Conditional Modeling in an Equation-Based Environment

We identify the modeling capabilities needed for the efficient representation of conditional models in an equation-based environment and describe modeling tools for the performance of each of these tasks: conditional configuration of a model structure, conditional compilation and conditional execution of procedural statements. We also describe the details of the computer implementation of these tools and show how the expressiveness of an equation-based modeling language increases with their incorporation. Several chemical engineering examples are presented to demonstrate the scope of application of the proposed extensions.
