Some people's biggest dream is to climb the world's highest mountain, others to travel around the world. My dream was to become a PhD. A dream that I have a hard time believing that I have completed! It has been quite the adventure; an adventure I never could have completed alone. 'It takes a village to raise a child' and I have so many people to thank for contributing to this adventure. I might as well begin by thanking you for reading this dissertation! If we rewind to 2016, I would like to thank Jostein for asking me what I wanted to do after my engineering studies and for telling Bonnie about my dream. I am eternally grateful to you Bonnie, for believing in me and for everything you have taught me. Even though we did not complete this adventure together, you and our work mean a lot to me.Mattias, Jason and Idamy super-supervisor team! I will miss our meetings and how they were always filled with equal amount of laughter and fun as well as work. Well, sometimes it may have been more fun than work ☺ Mattias, I will never be able to express how grateful I am to you and HELIX for enabling me to continue to pursue my dream. You have taught me so much and I know that I would not have been the researcher or teacher I am today if it were not for you! Jason, it has been incredibly fun to share this whole adventure with you, going from taking doctoral courses together to you being my supervisor. Thank you for the professor's card joke, attending Academic Ceremonies and the horror movie tips. Ida, since the first time I met you in Elsinore, you have been a huge inspiration to me. I am so grateful that you wanted to be one of my supervisors. When you joined, my supervising team became complete! Thank you, Erik Eriksson, for reading an early draft of this dissertation and providing me with feedback that helped me improve it! Thank you, my work-Peter, for always being curious about my work, taking the time to discuss tampering and making me feel like a ★! Henrik, I am so happy to have you as my work-BFF! Thank you for always allowing me to come rushing into your room to pour my heart out. Your friendship means a lot! Maria H-B, I am so happy that we ended up working together, even though I did not follow your advice to pursue logistics. I look forward to many more long lunches and coffee breaks! I would also like to thank my fantastic colleagues at the Department of Logistics and Quality Management. When this adventure has been stressful and frustrating, you have always been there to cheer me on or provide support. I feel so lucky to work with such awesome people! To my dear family and friends. Thank you for your patience and for always being there for me. It has been some turbulent years professionally and privately, but you have stood by my side through it all. I will never be able to repay you for all the love and support, but I will spend my life trying. A special thanks to my home-Peter for your love and reminders that there is more to life than work. Lots of love to Frans and Albus for being the best distance-mode co...
