Barış Tan


Barış Tan is currently Professor of Operations Management and Industrial Engineering and the Vice President for Academic Affairs at Koç University, Istanbul, Turkey.

He received a BS degree in Electrical Engineering from Bogazici University, and ME in Industrial and Systems Engineering, MSE in Manufacturing Systems Engineering, and PhD in Operations Research from the University of Florida. Professor Tan is teaching operations management, management science, and supply chain management courses at Koç University since 1994. He previously served as the Dean of College of Administrative Sciences and Economics and the Director of the Graduate School of Business at Koç University.

He is the recipient of Turkish Academy of Sciences Distinguished Young Scholar Award, TUBITAK fellowship, NATO Science Fellowship, and the Rockefeller Foundation Residency Award at Bellagio Center. Professor Tan held visiting positions at Harvard University Center for Textile and Apparel Research, Massachusetts Institute of Technology Operations Research Center, MIT Laboratory for Manufacturing and Productivity, University of Cambridge Judge Business School, and University College London School of Management.

Professor Tan is a member of the European Foundation for Management Development (EFMD) EQUIS Awarding Body, ISM University of Management and Economics Senate, International Advisory Boards of EM Lyon and Nottingham Business School, Education and Research Industry Strategy Council of Oracle, Research Analytics Advisory Board of Thomson Reuters, and Advisory Board of Mindspecs. He served on the Boards of EFMD, CEMS Global Alliance in Management Education, and Turkish Quality Association and Turkish Operations Research Society.


His research interests are in design, analysis and control of production systems, cooperation in supply chains, analytical and stochastic modeling techniques and business model innovation. He co-edited two books on Stochastic Models of Manufacturing Systems by Springer, special issues of IIE Transactions, Annals of Operations Research, and OR Spectrum. He is the Area Editor of Manufacturing Systems of Flexible Services and Manufacturing Journal and Associate Editor of IISE Transactions. His publications were selected as IIE Transactions Best Paper in Focused Issue on Design and Manufacturing, INFORMS Case Competition Finalist, and European Simulation Multiconference Best Paper.
