Abstract: The interesting but difficult phenomenology of supersymmetric models at theLHC and ILC demands a corresponding complexity and maturity from simulationtools. This includes multi-particle final states, reducible and irreduciblebackgrounds, spin correlations, real emission of photons and gluons, virtualcorrections etc. Most of these topics are included in the multi-particle MonteCarlo MC Event generators Madgraph, WHIZARD and Sherpa. A comparison of thesecodes is shown, with a special focus on the new release of WHIZARD. I showexamples for the necessity of considering full matrix elements with alloff-shell effects and interferences for multi-particle final states insupersymmetric models and give a status report on ongoing projects forsimulations of SUSY processes at the LHC with these codes, including all of theabovementioned corrections.
