Click & Ride

Network operators in the rail sector offer customers the opportunity to receive individual connections for freight transportation. A request consists of origin, destination, departure or arrival time, and characteristics of the train (e.g. length, maximum speed, braking power). A customer should receive several different offers for one request. This project is about developing efficient algorithms for computing and selecting these offers.

Background

Various restrictions must be taken into account when calculating the offers. There are, for instance, capacity restrictions regarding system train paths or storage capacity at transshipment nodes. Moreover, the characteristics of the train also play an important role. In addition to the large amount of data, there are two other fundamental difficulties: real-time requirements and decisions based on incomplete data. On the one hand, these difficulties arise from the fact that the customer should receive the offers in guaranteed time. On the other hand, every request has to be processed without knowing the following requests.
