Fire management inherently involves the assessment and management of risk, and decision making under uncertainty. Although organizational standards and guides are an important determinant of how decision problems are structured and framed, decision makers may view risk-based decisions from a perspective that is unique to their background and experience. Previous research has shown that individual differences in risk attitudes of fire managers exert a significant effect on fire management practices. Within the USDA Forest Service, Extended Attack (EA) incidents are those not contained within the first burning period after ignition. Simulation-based methodologies offer a potentially viable approach for improving our understanding of the role that risk attitudes and problem framing play in determining key decisions associated with EA incidents, and particularly on the decision to disengage, reengage after disengagement, and transitioning to a higher level of incident command. Scenario-based exercises in which Type 3 Incident Commanders respond to simulated incident conditions provide an opportunity to study decision behavior based on current theories and models of decision making that point to the role of problem framing and incentive structures as key decision drivers.
