Model-embedded on-line problem solving environment for chemical engineering

The building of custom monitoring, control, simulation and diagnostics applications for complex chemical plants necessitates the integration of models into the problem solving process. This paper describes a system and its practical applications that supports this activity. It is based on the Multigraph Architecture, which is a generic framework for building these model-based systems. The paper discusses the modeling paradigms used, how the applications are generated, and some practical, existing applications.
