An emergency medical system simulation model

This paper presents a SIMSCRIPT simulation model designed for general use by health systems planners in evaluating existing or proposed emergency medical systems. An extensive validation of the model was performed using actual data from the San Fernando Valley area of Los Angeles. Appropriate operating procedures for use of the model are discussed. In conclusion, an application of the model in determining the desired number of ambulances for a system illustrates its usefulness in planning emergency medical systems.
