Management Science is concerned with developing and applying models and concepts that may prove useful in helping to illuminate management issues and solve managerial problems. The models used can often be represented mathematically, but sometimes computer-based, visual or verbal representations are used as well or instead. The range of problems and issues to which management science has contributed insights and solutions is vast. It includes scheduling airlines, both planes and crew, deciding the appropriate place to site new facilities such as a warehouse or factory, managing the flow of water from reservoirs, identifying possible future development paths for parts to the telecommunications industry, establishing the information needs and appropriate systems to supply them within the heath service, and identifying and understanding the strategies adopted by companies for their information systems. This book provides deep insight into various dimensions of issues relating to the subject.
