Prof.George Zhang
Western Washington University, USA
Professor
Zhe George Zhang is a professor of Management Science in the
Department of Decision Sciences at Western Washington University
and a professor of Operations Management in Beedie School of
Business at Simon Fraser University. He is also visiting
professor of Sauder School of Business at the University of
British Columbia. Dr. Zhang received his BS in Computer Science
and MA in Economics from Nankai University, China; his MBA from
the Schulich School of Business at York University; and his PhD
in Operations research from the University of Waterloo.
Professor Zhang has published many papers in prestigious
journals such as Management Science, Operations Research,
Manufacturing & Service Operations Management, Production and
Operations Management, IIE Transactions, IEEE Transactions,
Queueing Systems, Journal of Applied Probability. Co-authored
with Professor Tian in 2006, he published the research monograph
"Vacation Queueing Models - Theory and Applications," the first
book on this particular topic (now highly cited). Professor
Zhang's research interests include queueing theory and
applications and stochastic models for manufacturing and service
systems. The main theme of his research is to bridge the gap
between theory and application, obtaining unobservable and
sometimes counter-intuitive but significant/practical management
insights via modeling and quantitative analysis. Currently, he
is particularly interested in the quantitative and economic
analysis of the congestion problems in urban/mass transportation
networks, health/medical care systems, and public service
systems with both customer service quality and security
concerns. As an expert in data analysis and quantitative
modeling, he has consulted in industry and has given research
seminars and short lectures at leading universities around the
world. He was invited to present plenary or keynote talks in
several international conferences.Professor Zhang is the one of
Editor-in-Chiefs for new journal Queueing Models and Service
Management, aan associate editor of INFOR (Information Systems
and Operations Research), and is on the editorial board of
several international journals in Operations Research and
Management Science.

Title: The generalized age maintenance policies with random working times
Abstract: The purpose of this paper is to
investigate the generalized age maintenance policies for a
system with random working times. When the system fails, it is
subject to one of two types of failures with age-dependent
probability: type I failure can be removed by minimal repair and
type II failure must be rectified by replacement. First, the
system is preventively replaced before type II failure at time T
or at the completion of Nth working projects, whichever occurs
first. Two modified models, where the system is preventively
replaced before type II failure at time T or at the completion
of Nth working projects, whichever occurs last, and it is
preventively replaced at the first completion of the working
project over time T or at the completion of Nth working
projects, whichever occurs first, are considered. By introducing
costs due to repairs, maintenance and replacement, the expected
cost per unit time is derived as a criterion of optimality and
the optimal policy that minimizes that cost is discussed
analytically.

Chan
The Hong Kong Polytechnic
University, Hong Kong
Professor Felix T. S. Chan received his BSc Degree in Mechanical Engineering from Brighton Polytechnic (now University), UK, and obtained his MSc and PhD in Manufacturing Engineering from the Imperial College of Science and Technology, University of London, UK. Professor Chan is now working at the Department of Industrial and Systems Engineering, The Hong Kong Polytechnic University, and also serving as Associate Dean (Research) at the Faculty of Engineering. His current research interests are Logistics and Supply Chain Management, Operations Management, Distribution Coordination, Systems Modelling and Simulation, AI Optimisation. To date, he has published 16 book chapters, over 300 refereed international journal papers and 250 peer reviewed international conference papers, h index= 30 under the Web of Science. He is a chartered member of the Chartered Institute of Logistics and Transport in Hong Kong. According to a study lately published in the International Journal of Production Research (http://dx.doi.org/10.1080/00207543.2015.1037935), the study measured the research contributions over a 26-year time frame (1985-2010) of academic institutions and individual authors to the field of Operations Management (OM) based on published articles in 11 top-rated and well-known academic OM journals. Professor Chan was among the top 50 prolific authors list who have made the greatest overall contribution to the field as measured by the number of distributed and shared articles published in the 11 designated journals. Also, Professor Chan was Ranked No. 3 in The top 100 authors as the most productive researchers in the field of Operations Management over the past 10 years (2001-2010).
