Dr. Hing Kai Chan joined the Norwich Business School of the University of East Anglia in September 2007 and is now a Senior Lecture in Operations and Supply Chain Management. He has been conducting research with the applications of soft computing like fuzzy logic for several years. He has extended his research to cover supply chain management in recently years for his PhD study by employing multi-agent approaches for analyzing the performance of distributed supply chains. In recent years, Dr. Chan started employing genetic algorithms for solving scheduling problems. He has studied some production and distribution models, which are structured in two-level and three-level multi-factory production environment, operating in mass production. In short, Dr. Chan has expertise on the formulation of optimization models and heuristic solution approaches, such as linear programming, integer programming in various decision support systems. To date, he has published over 60 refereed international journal papers, including leading journals like various IEEE Transactions, International Journal of Production Economics, International Journal of Production Research, Decision Support Systems, Expert System with Applications. He also published more than 30 refereed conference papers.   Dr. Xiaojun Wang joined the School of Economics, Finance and Management of the University of Bristol as a lecturer in management in September 2011. Before that, he worked at Norwich Business School of the University of East Anglia as the lecturer in supply chain management for two years. He obtained his PhD from the University of Liverpool, where he developed an approach to improve food supply chain performance through integration of traceability system with operations management decisions. In recent years,Xiaojun’s main research focuses on provision of new business models to support decision making process through the analytical modeling approach. For example, he has been conducting research on risk assessment models using fuzzy set theory and multi-criteria decision making approaches such as analytical hierarchy process and analytical network process. The research has been applied in many industry sectors and published in leading international journals such as International Journal of Production Economics, International Journal of Production Research and Production Planning and Control.
