Multiobjective optimal route finding for ambulances using the genetic algorithm to minimize transport duration and blood pressure variation of a patient

This paper considers optimal transport routes of ambulances which minimize the transport duration to a hospital and the blood pressure variation induced by acceleration-deceleration of the ambulance and the slope of a road. For the road map given in the form of a graph, the optimal routes are searched by the multiobjective genetic algorithm so that the transport duration and the cumulative sum of the blood pressure variation are minimized in the sense of Pareto optimality.
