van Schilt, Isabelle M. (author), van Kalker, Jonna (author), Lefter, I. (author), Kwakkel, J.H. (author), Verbraeck, A. (author)Schedule design in the transportation and logistics sector is a widely studied problem. Transport service providers, such as the train industry and aviation, aim for schedules to be on-time according to the planning (i.e., on-time performance or OTP) in order to increase the service level by ensuring that passengers actually make their...journal article 2024

van Droffelaar, I.S. (author), Kwakkel, J.H. (author), Mense, Jelte P. (author), Verbraeck, A. (author)Simulation–optimization models are well-suited for real-time decision-support to the control room for search and interception of fugitives by Police on a road network, due to their ability to encode complex behavior while still optimizing the interception. The typical simulation–optimization configuration is simulation model optimization,...journal article 2024

van Schilt, Isabelle M. (author), Kwakkel, J.H. (author), Mense, Jelte P. (author), Verbraeck, A. (author)Supply chain visibility concerns the ability to track parts, components, or products in transit from supplier to customer. The data that organizations can obtain to establish or improve supply chain visibility is often sparse. This paper presents a classification of the dimensions of data sparseness and quantitatively explores the impact of...journal article 2024

Verbraeck, A. (author), Bosch-Rekveldt, M.G.C. (author), Rye, Sara (author), Simon, Peter (author)Project Risk Management helps with achieving project objectives, especially those concerning cost, time and quality. In the current APM definition, project risks are uncertain events or circumstances that may or may not happen. Risks are either threats that hurt the project objectives, or opportunities that are positive for the project...other 2023

Verkaik-Poelman, M.C. (author), Hegyi, A. (author), Verbraeck, A. (author), van Lint, J.W.C. (author)Model-based predictive signal control is a popular method to pro-actively control traffic and to reduce the effects of congestion in urban networks. In combination with structure-free controllers, which adapt signal settings in arbitrary order and combination (no imposed cycles), these predictive control methods have a high potential to...journal article 2023

Shishkov, B.B. (author), Fill, Hans Georg (author), Ivanova, Krassimira (author), van Sinderen, Marten (author), Verbraeck, A. (author)Enabling technologies concerning hardware, networking, and sensing have inspired the development of context-aware IT services. These adapt to the situation of the user, such that service provisioning is specific to his/her corresponding needs. We have seen successful applications of context-aware services in healthcare, well-being, and smart...conference paper 2023

Destyanto, A.R. (author), Huang, Yilin (author), Verbraeck, A. (author)The COVID-19 pandemic in Indonesia has led to a significant change in human mobility. It is also considered the most serious threat to the inter-island trade network since the economic crisis in 1998. Leveraging two-year historical port call data (covering 6,000 records in total) of Indonesian domestic cargo vessels from the Automatic...conference paper 2022

Huang, Yilin (author), Xie, Xu (author), Cho, Yubin (author), Verbraeck, A. (author)Data assimilation (DA) is a methodology widely used by different disciplines of science and engineering. It is typically applied to continuous systems with numerical models. The application of DA to discrete-event and discrete-time systems including agent-based models is relatively new. Because of its non-linearity and non-Gaussianity, the...journal article 2022

Akoluk, D. (author), Zatarain Salazar, J. (author), Verbraeck, A. (author)Justice in the climate context has gained more attention in the last decade. One of the main reasons is the increasingly pervasive and aggressive impact of climate change on societies and economies. Existing inequalities and disparities between sectors, regions, and generations are often exacerbated by proposed or applied policies. Hence,...abstract 2022

Shishkov, B.B. (author), Ivanova, Krassimira (author), Verbraeck, A. (author), van Sinderen, Marten (author)Drones performing an autonomous mission need to adapt to frequent changes in their environment. In other words, they have to be context-aware. Most current context-aware systems are designed to distinguish between situations that have been pre-defined in terms of anticipated situation types and corresponding desired behavior types. This only...conference paper 2022

(author)Tabletop games that require the aid of a human facilitator are typically designed for a physical environment. However, during the COVID-19 pandemic, lockdown measures prevented people from gathering. Therefore, tabletop games were sometimes played and facilitated in a mediated environment using online communication tools instead. But this...conference paper 2022
