The principal aim of this book is to examine selected contemporary research in, and applications of, operational research/management science. The focus is on research that is of industry interest and the text covers a wide range of topics from major fields of OR/MS in a systematic and coherent fashion. Each application is chosen to demonstrate the elegance of their implementations. This book could be useful to applied researchers who are interested in applications of OR/MS algorithms. Real world problems together with their solutions and implementations are the applications that have been selected for the volume. The Asia Pacific region has embraced business applications of decision support systems in recent years. Many of these applications have the state of the art OR/MS techniques in this region embedded in them. Hence, the increased use of OR/MS techniques in this region provides opportunities for identifying methodological advances that are taking place as a result of the unique nature of the applications. These also provide opportunities for exploring synergies and interfaces that exist between OR/MS, both in terms of applications and theoretical advances.
