Summary
With conventional simulations (e.g. using the well-known simulation languages SIMSCRIPT or DYNAMO) coefficients of difference equations must be calculated by means of common statistical procedures implying a reduction of the amount of information. A certain loss of information is generally accepted. The MAPLIS language provides one- or multidimensional matrices (tabulations) instead of scalar coefficients. No reduction of information is required since the results of cross tabulations can be used immediately. Furthermore, a model designer may decide how many dimensions he needs. Some examples taken from the system of models as being used in the so-called “Münchener Simulationsmodell” (microdemographic prognosis) show the characteristics of the MAPLIS language: in form: how the various models and variables can be declared; how relationships between variables and between models are established. In content: how correct designing and programming of models is supported by a compatibility check of variables acting to each other; how dialogue with the computer enables the user to maintain, run and control models, to simulate exogeneous events by means of modification, which is not restricted to data: existing models can also be replaced during the run and new ones may be added.
