The use of simulation in validating a multiobjective EMS location model

A location model is proposed for emergency medical service systems to solve the multiobjective location problem of minimizing mean response time and balancing facility workload. Location solutions generated from the model are tested with simulation and are shown to be quite realistic with regard to mean response time prediction and facility allocation. This efficiency is determined to be directly attributable to workload constraints.
