Abstract: A method and system for ordering treatment or transport of victims of a mass casualty incident, prior to the incident, by establishing simulated casualty severity scores for each of the victims and considering the casualty severity scores and simulated resource availability. The order of treatment is provided on a card, chart, table or graph. Ordering treatment occurs through an analysis of triage simulations using analytical or mathematical programming techniques considering the severity scores, time periods of treatment delay resulting from constrained resources, estimated survival probabilities, and/or deterioration rates applied to the severity scores due to treatment delay.
