Introduction

Dr. Susan H. Xu is Professor of Management Science and Supply Chain Management at Pennsylvania State University. She served as the Chair of the Intercollege Dual-Title Degree Graduate Program in Operations Research at Penn State University from 1998-2007.  She held visiting positions in several universities including George Mason University, University of California at Berkeley,  Chinese 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, stochastic scheduling, technology management, queueing control, Markov decision processes, maintenance policies and risk analysis in reliability systems, and stochastic ordering of multivariate stochastic processes.
