Prior to coming to the University of Pittsburgh, Thomas L. Saaty was a professor at the Wharton School, University of Pennsylvania for 10 years and before that was for seven years in the Arms Control and Disarmament Agency at the U.S. State Department. He is a member of the National Academy of Engineering and serves on the Board of Advisors to Decision Lens, a company based on the Analytic Hierarchy Process (AHP). He is the architect of the decision theory, the Analytic Hierarchy Process (AHP) and its generalization to complex decisions with dependence and feedback, the Analytic Network Process (ANP).
In 2000 he received the Gold Medal for his work on decision making from the International Society for Multi-criteria Decision Making. In 2007 he received the Akao prize given by the Quality Function Deployment (QFD) society. In 2008 he received the Impact Prize from INFORMS (the society for Operations Research) for his seminal work on the Analytic Hierarchy Process and for his contribution to its deployment and its extraordinary impact. In 2009 he received the Chancellor's Distinguished Research Award at the University of Pittsburgh.
The International Symposium on the Analytic Hierarchy Process (ISAHP) that takes place every two years was established in 1988. Recent meetings have been in Bern, Switzerland, 2001 (Sixth ISAHP); in Bali, Indonesia, 2003 (Seventh ISAHP); in Hawaii, 2005 (Eighth ISAHP); in Viña del Mar, Chile, 2007 (Ninth ISAHP); in Pittsburgh, United States, 2009 (Tenth ISAHP). The next meeting will be held in 2011 in Naples, Italy.
He has published numerous articles and more than 12 books on the AHP/ANP and decision making and the workings of the brain. His nontechnical book on the AHP, Decision Making for Leaders, has been translated to more than 10 languages. He is also the author of numerous other books on mathematics and mathematical modeling.
His 2009 book, Principia Mathematica Decernendi: Mathematical Principles of Decision Making, draws together his thinking and work on decision making. It expands on the central idea of his theory that human judgment as solicited through simple pairwise comparisons can be used to create scales for both tangibles and intangibles. In classical theory scales are invented and used to measure, but in the end what the measurement means must be interpreted depending on which human values are to be served. Using the AHP, the judgment process is integrated from the beginning starting with the pairwise comparison judgment. The theory evolved to decision making using hierarchical structures and from that to decision making in networks with dependence and feedback and complex decision making involving Benefits, Opportunities, Costs and Risks. His work on group decision making currently is widely used to facilitate decision making in organizations and is being applied to the negotiation of conflicts.
He supervised the Super Decisions software that implements the ANP for decision making in networks and makes it available free to researchers and educators at www.superdecisions.com.
The AHP is used in both individual and group decision-making by business, industry, and governments and is particularly applicable to complex large-scale multiparty multi-criteria decision problems. He has consulted on key decisions for, among others, Merck, IBM, Ford Motor Company, the Environmental Protection Agency, the Department of Energy and the State Department. The ANP has been applied to a wide variety of decisions involving benefits, costs, opportunities, and risks and is particularly useful in predicting outcomes. It was used to successfully predict the month the economy would turn around during the 1991 and 2001 recessions. At the Pitt Graduate School of Business he teaches Decision Making in Complex Environments as well as a popular course on Creativity and Problem Solving.
He has made contributions in the fields of operations research (parametric linear programming, epidemics and the spread of biological agents, queuing theory, and more generally behavioral mathematics as it relates to operations). He also made contributions in arms control and disarmament, writing a book on mathematical models in that field, and in urban design, where he coauthored the book Compact City with George B. Dantzig. He has written books and articles in graph theory and its applications, nonlinear mathematics, analytical planning, and game theory and conflict resolution. His book, The Brain: Unraveling the Mystery of How It Works, generalizing the ANP further to neural firing and synthesis, appeared in the year 2000. Some of the research on neural synthesis was done in collaboration with Luis G. Vargas.
His current hobbies are collecting jokes and maintaining his world-wide joke list, caring for his garden (coffee-grounds are his latest find as the best fertilizer ever), and collecting new stories and ideas about the creative process.
Decision Making: Developing the mathematical theory of the Analytic Network Process (ANP) for decisions with dependence and feedback to decisions with benefits opportunities, costs and risks. The ANP is a generalization of the Analytic Hierarchy Process (AHP) which has been used to assist governments and corporations in making such decisions as: trading off weapon systems in arms control negotiations, defending against attacks by terrorists and the feasibility of acquiring manufacturing plants in overseas countries in the face of strong competition.
Conflict Resolution: Applying the Analytic Network Process to propose solutions to a variety of international conflicts discussed in the 1989 book Conflict Resolution. Chapter 11 in that book proposed a step-by-step solution to the conflict in South Africa and grew out of a study commissioned by the Government of South Africa in 1986. He has used the ANP to determine the best strategy for the 2003 US war in Iraq (withdrawal from cities and having quartered troops on site) . More recently he has worked with a number of colleagues and participants representing the two sides to determine that a two-state solution is best for theand several works after including the 2003 war in Iraq and the IsrealiIsraeli-Palestinian conflict. The process continues with support from various organizations. He has proposed and published on creatingProposed and widely circulated the creation of an International Center for Conflict Resolution (ICCR) in a neutral country. Corresponded and visited with interested world leaders. He is concerned about the spread of terrorism and the use of nuclear weapons. around the world and the increasing threat of a world war. He is also concerned about international conflicts that may arise from the world's growing concern with climate change and environmental pollution.
Process thinking as an advance in systems thinking suggests that systems are always subject to change and improvement, and this applies to our world in general and its integration through the spread of ideas and through trade and interdependence. There is no holding back of the progressive forces shaping the future of mankind. He is writing a book to show that the AHP/ANP is a natural way for people to work together by laying out their goals and purposes to plan and design systems that allow for change and for improvement. Saaty has developed and extensively applied a practical method for projecting the likely future based on the use of both tangible and intangible factors and for working backwards to identify strategies to better attain desired futures.
