Solution methods for migrating fibre in current telecommunication networks

Almost one third of the Dutch population has a fibre optic connection, also called Fibre to the Home (FttH). Fibre is currently the fastest and most reliable Internet technology. It consists of strong and flexible wires that are able to transport light signals over long distances. With such fibre optic connections, information is transmitted...

Combinatorial optimisation methods for wind farm installation scheduling: Optimisation in crane actions and installation ship routing

The offshore wind industry is rapidly growing, and so is the competition in this market. Normally, offshore installation companies receive a subsidy for building offshore wind farms, but due to multiple companies bidding to install for lower and lower subsidies, the point where wind farms are installed without subsidy has been reached. Therefore...

Long-term multi-priority surgery scheduling: a case study for the gynecology department

Predicting motion sickness for crew transfer vessels using modelling and date mining techniques

In recent years, the offshore wind industry has grown significantly. The wind turbines are constructed in wind farms, and are serviced with relatively small crew transfer vessels. These vessels transport repair crews from the mainland to the farms and back within a day. One of the big challenges is that these transits can cause motion sickness....

Optimization of User Equilibrium container transportation problems using toll pricing

The goal of this thesis is to provide a method to obtain a User Equilibrium (UE) in a synchromodal transportation network in which we transport containers for multiple customers. <br/>We use the Space Time Network (STN), in which the travel time of modalities is fixed and independent of the occupancy of the network.<br/>We define the User...

Deep Neural Networks and Optimization: A promising tag team

Machine learning has been a computer sciences buzzword for years. The technology has a lot of potential and a huge number of applications that spoke to people with and without knowledge of computer sciences. Image, text and speech recognition, social profiling, computergames, everything seemed possible. Machine learning is not as much in the...
