In the course of climate change and the proceeding rejection of fossil energy sources towards renewable energies the importance of alternative engines in the transport sector has increased strongly. Electro mobility occupies a special position in the scope of alternative engines because electric vehicles enable an emission-free movement.

For transportation companies there arise new challenges concerning the entrepreneurial planning and controlling processes when deploying electric vehicles. The much lower range of the electric vehicles compared to combustion engine vehicles and the possibility to recharge the battery at some particular charging stations, play an important role.  The planning step within the planning process of transportation companies which is particularly affected by the additional restrictions is the resource resp. vehicle scheduling step which determines the deployment of vehicles for serving the offered service trips. Different battery types and charging technologies at charging stations play an important role in this planning step, as these factors have a direct impact on the travelling range and the recharging time.

The technical infrastructure - i.e. the location of charging stations and their implemented charging technology within the route network - represents another important cost factor. The infrastructure must be taken into account, since it determines both, the distance of vehicles to potential charging stations and their charging time.

Within the project "E-Mobility in Public Transport" new models will be developed to solve the vehicle scheduling problem considering electromobility both exactly and heuristically. Therefor latest research in the battery and charging technology as well as the technical infrastructure shall be incorporated.
