The Decision Analysis Society promotes the development and use of logical methods for improving decision-making in public and private enterprise. Such methods include models for decision-making under conditions of uncertainty or multiple objectives; techniques of risk analysis and risk assessment; experimental and descriptive studies of decision-making behavior; economic analysis of competitive and strategic decisions; techniques for facilitating decision-making by groups; and computer modeling software and expert systems for decision support. Our members include practitioners, educators, and researchers with backgrounds in engineering, business, economics, statistics, psychology, and other social and applied sciences.

The Decision Analysis Society is a subdivision of INFORMS, the Institute for Operations Research and the Management Sciences. INFORMS is the world's largest organization of operations researchers and management scientists, with over 12,000 members. The Decision Analysis Society is among the largest of INFORMS' subdivisions, with more than 1000 members.

The Decision Analysis Society was founded in 1980 as the ORSA Special Interest Group on Decision Analysis, becoming the INFORMS Section on Decision Analysis upon the merger of ORSA with TIMS. In February 1996, the Section on Decision Analysis became the Decision Analysis Society.
