Modelling and performance analysis of component-based systems
Assessment of dependability of component-based systems must include verification of temporal and performance requirements as they can be of primary importance for many real-time and embedded systems. This paper uses labelled timed Petri nets as models of the behaviour of components at their interfaces. These component models are systematically composed into an integrated model of the system which is used for verification of temporal characteristics and performance analysis.
