As the global economy continues to be turbulent, production and operations managers in all organizations are facing more challenges -- shorter product life, more intensive competition, rapider response, increased product variety, and faster information flows. As a result, the interaction of operations with other functional areas such as R&D, engineering, marketing, finance, accounting, personnel, strategy, and information systems have become increasingly important. The production and operation management has also been applied to many other areas, such as healthcare systems, humanitarian supply chains, and natural resources management. The theme of the meeting, Variety, Integration and POM, recognizes such a trend. In addition, this is the first attempt that the conference is co-organized by two universities (one from Hong Kong and one from mainland). The Sixth POMS-HK International Conference will provide a forum for practitioners and academics to share their research, experience, and insights on thematic areas as well as traditional POM problems.
