E-mobility, in particular electric vehicles (EVs), play a crucial role in the energy transition. While businesses are increasingly adopting EVs, there is still a lot of opportunity to grow. One aspect of this growth is the way these vehicles are used by companies, especially when it comes to the logistics of EV charging. To encourage companies...

This research addresses the operational challenges faced by the Sophia Children’s Hospital through a comprehensive analysis of its current state, literature review, and mathematical modeling. A model is created that produces a master surgery schedule, allowing for the allocation of patients to specific specialties, operating rooms, and days. Our...

Access to healthcare is a requirement for human well-being that is partly dependent upon safe infrastructure. One of the UN Sustainable Development Goals regarding healthcare is to achieve universal healthcare coverage, which includes access to qual- ity essential health-care services. In many developing nations, roads are often vulner- able to...

Large fault­tolerant universal gate quantum computers will provide a major speed­up to a variety of common computational problems. While such computers are years away, we currently have noisy intermediate­scale quantum (NISQ) computers at our disposal. In this project we present two quantum machine learning approaches that can be used to find...

The construction of cyclic railway timetables is an important task for Netherlands Railways (NS).This construction can be formulated as a Periodic Event Scheduling Problem (PESP). The most powerful technique for solving cyclic railway timetabling problems is constraint programming, especially via SAT solvers when PESP instances are encoded as...

In this thesis we look at three different algorithms within the field of phylogenetics and create a proof of concept for using machine learning to improve the algorithms. The problems are the maximum agreement forest problem, the hybridization number problem and finally the tail move problem. A study of the problems show that they can all...

This research is focused on the proactive-reactive rescheduling process of the Train Unit Shunting Problem (TUSP) on train maintenance shunting yards. An important difference between a scheduling process and the rescheduling process is that a reschedule must be both feasible and desirable (similar to pre-schedule), while a schedule does not...

In line with the growing trend of using machine learning to improve solving of combinatorial optimisation problems, one promising idea is to improve node selection within a mixed integer programming branch-and-bound tree by using a learned policy. In contrast to previous work using imitation learning, our policy is focused on learning which of a...

Storage systems, such as Flash memories, suffer, apart from the always present<br/>noise, also from offset. The presence of this noise can decrease the performance<br/>of a decoder using the Euclidean distance significantly. To negate the effects of<br/>offset, a new distance, the modied Euclidean distance, was introduced, which<br/>offers...

Recent work has shown potential in using Mixed Integer Programming (MIP) solvers to optimize certain aspects of neural networks (NN). However little research has gone into training NNs with MIP solvers. State of the art methods to train NNs are typically gradient-based and require significant amounts of data, computation on GPUs and extensive...

Let G=(V,E) be a connected undirected graph, where every edge has two weights assigned to it. This thesis considers the partitioning of the edge set E of G into subsets with three objectives in mind: i) balance the total amount of the first weight among the subsets, ii) balance the total amount of the second weight among the subsets and iii)...

Logistics service providers (LSPs) offering container transport to the hinterland of the Netherlands face the challenge of efficiently using the capacity of the barge in order to minimize cost, while part of the relevant information is still lacking at the moment decisions have to be made. The existing infrastructure and the transportation...

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...

We have tried to create a bin-packing algorithm that assigns items from a customer-order to totes such that the amount of totes is minimized. Analyzing the bin-packing algorithm that was used before this thesis had been written, taught us that xxx.xx% of the customer-orders was packed non optimal. In this thesis four algorithms are applied to...

Global medical use of azole antifungals and echinocandins has led to an enormous increase in resistant <i>Candida</i> species, that are most commonly associated with fungal infections. A possible mechanism causing resistance are single or simultaneous point mutations in the genes responsible for encoding antifungal target enzymes. The aim of...

In intermodal transport multiple types of vehicles are used to transport containers. If the routes of the vehicles are known, then the container allocation can be optimized. This problem can be modelled as an integral multi-commodity min cost flow problem on a time-space graph. This model has an arc-based and path-based form. In this thesis, the...

The companies CQM and EVO-it work together to help many different companies with solving their vehicle routing problems. EVO-it provides the interface of the software that the companies can use for route planning and CQM provides the technology that is used to solve the route planning problems, which concerns a lot of mathematical programming....

Synchromodal freight transport is introduced as intermodal transport, so container transport that uses several transportation vehicles, with an increased focus on a-modal booking, cooperation and real-time flexibility.<br/><br/>It is confirmed that general synchromodal network planning methods are rare or non-existent at the operational level....
