Models, methods and experiments — A new structure for simulation systems

In 1968 the CSSL-standard for simulation languages was introduced determining the structure of simulation languages, too. In the following years Zeigler proposed new structures which became a quasi-standardization. In this contribution an extension of these structures is introduced: the concept of models, methods and experiments. This concept adds the level of “methods” to model level and experiment level. The advantage of this new concept is shown within the simulation system HYBSYS, which extensively uses this new structure. This concept allows also to introduce parallel concepts independent on actual models and to implement analytical and symbolic methods.
