Online scheduling and project scheduling

Composition of the Graduation Committee:This thesis is the result of four years working together with many interesting people.Therefore, it seems unfair that only my name is on the cover of this book.I would like to pause and say a few words of thanks.First and foremost, I have to thank Johann Hurink.Back when I was writing my Master's thesis he was the one who encouraged me to pursue a Ph.D. degree.He gave me the opportunity and freedom to work on the scheduling problems described in this thesis.The advice he gave me as a supervisor and sometimes as a mentor was of great value to me.I enjoyed the many discussions we had, both on and off subject.By enjoying each others suggestions and enthusiasm, and by debating as being peers, he gave me much more than I could possibly ask for.Secondly, I am thankfull to the people that I had the privilege and pleasure to worked with, in particular to Marco Schutten and Walter Kern.Our stimulating discussions and their insights are of great value to me and my work.The research done together with Tom Guldemond and Leendert Kok has not only resulted in their graduation
