Emergency medical service (EMS) providers are charged with the task of managing ambulances so that the time required to respond to emergency calls is minimized. One approach that may assist in reducing response times is ambulance redeployment, i.e., repositioning idle ambulances in real time. We formulate a simulation model of EMS operations to evaluate the performance of a given allocation policy...
This paper generalizes the cross-entropy (CE) method to a population-based setting, where a population of probabilistic models is maintained/updated and subsequently propagated from generation to generation. One of the key questions in the proposed approach is how to efficiently distribute a given sample budget among different models in a population to maximize algorithm performance. We formulate...
