In a conventional dial-a-ride-system passengers are moved with the same vehicle between their pickup and their drop-off location. In a dial-a-ride-system with transfer, it is possible (or even standard) that passengers change the vehicle once or several times. Transfer Scheduling Constraints...

We investigate the simultaneous schedule determination of several leagues in a championship. Beside limited availability of venues, the substitution of players among teams of a club requires the consideration of mutual match slot exclusions associated with teams playing in different leagues...

We analyse the benefits and limitations of the integration of sourcing decisions into the operational route compilation task of a road-haulage company. A trucking company has to supply several customer sides. The demanded quantities are given. The trucking company has to decide which truck...

In this research we consider the problemof scheduling rounds of a non-professional table-tennisleague. We formalize the problem in terms of atimetabling optimization problem. Then we solve thishighly constrained problem with a permutation based GeneticAlgorithm for which feasibility preserving...

This article reports the development and the assessment of a freight rate optimization approach based on mathematical modeling and optimization. It exploits the functional interdependency between the price of a (service) product and the quantity of the product using this price. Solving the...
