Automated vehicles have the potential to create a future in which most cars are shared instead of being individually owned and used. The advantages of vehicle sharing are expected to be multiple: reduced traffic, freed-up parking space, safer trips and a lower environmental impact of traveling. The dial-a-ride problem with transfers (DARP-T)...

A Taxi Dispatch Problem involves assigning taxis to requests of passengers who are waiting at different locations for a trip. In today's economy and society, the Taxi Dispatch Problem and other transport problems can be found everywhere. Not only in transporting people, but also in food delivery from restaurants and package delivery for all kind...

In a Vehicle Routing Problem with Time Windows (VRPTW), orders have to be picked up and delivered within certain time windows. In practice, planners often allow violations of these time windows, when the solutions with violations have better objective values. This is done by changing the problem into a Vehicle Routing Problem with Soft Time...

In this thesis, we investigate whether maximizing the coverage of taxis can be beneficial when the goal is to minimize the waiting times of the clients. When dispatching taxis, often only current requests are taken into account and not future ones. We examined how beneficial it can be to take coverage into account. For taxi companies it is...

In this thesis we investigate an extension of the famous Nurse Rostering Problem. The Nurse Rostering Problem is the problem of finding an optimal assignment of nurses to shifts given some constraints. We extend the problem by considering that the nurses different sets of skills by which they can only perform certain tasks. We want the working...

The current sourcing strategy of a company which relies on the backhauls of third party logistic providers for transportation currently does not take the availability of backhauls into account. Therefore, there is uncertainty in the number of trucks that are available for transporting freight from a supplier to a customer. This uncertainty can...

This thesis focuses on optimising the Emergency Medical Services (EMS) in the Netherlands. In the current situation, the Netherlands is divided into 24 independent regions in which ambulances operate. These regions can be merged in order to reduce response time and increase efficiency. Different models are presented in which these regions are...

In this thesis, we propose two mixed integer linear program formulations for an optimization problem that incorporates annualized hours: an exact one and an approximation. The objective of our model consists of three weighted parts: a part which minimizes the difference between working hours and contract hours for each employee per week, a part...

De locaties van ambulancestations zijn van belang bij het redden van levens. Dit onderzoek beschrijft een Mixed Integer Lineair Programming (MILP) model die de optimale locaties van ambulances bepaald zodat het dekkingsniveau maximaal is. Het dekkingsniveau is het percentage van het totale aantal oproepen waarbij een ambulance binnen een...

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...

In this thesis, we analyse the optimisation of an annualised hours problem. Annualised hours problems are a widely studied subjects, in which the working hours for a given number of employees per week are minimised. We approach this problem with a mixed integer linear program, where the objective function of this problem is divided into two...

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...

Hospitals need to be staffed around the clock to ensure satisfactory care for all patients. To this end, a set of shifts is defined which are assigned to nurses in a work schedule. The nurse rerostering problem (NRRP) occurs when due to unforeseen circumstances some shifts become unassigned: one or more nurses are no longer able to work some of...

In this thesis, we consider levelling the number of required beds at the holding and recovery department. Due to the decreased number of available nurses, the workload for the nurses at hospitals has increased. For this reason, it is important to level the number of required beds at the holding and recovery department. By doing so, the workload...
