Modelle in einem einheitlichen Metamodell zu beschreiben. Da diese Tools ber dynamische Modellwelten arbeiten, wird von einer reduzierten Berechenbarkeit in solchen Modellen ausgegangen. Tools bilden dynamische Modellverwaltungssysteme. Solche Basissysteme sollten eine weitgehende Analyse der Taxonomie sowie eine Reklassifikation von Modellinstanzen unterst tzen. Some prototypical implementations make the concept clear.
Buildings are a special matter for design activities.
That is the reason why an analysis is necessary especially for the early design stages. The objective of that analysis is that CAD-tools for this design stage can be implemented. The starting point for the examination is the pragmatic process model on the one hand and the cognitive process model on the other hand. Starting with the thesis architectural design is a process to plan a building in advance with help of models, the object oriented modelling technology is thoroughly evaluated. The suitability of the method is generally proofed for the representation of buildings by analogical models.
