Development of Integrated Functional-Structural Models

Abstract Chemical processes are usually large complex systems. Models concerning the topology and structure have existed for decades and more recently functional models have appeared as a complementary way to describe these systems. In this paper a new modeling formalism to capture structure as well as functionality of a system is presented. Based on the visual formalism higraphs, it has been adapted and extended to be applicable to process systems description. Although it can be used for several applications, this paper focuses on its use in risk analysis.
