den Bakker, Yvonne (author)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...master thesis 2024

Beeravelli, Arun Datta (author)The Global Shipping industry is responsible for transporting 90% of global commerce and is responsible for 3% of global greenhouse gas (GHG) emissions. Addressing this, the International Maritime Organization (IMO) aims to reduce GHG emissions from international shipping by 40% by 2030 and achieve net zero by 2050. This study explores Low...master thesis 2024

Skoulas, Vasileios (author)Long truck queues and congestion around terminals is a common sight, however they come with many negative externalities for all the stakeholders involved. Truck Appointment System (TAS) is the most commonly used system to face these problems, but it still has some drawbacks and limitations. Consequently, in this research an extension of the...master thesis 2024

Hyde, Edward (author)As the aviation industry has agreed on the goal of achieving net-zero CO2 emissions by 2050, various mitigation strategies are being deployed and developed. This paper focuses on reducing emissions at airports by towing aircraft instead of taxiing with their main engines; dispatch towing. This is done by developing a model to optimise the...master thesis 2024

Arnoldus, Matthijs (author)Computational efficiency is essential for large-scale mathematical optimisation problems, such as the generation expansion planning problem, to be practically applicable. In linear programming solvers, crossover is frequently a bottleneck when solving optimisation problems. This study aims at determining why crossover is a bottleneck in solving...master thesis 2024

Hypothesis Testing in Contingency Tables: A Discussion, and Exact Unconditional Tests for r×c TablesKeer, Pim (author)Every time one counts the number of occurrences of a pair of values for two categorical variables, one obtains a contingency table. These tables are one of the simplest representations of data in order to statistically test for the presence of some association between the two variables under consideration. Although naturally occurring in so many...master thesis 2023

Zwep, Louise (author)The increasing popularity of e-commerce has led to a greater emphasis on improving parcel delivery processes. Among the various stages of the delivery process, packing parcels into delivery vans affects the delivery time. The efficiency of delivery is optimized when each parcel is conveniently accessible upon arrival, thereby minimizing the...master thesis 2023

Endlich, Luuk (author)The design of a guide-path map is a well-known problem in various industries, such as automated guided vehicle (AGV) systems, road networks, and train track design. Nowadays, designing a path map is a manual, time-consuming, and expensive process. The solutions often turn out to be far from optimal. Several approaches are known to generate path...master thesis 2022

Segeren, Megan (author)In this paper, the emissions mitigation potential of implementing operational towing at major European airports is evaluated. Using mixed-integer linear programming, a scenario simulating mixed taxiing operations is used to find the relationship between fixed vehicle costs and target emission savings at an airport and European level. Using...master thesis 2022

Smeets, Lucy (author)Sorting systems form an example of event driven systems. These types of systems are referred to as discrete event systems (DES), and they consist of jobs that need to be performed at available resources. In an autonomous sorting system, jobs consist of robots receiving and delivering parcels at the correct locations. With scheduling, optimal...master thesis 2022
