What is complex systems modeling?

Complex systems modeling is the process of using mathematical, computational, or conceptual models to understand and predict the behavior of systems with many interconnected parts. These systems often exhibit emergent properties, meaning the whole system behaves in ways not obvious from its individual components. Examples include climate systems, ecosystems, social networks, and economic markets. By modeling these systems, researchers and analysts can explore scenarios, identify patterns, and inform decision-making in fields ranging from engineering to public policy.
