Dr. Cheng Hsu is Professor of Industrial and Systems Engineering and Professor of Information Technology, Rensselaer Polytechnic Institute, Troy, NY12180-3590. He earned a Ph.D. degree from the Ohio State University in Management Sciences (with a minor in Computer Science), MS in Industrial and Systems Engineering from Ohio State University, and BS in Industrial Engineering from Tunghai University, Taiwan. He served on Rensselaer's Faculty Council, Faculty Senate, and various other academic committees at the school and institute levels (e.g., the Institute-wide BS-IT and MS-IT curricula committees). He has been a keynote speaker to a number of international meetings in Taiwan, Hong Kong, Thailand, Italy, and Canada, as well as in the US. Dr. Hsu is currently engaging in research on service science, with a focus on service design and system design. He developed a thoery of Digital Connections Scaling to help explain the dynamics of new service in the connected world. The theory recognizes population-wide connected value cocreation among persons and organizations as a transforming mode of production for Knowledge Economy, and thereby analyzes new busness designs and service system design laws. A new model accompanies the theory: Hyper-Networks, which engages the emerging network science to provide insights into the analytic nature of connected value cocreation. New system design methods aim at helping scale IS up to the populations of customers, providers, and resources; down to individual users; and transformational to cross-sectional collaboration. The theory is also suported by such results as instrumentation of the environments (using, e.g., RFID systems, wireless sensor networks), Cyber-Infrastructure-Assisted Enterprises, and the market approach to open and scalable information exchange. He is a believer of person-centered models on the Internet. In addition to the above original work on serfvice science, Dr. Hsu is also devoted to studying sustainability design for products and production systems, and alternative energy system design for micro grids at the community level. The originator of the Metadatabase and Two-Stage Entity-Relationship Models, Dr. Hsu's work have contributed to much of the research on these topics as reported in this Web site, Enterprise Integration and Modeling. He has been a principal investigator of Rensselaer's Computer-Integrated Manufacturing and Adaptive Integrated Manufacturing programs, and a number of other government- and industry-sponsored projects. The sponsors include companies such as Alcoa, Digital, GE, GM, IBM, and Samsung Electronics, and government sources such as the U.S. National Science Foundation, Army Research, New York State, and NATO. Dr. Hsu teaches Multi-disciplinary Capstone Engineering Design, Discrete Systems Simulation, Databases, e-Business engineering, and Information Systems. His publications include a number of books and edited volumes, and over a hundred scholarly papers in a number of archivaljournals and proceedings. He is a member of AIS, IEEE and ASEE. He has served and continue to serve on the editorial board for several journals and organizations, including, e.g., IEEE Transactions on Systems, Man, and Cybernetics.
