QUAY CRANE SCHEDULING VIA CONSTRAINT PROGRAMMING
This study examines the quay crane scheduling problem (QCSP) at the seaside of container terminals. A constraint programming (CP) model is constructed by taking numerous properties of the problem such as safety margins, travel times and precedence relations into account. The performance of the proposed CP model is compared with that of algorithms presented in QCSP literature. The result from the computational experiments indicates that the proposed CP model is able to produce good results while reducing the computational time.Lastly, to demonstrate the robustness and the flexibility of the proposed model, extensions of the problem with ready times and time windows are discussed.

Before joining Koc University, she was a faculty member in the School of Business at The Hong Kong Polytechnic University, Hong Kong, from 1993 to 2004. She received her Ph.D. degree in Industrial Engineering from Bilkent University, Turkey, in 1993 and holds an M.S. degree (Bilkent University) and a B.S. degree (Middle East Technical University) both in Industrial Engineering. Prof. Oguz conducts research in the areas of bioinformatics, logistics, and scheduling in manufacturing and computer systems. Her expertise includes algorithm design and system modeling as well as providing optimizing and/or approximate solutions to the complex systems by means of computational methods. Prof. Oguz has participated in several research projects, which were funded by TUBITAK and jointly by the Hong Kong and the European governments, related to above fields. She has published over 40 papers in refereed journals such as Operations Research, Computers and Operations Research and European Journal of Operational Research.
Prof. Oguz took part in founding the “EURO Working Group on the Operational Research in Computational Biology, Bioinformatics and Medicine” (EURO-CBBM) and acts as the secretary and the treasurer of the group since 2006.
