An optimization and simulation approach to emergency stations relocation

This paper suggests and compares three median-type location models to determine how to optimally relocate existing emergency medical stations. It also describes a detailed computer simulation model used to evaluate the locations proposed by each model in terms of several indicators of system performance. The simulation model was calibrated using real data from a health care provider in the Slovak Republic. The results of the computer simulation experiments suggest that the simple p-median model can significantly improve the accessibility of urgent health care to patients.
