Department of Systems Engineering & Engineering Management

Xiaoqiang Cai is Professor and Head of Graduate Division of the Department of Systems Engineering and Engineering Management (SEEM) at The Chinese University of Hong Kong (CUHK). He is also the Director of the Centre for Logistics and Supply Chain Optimization at the Faculty of Engineering, and the Dean of General Education of the Lee Woo Sing College of CUHK.

He received his B.Eng. degree from the Harbin Shipbuilding Engineering Institute in 1982 and his M.Eng. and D.Eng. degrees from Tsinghua University in 1985 and 1988 respectively. During 1989-91, he conducted postdoctoral research at The University of Cambridge and The Queen's University of Belfast. He was Lecturer at The University of Western Australia in 1991-1992, before joining CUHK in 1993. He served as the Head of Department of SEEM during 1996-2003, and has been Professor since October 2000.

Prof. Cai has his current research focused on scheduling models and algorithms, logistics and supply chain management, network optimization, and portfolio optimization. He has published extensively in leading journals in these areas, including Operations Research, Management Science, Production and Operations Management, Naval Research Logistics, IIE Transactions, and IEEE Transactions, with 96 journal articles and 13 books or book chapters. He has served on the editorial boards of several international journals, including IIE Transactions on Scheduling and Logistics, and the Journal of Scheduling.
