Abstract: A system for conducting simulations of disaster and hazardous incident responses to assist in the organization, planning, and testing of the response of healthcare and other institutions to such incidents. A series of modules are used to enter personnel resource information into the system, design and create disaster and hazardous incident scenarios, assign personnel to incident command system (ICS) roles, and conduct a simulation with said personnel taking appropriate responsive actions. Personnel may interface with the system through a program creating a dashboard interface. Personnel can access an ICS organization chart, and use it to initiate messages and communications, conduct meetings, take actions, and assign subordinate positions. Personnel can view the status of the response actions in real-time. Standard and custom reports can be created and viewed. The system also can be used to respond to a real incident using the same interface and methods practiced in the simulation.
