• Abstract

  Most facility location problems assume the static demands like the population and express the demands to a target network. In the case of the electric vehicle (EV) charging facilities assuming the vehicles as the demands, it is realistic to express the demands as the traffic flow to a target network. The facility location problem dealing with these demands is proposed as the  flow-capturing location-allocation model (FCLM)" by Hodgson et al.. However, since the EV has the constraint that the driving distance is short, it is difficult to straightforwardly apply the FCLM assuming the gasoline-powered vehicle as the demands to the EV charging facility. In this paper, we propose a modifying model of the FCLM which takes into the consideration of the constraint of the EV. We also confirm the usefulness of modifying model by using the data of road network of Bangkok, Thailand. From comparing between the FCLM and our model by using several evaluation indices, we conclude that our modifying model can efficiently locate facilities to a road network in the case of targeting vehicle (EV) that has the short driving distance.
