Agent-based modeling

Definition

Agent-based modeling is a computational method that simulates the interactions of autonomous agents to assess their effects on the system as a whole. This approach is particularly useful in scenario planning as it allows for the exploration of complex systems and dynamics by modeling individual behaviors and decision-making processes. By simulating diverse agents, it provides insights into how collective outcomes emerge from simple rules governing agent interactions.
