The field of Decision Science studies judgments and decisions by individuals, groups and organizations. Research in this area can be classified into three categories: the normative approach studies how people should make decisions if they are making choices in their best interests; the descriptive approach delves into the psychology of individuals and groups to understand how people actually make decisions; and the prescriptive approach develops methods and techniques to improve decision making. By its nature, Decision Science research is highly interdisciplinary, maintaining ties with fields such as psychology, economics, and statistics. Decision Science focuses on a number of challenging research themes which include judgment under risk, dealing with uncertainty, choosing among risky alternatives, judgmental forecasting, forecast support systems, risk perception and risk communication.
Operations Management is concerned with gaining knowledge, skills, and expertise needed to manage and advance the efficiency and productivity of business operations. Operations Management studies emphasize the development of models, methods, applications, and algorithms as they apply to problems in production and services. Management of resources, the distribution of goods and services to customers, and the analysis of queuing and inventory systems are also within the scope of Operations Management. The research interests of the Operations Management faculty follow up-to-date business practices and needs, with emphasis on revenue management, perishable and recyclable inventory control, health care ma nagement, supply chain contracts, production and customer order scheduling, and coordination issues in inventory management, supply chain scheduling, and new product development.
