Sébastien Thomassey (PhD) is currently associate professor at the "Ecole Supérieure des Arts et Industries Textiles" (ENSAIT) and the GEMTEX laboratory. He gained an MSc(Eng.) in textile and clothing production from the ENSAIT in 1999, an MSc in advanced data analysis from the Lille I University in 1999 and a PhD in automation and information technology from the Lille I University in 2002. He was an engineer in R&D at the French technical center for the textile/clothing, IFTH, from 1999 to 2002 and a researcher at the Mathematic and Operational Research Laboratory of the Polytechnic Institute of Mons in Belgium in 2003. His research is mainly focused on the implementation of soft computing and data mining techniques for modeling, simulation, supply and production chain optimization, forecasting sales of clothing products, clustering, classification and decision support systems for textile/apparel industry. His work has been published in refereed journals, such as Applied SoftComputing, Decision Support Systems, European Journal of Operational Research, and the International Journal of Production Economics,. He is actively involved in research projects in production and supply chain management, sales forecasting and clustering/classification of fashion products.

He has also participated in various European and national research projects related to sustainable textile design and management, simulation and optimization of manufacturing units, clustering and classification of 3D morphologies for intelligent sizing systems, and sales-forecast-based simulation in pricing strategy.

X.Y. Zeng received the B.Eng. degree from the Department of Science and Technology, Tsinghua University, Beijing, China, in 1986, and the Ph.D. degree from the Centre d'Automatique, Université des Sciences et Technologies de Lille, Villeneuve d'Ascq, France, in 1992. He is currently a Full Professor with the French Engineer School, Ecole Nationale Supérieure des Arts et Industries Textiles (ENSAIT), Roubaix, France. Since 2000, he has led the Human-Centered Design research team in ENSAIT. He has published two scientific books, more than 260 papers at reviewed international journals, and international conference proceedings. His research interests include: 1) intelligent decision support systems for fashion and material design, 2) modeling of human perception and cognition on industrial products, 3) intelligent wearable systems.

Dr. Zeng is currently an Associate Editor of International Journal of Computational Intelligence System and Journal of Fiber Bioengineering and Informatics, a Guest Editor of Special Issues for six international journals, and a senior member of IEEE. He has organized 12 international conferences and workshops since 1996. Since 2000, he has been the leader of three European projects, four national research projects funded by the French government, three bilateral research cooperation projects, and more than 20 industrial projects.
