Snelder, M. (author), Smit, S. (author), Schadd, M. (author), Walraven, E. (author)Network design problems such as the optimization of road capacities, public transport lines and frequencies, mobility hub locations, shared mobility services and traffic signal settings have been extensively studied in literature using sequential bi-level optimization. However, due to the computational burden, the design and response spaces that...conference paper 2023

Mehrabani, B.B. (author), Erdmann, J. (author), Sgambi, L. (author), Snelder, M. (author)User equilibrium (UE) and system optimal (SO) are among the essential principles for solving the traffic assignment problem. Many studies have been performed on solving the UE and SO traffic assignment problem; however, the majority of them are either static (which can lead to inaccurate predictions due to long aggregation intervals) or...conference paper 2022

Zou, H. (author), Dorsman, J.L. (author), Mandjes, M. (author), Snelder, M. (author)Activity-based travel demand modeling (ABM) provides a very high level of detail when modeling complex travel behavior of individuals. Since stochastic simulation is used, however, the high level of detail may induce a large random fluctuation in the output, necessitating (possibly) excessively many model reruns to produce reliable output. This...conference paper 2022

(author), Yorke-Smith, N. (author)Logistics planning is a complex optimization problem involving multiple decision makers. Automated scheduling systems offer support to human planners; however state-of-the-art approaches often employ a centralized control paradigm. While these approaches have shown great value, their application is hindered in dynamic settings with no central...conference paper 2022

Dekker, R. (author), Walters, C.L. (author)Localized buckles can occur in crashes when compressive stresses are dominant. However, due to their local appearance, they might be overlooked by a finite element analysis, meaning that local failure due to buckling will not be predicted. This could, for example, be catastrophic in the case of the crushing of a fuel tank or the impact on a ship...conference paper 2016
