This course introduces students to some of the main concepts and theories that have emerged in the field of "decision support systems". Decision Support Systems (DSS) represent a powerful class of IT that is specifically designed to assist the decision maker in the current data-rich but information-poor environment. DSS applications have the effect of enhancing the efficacy of decisions, particularly in highly uncertain, constrained, complex and dynamic environments, as well as increasing decision-making speed, quality, traceability and consensus. In the class work, students will be asked to model and analyze business case studies using specialized computer software tools. The course work will help students to gain experience and better understanding of deploying such systems in real-time decision making in business settings, and their use off-line in strategy and policy development.
