A FORMAL REPRESENTATION OF PROCESS MODEL-EQUATIONS

The lack of adequate support for the development of mathematical proce ss models confines the application of model-based techniques in the de sign and operation of complex chemical processes. To overcome this pro blem considerable effort has to be put in the development of knowledge -based software tools. The development of such tools requires a proper structuring of process models followed by a formalization of their re presentation. In this contribution, elementary modeling objects for th e representation of the behavioral aspects of chemical processes are d efined. The introduced methodology and its formalization in terms of t he object-oriented data model VEDA allows the representation of the mi xed types of equations and formalisms arising in mathematical process models. It provides generality and extensibility since new types of eq uations or formalisms can be incorporated easily.
