Simulation; object-oriented programming; non-standard simulation studies; SIMULA

The modern simulation applications, namely those to intelligent system with sophisticated control techniques based on complex computer models, need communication among simulation models existing contemporarily. SIMULA offers a standard class SIMULATION for simulation but nowadays it makes problems because it does not allow giving names to simulation models. Therefore we decided to construct another class, similar as much as possible to SIMULATION but allowing identifying models. The new class is called SIMULAT. The paper contains its description and a discussion on the reasons for differences between both classes.
