A liner shipping network design problem is considered which includes ship scheduling and cargo routing decisions. The question is how to enable loose cooperation of multiple liner shippers for jointly solving this profit maximizing network design problem. A variable neighborhood search...

Hubs are centers for collection, rearrangement,and redistribution of commodities in transportation networks. In this paper, non-linear multi-objective formulations for single and multiple allocation hub maximal covering problems as well as the linearized versions are proposed. The formulations...

We study minimum integer representations of weighted games, i.e. representations where the weights are integers and every other integer representation is at least as large in each component. Those minimum integer representations, if the exist at all, are linked with some solution concepts in...
