Computer-aided generation of chemical engineering process models. The availability of adequate process models is still the most striking bottleneck for routine application of model-based techniques in process design and operation. The development of knowledge-based software tools to support process modeling is considered an important contribution to a solution of this problem. After a brief summary of the modeling tools offered in current simulator architectures, a future knowledge-based modeling tool is sketched. In addition to the software engineering, the acquisition and formalization of the modeling knowledge – comprising meaningful submodels and generic modeling strategies – is essential for the feasibility of the approach and for the acceptance of a tool. Therefore, these two themes are discussed in considerable detail. Finally, first prototype developments towards a knowledge-based modeling tool are presented.
