Introduction

Dr. Susan H. Xu is Professor of Management Science and Supply Chain Management at Pennsylvania State University. She currently serves as the Dirctor of the PhD Program in Smeal College of Business.  She served as the Chair of the Intercollege Dual-Title Degree Graduate Program in Operations Research at Penn State from 1998-2007.  She held visiting positions in several universities including George Mason University, University of California at BerkeleyChinese University of Hong Kong,  The Hong Kong University of Science & Technology, Georgetown University, University of Maryland, National University of Singapore, and Singapore Institute of Manufacturing Technology, among others.


Current Research

Dr. Xu’s primary research interests are centered on design, performance evaluation, simulation and optimization of stochastic operating systems and their applications in supply chain management and service systems, telecommunication, information technology, and reliability.  In particular, she is interested in production and inventory systems, risk management of supply chain, revenue management, queueing control, stochastic ordering of multivariate stochastic processes, maintenance policies and risk analysis in reliability systems.  Her research is currently supported by NSF grants CMMI-0825960 and CMMI-1000183 and the Competitive Research Program in Smeal College of Business.
