In order to support the conceptualization and specification of simulation models of complex systems, several formalisms or world views exist. Petri nets, differential equations, d...
It has been recognised that formal methods are useful as a modelling tool in requirements engineering. Specification languages such as Z permit the precise and unambiguous modell...
The hybrid χ (Chi) formalism is suited to modeling, simulation and verification of hybrid systems. It integrates concepts from dynamics and control theory with concepts from com...
