PROTOTYPE OF A KNOWLEDGE-BASED PROGRAM SY STEM FOR SYSTEM SIMULATION

Prototype of a Knowledge-Based Program System for System Simulation. T he present article describes a new approach for merging numeric simula tion techniques and knowledge-based methods for process simulation. In a first step the potential of such a combined technology is outlined, concerning both knowledge-based user support in handling and applicat ion of simulation codes as well as the support of the engineering task for chemical process development. An analysis of implementation techn iques outlines, how an adequate integration of numeric and knowledge-b ased software modules can be achieved by adoption of the object orient ed programming paradigm. The resulting requirements for the modelling of knowledge and the corresponding inference mechanisms are explained and a software prototype is presented by which this knowledge-based si mulation technology is currently being evaluated and refined using a c ase study from aerospace domain.
