ALICE, the experiment dedicated to the study of heavy ion collisions at the LHC, uses an object-oriented framework for simulation, reconstruction and analysis (AliRoot) based on ROOT. Here, we describe the general ALICE simulation strategy and those components of the framework related to simulation. Two main requirements have driven the development of the simulation components. First, the possibility to run different transport codes with the same user code for geometry and detector response has led to the development of the Virtual Monte Carlo concept. Second, simulation has to provide tools to efficiently study events ranging from low-multiplicity pp collisions to Pb-Pb collisions with up to 80000 primary particles per event. This has led to the development of a variety of collaborating generator classes and specific classes for event merging.
