This chapter focuses on the application of AHP methodology to the case of contaminated sediment management. AHP is the “systematic pairwise comparison of alternatives with respect to each criterion . . . based on a special ratio scale: for a given criterion, alternative i is preferred to alternative j with the strength of preference given by ai, j = s; 1 ≤ s ≤ 9” (Linkov, Satterstrom et al. 2007). From these comparisons, a preference vector is constructed that is ultimately used to analyze the overall hierarchy (Linkov 2007).
