Vor dem Hintergrund des Verbundprojekts MAEKAS zur Förderung kooperativer Schienengütertransportedurch kleine und mittelgroße Unternehmen ist es von großem Interesse, die Effekte einerkooperativen Transportabwicklung im Schienengüterverkehr mithilfe von theoretischen Modellenzu messen, zu...

Transport optimization for rail transports and especially rail operator co-operations are an inter-esting modeling environment due to three specific characteristics: First a simple minimum optimi-zation direction of e.g. transport distances may not be feasible due to connecting transport routes...

The ‘backhaul problem’ is characterized by an imbalance in transport flows between locations. This problem is usually studied in a perfectly competitive framework, which essentially predicts that when the imbalance is sufficiently large, the freight price of transport from low demand regions...

Intermodal rail/road freight transport constitutes an alternative to long-haul road transport for the distribution of large volumes of goods. The paper introduces the intermodal transportation problem for the tactical planning of mode and service selection. In rail mode, shippers either book...

This paper shows that cycling of the simplex method for the m×n Transportation Problemwhere k-1 zero basic variables are leaving and reentering the basis does not occur once it doesnot occur in the k×k Assignment Problem. A method to disprove cycling for a particular k isapplied for k=2,3,34,5...
