Parametric Models

Definition

Parametric models are mathematical representations of systems that use parameters to define relationships and constraints within the system. These models enable engineers and analysts to capture the behavior and performance of a system based on varying input values, facilitating the integration and compatibility analysis of different system components. By utilizing parameters, one can systematically explore how changes affect system performance and identify optimal configurations during integration efforts.
