Analytic Hierarchy Process - AHP • AHP is comprehensive, logical and structured framework • Support do decision making • Allows to improve understanding of complex decisions by decomposing the problem
AHP Procedure • IDENTIFICATION of decision problem • Form a HIERARCHY • GOAL ON THE TOP (Fundamental Objective) • DECOMPOSE into sub-goals • FURTHER DECOMPOSITION as necessary • IDENTIFY CRITERIA (attributes) to measure achievement of goals • EVALUATION • CALCULATING overall PRIORITY
AHP Procedure – Judgments and Comparisons • Numerical Representation • Relationship between two elements that share a common parent in the hierarchy • Comparisons ask 2 questions: – Which is more important with respect to the criterion? – How strongly? • Matrix shows results of all such comparisons • Typically uses a 1-9 scale
1 -9 Scale Equal Importance Moderate Importance Strong Importance Very Strong Importance Extreme Importance For compromises between the above Reciprocals of above In comparing elements i and j - if i is 3 compared to j - then j is 1/3 compared to i
