This thesis concludes my research of the last four years at the Department of Oper-ations at the University of Groningen. The work has been financially supported by the Netherlands Organization for Scientific Research (NWO), and further financial support and practical validation of the conducted research were received from an extensive consortium including wind turbine manufacturer Siemens, offshore wind service providers Groningen Seaports, Van Oord, and Wijnne Barends Logistics, and other knowledge partners including ECN and DHL.
I want to thank my supervisors Ruud Teunter, Bram de Jonge, and Jasper Veldman who always made time for my unscheduled visits and without whom my thesis would not have reached its current level. Together they motivated and convinced me to aim to publish in top-rated journals but they also took the effort to discuss non-research related topics. In particular, I want to thank Ruud for his very quick, to-the-point, and useful feedback that surely improved the positioning of my research, Bram for his meticulous proofreading, and Jasper for our talks in which we kept a broader view on my PhD trajectory. Besides my supervisors, I also wish to express my gratitude towards the members of the reading committee, consisting of Philip Scarf, Geert-Jan van Houtum, and Iris Vis, for their time and effort to carefully assess this thesis.
My friends Albert Schrotenboer and pilot Dennis Prak certainly made my PhD journey very joyful. To both of you, thanks for sharing your down-to-earth views on everything and the memorable moments on the sixth floor, at conferences, and at home. Also an extensive group of fellow PhD candidates and colleagues at the department contributed to the good times I have had. To Albert, Dennis, cycling expert Bart Noort, Hendryk Dittfeld, sailor and musician Jan Eise Fokkema, Babette Huisman, MDP specialist Jos´e Alejandro Lopez Alvarez, Roel Post, Lisanne Hut-Mossel, Sabine Waschull, Aline Seepma, Robbert-Jan van der Burg, Bolor Jargalsaikhan, Gerlach van der Heide, Paul Buijs, Bram, Ward Romeijnders, and all other colleagues and PhD candidates that were present during the last four years: thanks for all the pleasant moments at work; I really enjoyed our lunch breaks that were usually immediately extended by not so short coffee breaks, our discussions on politically sensitive topics, our ‘Weerwolf’ sessions in Lunteren, our walks to Jumbo, and all our other meetings.
Furthermore, I wish to mention Nicky van Foreest with whom I had lively discussions in ‘De Bres’ that usually started with fascinating mathematical related topics but often quickly drifted away to broader discussions reflecting on the pleasures of life. To Linux enthusiast Nicky, thanks for all the good laughs, introducing the game Go to me, and the infinitely large stack of must-read books. I also want to thank Kees Jan Roodbergen for inspiring me during his master’s course and the always very engaging talks we had on both research and non-research related topics, and Leandro Coelho for the effective collaborations and the good laughs while enjoying a burger at Pappa Joe.
My outside academia friends Kevin Mann, Antwan van der Burg (who revealed a major flaw in one of my works while having a beer at Mr. Mofongo), Roos Willemsen, Fester Kroep, Vivi¨enne Haring, Jorrit Peters, Annelien Beumers, and Karen Oude Luttikhuis helped me reminding that there is also a large non-academic practical world out there.
A special thanks goes to my friend, co-author, and intellectual sparring partner Albert Schrotenboer with whom I shared an office from day zero of my PhD journey. Our many engaging, fruitful, and sometimes endless discussions, both at the university and in town while savoring a beer, made my time in Groningen very enjoyable and these moments certainly contributed to the quality and diversity of my PhD thesis. I am very grateful for our friendship and hope that many more good stories still have to come!
Finally, I want to thank all my other colleagues, friends, and family, who have all had to endure my never-ending talks about my thesis, but rest assured, it is finished! Michiel A. J. uit het Broek Sydney, November 2019
