MIHEA in Action: A Reproduction Study and Evaluation on Learning Bayesian Networks from Data

Mixed-integer optimization problems, incorporating both discrete and continuous variables, present unique challenges across various domains such as computer science, finance, logistics, and healthcare. Evolutionary Algorithms (EAs) have emerged as powerful optimization techniques capable of tackling such complex problems in either the discrete...

Towards a Sustainable and Liveable Desakota: Designing for sustainable industry transition in the peri-urban territory of the Greater Bay Area

This thesis explores spatial strategies for achieving sustainable industry transition in the dispersed urbanised areas of the Greater Bay Area (GBA) in China. Since 1978, urbanisation in the GBA has accelerated, significantly expanding beyond metropolitan regions. These dispersed areas, described as the Desakota by Terry McGee, encompass a...

Network dynamics and its impact on innovation outcomes: R&D consortia in the Dutch water sector

In this study, we explore the relationship between inter-organizational network dynamics and innovation outcomes. We focus on node turnover and argue that both cluster and broker dynamics can range from low (stable) to high (volatile), resulting in differentiated outcomes. The data comprises 318 consortium members participating in 104 R&D...

A topological characterisation of looped drainage networks

Hydrodynamic models are used to analyse water networks (water distribution, drainage, surface water, district heating, etc.). The non-linear nature of water flows necessitates the use of iterative solution methods in hydraulic modelling. This requires a relatively large computational effort. To reduce this effort, networks, network forcing...

Multi-modal network evolution in polycentric regions

The development of public transport networks in polycentric regions involves making complex trade-offs between extending network coverage, densifying local connections, offering improved connections between urban centers and increasing capacity on existing links. Moreover, different modalities might be suitable for each of these development...

Metropolitan rail network robustness

In large-scale urban agglomerations, heavy rail in the form of metro and commuter train serves as the backbone of the metropolitan public transport network. The objective of this paper is to investigate whether networks with strikingly different structure and development pattern exhibit different robustness properties in the event of random...

Modelling growth principles of metropolitan public transport networks

The development of metropolitan public transport networks often involves choosing between investing in extending radial lines or constructing ring connections. While the former enlarges network coverage the latter enhances network connectivity and reduces the need to perform detours. Moreover, investments might be better directed at...

Modelling citation performance of Canadian researchers using Bayesian Networks

This thesis is about modelling citation performance using Bayesian networks (BN). As an approximation for citation performance, we will use the proportion of papers by an author that resulted in being one of the top 10% most cited papers. Using 15 predicting variables such as year of first publication and average number of authors per paper, we...

A Simple Representation of a Complex Urban Transport System Based on the Analysis of Transport Demand: The Case of Region Ile-de-France

In densely urbanised areas the structure of the transport systems becomes quite complicated. Many types of transportservices are available and many types of modes are being used, thus offering a wide palette of transport options. How do all these transport services and modes relate to each other? In practice it proves to be quite hard to define...

The Effect of Network Structure and Signal Settings on the Macroscopic Fundamental Diagram

Recently it has been proposed that the performance of a complete network can be represented graphically using only aggregated data for flow and density. The resulting graph is the macroscopic fundamental diagram (MFD), which relates the average flow (performance) to the number of vehicles in the network (accumulation). The resulting shape is...

Reconfiguring supply chains over the product life cycle: An exploratory study

Product lifecycles are becoming increasingly short in several industries. This has implications on the way companies are able to organize and adapt their operations. This thesis explores how supply chains can be reconfigured to adapt to such changes over the product life cycle. The main research questions are defined as: 1. What are the...
