Sometimes a complex combinatorial problem has easily identifiable subproblems for which methods are available. Often, strong interactions between these subproblems prevent us to use these methods in a straightforward way. In railway industry, finding a schedule for train service and shunting tasks is an example of such a problem with clearly...

The recently introduced Gene-pool Optimal Mixing Evolutionary Algorithm (GOMEA) for discrete variables has been shown to be able to efficiently and effectively exploit the decomposability of optimization problems, especially in a grey-box setting, in which a solution can be efficiently updated after a modification of a subset of its variables....

Nowadays the airline industry is an important factor in our economy. In this changing market it is important to keep up to date with the latest developments. Especially cost savings, and cost reductions form a vital component to stay competitive in the airline industry. For this work the deicing procedure is studied, which is part of the ground...

The recently introduced Linkage Tree Genetic Algorithm (LTGA) has shown to exhibit excellent scalability on a variety of optimization problems. LTGA employs Linkage Trees (LTs) to identify and exploit linkage information between problem variables. In this work we present two parallel implementations of LTGA that enable us to leverage the...

Congestion on the road is a widely recognized problem. To improve traffic conditions on the road, several methods have been developed over the years. Dynamic traffic management is one of them and has proven to be effective. It aims at making better use of the existing network capacity and at managing traffic flows. In order to further improve...

Robustness is essential for schedules if they are being executed under uncertain conditions. In this thesis we research robustness in Partial Order Schedules, which represent sets of solutions for instances of the Resource-Constrained Project Scheduling Problem. They can be generated using a greedy procedure called Chaining, which can be easily...

We study the single machine version of the task scheduling problem with release times and deadlines. This problem is too simple to be of practical importance in itself, but it is also used as a relaxation in algorithms for the Job Shop scheduling problem, which is a more practical task scheduling problem. We study exact algorithms for solving...

Het bedrijf NedTrain beschikt over software om roosterproblemen op te lossen. De wens van NedTrain en het doel van dit project is om deze software uit te breiden met de functionaliteit om flexibele schema's te berekenen. Deze roosterproblemen hebben te maken met het probleem dat ook wel bekend staat als het Resource Constrained Project...

Report about the 11 weeks period of the Bachelors Project done for the 'Twin Hub Network Project'. Goal of the Project was to create a application that shows different train/truck network using a 'Hub' in a graph form. This application uses a Twin Hub Bundling Algorithm written by Sebastiaan Meijer for his Masters Thesis.

We study the application of stochastic scheduling methods for dealing with the negative impact of uncertainty on the timely delivery of NedTrain maintenance projects. A stochastic scheduling problem includes a quantification of uncertainty by representing the duration of a maintenance activity with a probability distribution. The solution is no...

Optimisation of transport networks can yield substantial reductions in transport costs and improve the quality of service for the users of these networks. When optimising intermodal rail-road networks, organising large transport volumes on transport links is key for bringing down the costs per container-kilometre. By bundling container flows in...

This thesis focuses on the properties of (multi-agent) task scheduling instances represented as Simple Temporal Problems (STP). By defining a subclass STP$_{\prec}$ of STPs that contain these task scheduling instances, existing algorithms for arbitrary STPs can be improved if applied to task scheduling STPs, allowing arbitrary schedules and...

In this thesis we will develop algorithms for the scheduling of train maintenance at NedTrain facilities. We present a detailed analysis of the maintenance process at NedTrain. The problem of scheduling train maintenance is formalized and expressed using linear inequalities. We show that the Simple Temporal Problem can be used to find schedules...

BitTorrent has turned into the most popular P2P file sharing protocol and is used for various purposes such as Video on demand and Media Streaming. The fundamental problem with P2P networks in general is that quality of service highly depends on altruistic resource sharing by participating peers. Many peers freeride on the good intentions of...

One way to prevent collisions and deadlocks between agents on infrastructures with capacity constraints is to use context-aware route planning algorithms. In context-aware route planning, there is a set of agents each planning a conflict-free route from a start location to a destination location on a common infrastructure. If a sequential...

Autonomous, self-interested agents have to construct plans for their activities. Together, these plans form a joint plan in the multi-agent system the agents are part of. Merging the plans of these agents is not guaranteed to be successful as their plans might conflict. Hence, we require some form of coordination that enables agents to plan for...
