Incident Command System provides a framework for commanders to manage an incident. However, maintaining good situation awareness in an emergency situation is often challenging to the Incident Commander. Stress may result in task fixation which may cause the commander to miss critical information and can eventually lead to poor decisions. The proposed augmented decision support system, with an integrated knowledge base, enhances the commander's decision making and situation awareness by presenting the information that may have been missed. The system has been evaluated to investigate its utility in chemical hazard scenarios. The system was used by experienced Incident Commanders to perform a risk analysis on a hypothetical situation. Results indicate that the information presented by the decision support system significantly improved commander's decision making. The tool can be applied to other domains that face challenges in making effective decisions, particularly in time-critical environments such as clinical decision making.
