci?c merits and bene?ts. However, most often these models are not used for comparison, as each research group concentrates on di?erent aspects of formal component modelling and quality prediction. Like the famous pro- 1 duction cell approach of the FZI, Karlsruhe, which has served since 1995 as a common example for di?erent embedded systems safety veri?cation, in this v- ume we de?ne a commonexample for modelling approachesof component-based systems. This Common Component Modelling Example enables the compa- bility of di?erent approaches, the validation of existing models, a better focus of research to tackle aspects less frequently dealt within the classi?cation of - isting models and approaches, an eased interchange of research ideas, as well as a simpli?ed and increased coordination and research collaborations to join complementary models and approaches. In this volume we de?ne the Common Component Modelling Example and present the models in current modelling and analysis approaches. The book concludes with comments on each modelling approach by an international jury. August 2007 Andreas Rausch Ralf Reussner Ra?aela Mirandola Franti? sek Pl¿ a? sil 1 Springer LNCS vol. 891.
