I would first like to thank my thesis supervisor Pedro Parraguez Ruiz, a postdoctoral researcher at the Engineering Systems Division of the Management Engineering department at the Technical University of Denmark. When I first contacted Pedro in December 2017, I had no idea of the great choice I had just made. Throughout the semester he was always available to help me structure my thoughts, to enlighten me about possible research paths, and to discuss the endless possibilities that such research can have. Moreover, his passion for this research field and his complete availability at all times, made this experience one of the most fulfilling throughout my academic journey at DTU
