AHP-General Idea AHP algorithm is basically composed of four steps: 1.Construct the hierarchy structure(Goal,Criteria, Alternatives) 2. Construct the pairwise comparison matrix 3.Compute the weight and check the consistency for one layer 4.Determine the relative rankings(priorities)of alternatives 5.Make the overall decision Both qualitative and quantitative information can be compared by using informed judgments to derive weights and priorities.
