In the early 1970s, the Analytical Hierarchy Process (AHP), which is not generally known as a forecasting method, was created by Thomas L. Saaty to solve multi-criteria decision making problems. The AHP approach was designed to help decision makers incorporate qualitative (intangible) and quantitative (tangible) aspects of a complex problem. It systematically solves complex problems by decomposing the structure of a problem into hierarchies and the users then make pairwise comparison judgments as to importance or preference to develop priorities in each hierarchy
