In our paper, we analyze new exact approaches for the multi-mode resource-constrained project scheduling (MRCPSP) problem with the aim of makespan minimization. For the single-mode RCPSP (SRCPSP) recent exact algorithms combine a Branch and Bound algorithm with principles from Constraint...

We consider a novel generalization of the resource-constrained project scheduling problem (RCPSP). Unlike many established approaches for the RCPSP that aim to minimize the makespan of the project for given static capacity constraints, we consider the important real-life aspect that capacity...

Competition between two-sided platforms is shaped by the possibility of multihoming. If users on both sides singlehome, each platform provides users on either side exclusive access to its users on the other side. In contrast, if users on one side can multihome, platforms exert monopoly power on...

The first-in, first-out (FIFO) queue discipline respects the order of arrival but is not efficient when customers have heterogeneous waiting costs. Priority queues, in which customers with higher waiting costs are served before customers with lower waiting costs, are more efficient but usually...

Truck drayage in container ports faces several challenges. Due to the ongoing growth of container ship sizes, there are increasingly high peak situations in landside container handling at logistic nodes in the port, e.g. container terminals, empty depots, freight stations. In combination with...

This paper tries to reproduce a traffic supply curve using the method suggested by Walters (1961), but finds that the result is anything but positive. Instead, this paper proves that such curves belong to the road users in a negative relation. Traffic involves cost, and toll and congestion...

This working paper assesses cross-border economic integration in the Lower Congo region. It focuses on the Kinshasa-Brazzaville conurbation, which is projected to become Africa's largest urban area by 2025, and is already serving as the gateway to large hinterlands. Despite their size and...
