The Analytic Hierarchy Process (AHP) is a problem solving framework used in decision making. Developed in the 1970s by mathematician Thomas Saaty, it is a systematic process for representing the elements of a problem, for relating those elements to overall goals, and for choosing among alternative solutions. It has the proven ability to resolve or assist in resolving a wide range of important decision problems in business, government, transportation, and other fields.
While AHP can be used by individuals working on straightforward problems, it is best suited to situations where teams of people are working on problems that are highly complex.
Uses of AHP
The applications of AHP to complex decision situations number in the thousands.[1] It finds its widest use where problems are important and complex, and where a number of competing factors demand consideration. Because many such uses take place at high levels of governments, institutions, and corporations, security and privacy considerations prevent them from being published or publicized. Fortunately, many others are reported in the literature. Recent publications have included these, among dozens or hundreds of others:
- Deciding how best to reduce the impact of global climate change (Italy)[2]
- Quantifying the overall quality of software systems (Microsoft Corporation)[3]
- Selecting university faculty (Bloomsburg University of Pennsylvania) [4]
- Deciding where to locate offshore manufacturing plants (University of Cambridge)[5]
- Assessing risk in operating cross-country petroleum pipelines (American Society of Civil Engineers)[6]
- Deciding how best to manage U.S. watersheds (U.S. Department of Agriculture)[1]
AHP was recently applied to a project that uses video footage to assess the condition of highways in Virginia. Highway engineers first used it to determine the optimum scope of the project, and then to justify its budget to lawmakers.[7] AHP is widely used in countries around the world. Its methods are highly compatible with the traditional Chinese decision making framework, and both research and applications of AHP have made remarkable progress there since it was introduced in 1982. The process has been used for many decisions in the fields of economics, energy, management, environment, traffic, agriculture, industry, and military applications.[8]

Teaching AHP
Though using AHP requires no specialized academic training, leaders and decision makers are often taught about its uses and benefits. AHP is considered an important subject in many academic institutions, including schools of engineering[9] and graduate schools of business.[10] AHP is also an important subject in the quality field, and is taught in many specialized courses including Six Sigma and QFD.[11][12][13]
In China, nearly a hundred schools offer courses in AHP, and many doctoral students choose AHP as the subject of their research and dissertations. Over 900 papers have been published on the subject in that country, and there is at least one Chinese scholarly journal devoted exclusively to AHP.[8]
