The Analytic Hierarchy Process (AHP) is a technique for dealing with complex decisions where a number of competing factors demand consideration. It is especially suited to problems with high stakes, involving human perceptions and judgments, whose resolutions have long-term repercussions.[1] AHP provides a comprehensive and rational framework for structuring a problem, for representing its elements and quantifying them, for relating those elements to overall goals, and for evaluating alternative solutions.

While it can be used by individuals working on straightforward problems, AHP is most commonly applied where teams of people are working on highly complex situations, particularly where some of the elements are difficult to quantify. Computer software is available to assist in the application of the process.

Developed in the 1970s by mathematician Thomas L. Saaty, AHP has been applied worldwide, in a wide variety of decision situations, in fields such as government, business, industry, healthcare, quality, and education.

Uses of AHP

The applications of AHP to complex decision situations number in the thousands,[2] typically where problems are important and complex. Many such uses are never reported to the outside world, because they take place at high levels of large organizations, where security and privacy considerations prohibit their disclosure. But some uses of AHP are discussed in the literature. Recently these have included:

  • Deciding how best to reduce the impact of global climate change (Fondazione Eni Enrico Mattei)[3]
  • Quantifying the overall quality of software systems (Microsoft Corporation)[4]
  • Selecting university faculty (Bloomsburg University of Pennsylvania) [5]
  • Deciding where to locate offshore manufacturing plants (University of Cambridge)[6]
  • Assessing risk in operating cross-country petroleum pipelines (American Society of Civil Engineers)[7]
  • Deciding how best to manage U.S. watersheds (U.S. Department of Agriculture)[2]

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, then to justify its budget to lawmakers.[8]

The process is widely used in countries around the world. At a recent international conference on AHP, over 90 papers were presented from 19 countries, including the U.S., Germany, Japan, Chile, Malaysia, and Nepal. Topics covered ranged from Establishing Payment Standards for Surgical Specialists, to Strategic Technology Roadmapping, to Infrastructure Reconstruction in Devastated Countries.[9] AHP was introduced in China in 1982, and its application has expanded greatly since then—its methods are highly compatible with the traditional Chinese decision making framework, and it has been used for many decisions in the fields of economics, energy, management, environment, traffic, agriculture, industry, and the military.[10]

How AHP works

Under Construction

  1. Express the problem as a hierarchy.
  2. Establish priorities for the elements of the hierarchy.
  3. Investigate the logical consistency of the priorities established in step 2.

Teaching AHP

Though using AHP requires no specialized academic training, the subject is widely taught at the university level—one AHP software provider lists over a hundred colleges and universities among its clients.[11] AHP is considered an important subject in many institutions of higher learning, including schools of engineering[12] and graduate schools of business.[13] AHP is also an important subject in the quality field, and is taught in many specialized courses including Six Sigma and QFD.[14][15][16]

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.[10]
