Titel: 2 Models for 1 stage carsharing Pricing and relocation problem


Abstract: We live in a world where transportation is a necessity. This has as effect an increase in usage and dependency of private cars, which contributes to pollution [2], traffic congestion etc. The measures, that have been taken to ease the traffic, did not gave the expected result [3, 4, 5, 2, 6, 7]. On the other hand carsharing has demonstrated that it represents a real solution to those problems [8, 9, 10, 11]. Several studies have shown, that carsharing is a viable and flexible alternative that increase mobility, reduce dependence of private vehicle ownership and energy consumption, lower GHG emission, and support active lifestyles by encouraging bicycle and pedestrian travel mode.
The history of carsharing has began with a cooperative named Sefage Selbstfahrer-gemeinschaft) in Zurich, Switzerland in 1948, which operated until 1998. The idea was to allow people, who could not afford to purchase a car, the possibility to share one. Services offered by CSO have evolved in time, nowadays offer being very flexible, adapted to the modern demand: on-demand, short-term, one-way usage [12] To respond to the demand in this way creates new challenges for the CSOs, as the place of the destination is not known in advance, neither the duration of the ride. Furthermore the one-way rides tend to create vehicles agglomeration in some places and shortage in other places [13, 14, 15, 16], which will generate low level of services. Therefore the relocation service is a important part of the modern carsharing planning. Research literature covers different aspects of the subject [16, 11, 17, 18, 19, 20, 21, 23] and studies are classified in survey [12] . We will address the one stage problem of simultaneously setting the price and deciding the relocation of the vehicles. 2 models are proposed for finding the solution, expanding the formulation provided by [1]. In 3 Chapter 2 we present the problem and two models to solve the problem. In Chapter 3 we present a small instance example. In chapter 4 we present a computational study and in Chapter 5 the conclusions.
