In this thesis, ACSIM 2, the much-improved new version of the simulation language ACSIM, is being reported. ACSIM 2 has some characteristics which can not be shown in classical activity cycle diagrams, but which are indispensable for simulation studies. Creating and discarding entities, choosing different paths depending on various conditions, collecting consecutive activities within a single activity, are some of these features. Program and data has been separated and it has been made possible to save the final state of the system, thus continuing the simulation from the same state. It is also possible to give any initial state to the program, thus the possibility of different scenarios. One other novelty is a display facility which renders it possible to follow the simulation on the screen and interfere with it if necessary.
