ALICE Simulation Framework

<P>Proposal of abstract for CHEP2000<P>ALICE uses an object oriented framework for simulation and reconstruction based on ROOT (AliRoot).<BR>Here, we describe those components of the class design that represent common concepts of simulation, such as particle generation and transport, detector response and detector segmentation. Applications for fast and slow physics and detector performance simulations as well as the relevance of the design for visualisation and the link of simulation to reconstruction are discussed.
