Simulation and System Dynamics Models for Transportation of Patients Following a Disaster

This paper describes the simulation modeling for planning for the efficient transportation of patients following a disaster. Research was performed in an effort to predict the consequences of conceivable scenarios. Discrete-event simulation modeling provided an effective supplement to regular drill procedures when training emergency medical services personnel. Initial performance of the redesigned facilities was positive; however, dynamic feedback within the system of emergency medical services eventually resulted in unanticipated performance problems. System dynamics models were developed to help predict these implementation problems and suggest some ways to improve results.
