Structural modeling is a research area that involves creating mathematical models to represent and analyze the structure and behavior of complex systems or entities. This can include physical structures like buildings or bridges, as well as abstract systems like organizations or biological networks. By using structural modeling techniques, researchers can understand how different components within a system interact with each other, predict potential outcomes, and identify areas for improvement or optimization. Structural modeling is often used in fields such as engineering, physics, biology, and social sciences to study complex systems and make informed decisions based on the model's predictions and insights.
