A Mathematical Model for the Location of Charging Station for Electric Buses

Abstract

In order to create sustainable solutions, the use of electric vehicles instead of traditional vehicles, which is called fossil fuel vehicles, is significant. It is essential to determine the locations of the charging stations to be established so that electric vehicles can be preferred in intercity buses, which are frequently used in the transportation network. For the selection of locations of the charging stations, there are limitations such as waiting times at the charging stations, having sufficient charge for the next stop, and especially the budget. In addition, determining the candidate charging stations among the existing bus stops would increase customer satisfaction as it would prevent extra breaks. However, it may not be possible to use electric buses on every bus route due to both driving range and budget constraints. For this reason, in this paper, a multi-objective mathematical model that minimizes the number of charging stations and maximizes the number of electric buses is proposed and the weighted sum method is used to solve this model. In addition, the proposed mathematical model was solved using the General Algebraic Modeling System (GAMS) with the data of a bus company in Türkiye.
