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 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 report about a metaheuristic solving approach for a vehicle routing problem with a heterogeneous vehicle fleet. Customer locations require the visit of two different types of vehicles. Operation starting times at the customers are coupled by a specific time window constraint called implicit...

Many supply chains suffer from a lack of flexibility, adaptability, and robustness, which imposes customer dissatisfaction, transportation, backlog, and rework costs on companies. The mobile supply chain (MSC) is a newly developed idea that aims to rectify this problem. In this kind of supply...

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...

The present paper studies a generalization of the less-than-truckload pickup and delivery problem. The problem at hand arises in the hinterland of container terminal where empty and loaded containers have to be transported between a container depot and a set of customer locations. However,...

The mobile supply chain (MSC) is a new concept that allows companies more adaptability and flexibility. In MSCs, a product family can be produced, distributed, and delivered by a mobile factory, carried by trucks, and shared among different customers. In this paper, to optimize production...

When considering long-haul transport requests, the durations of rest periods and breaks highly influence the overall time needed for fulfillment. In the European Union, Regulation (EC) No 561/2006 defines the rules for the number, duration and time intervals when rest periods and breaks have to...

Fuel is one main cost driver in the road haulage sector. An analysis of diesel price variations across different European countries showed that a significant potential for cutting fuel expenditure can be found in international long-haul freight transportation. Here, truck drivers are often on...
