Abstract:
Analytic Hierarchy Process (AHP) is major method for decision making, and iInner dependence AHP is used for cases in which criteria or/and alternatives are not independent enough. Using the original AHP or inner dependence AHP may cause results that cannot have enough reliability because of the inconsistency of the comparison matrix. In such cases, fuzzy representation for weighting criteria or/and alternatives using results from sensitivity analysis is useful. In the previous papers, we defined local weights of criteria and alternatives and overall weights for double inner dependence AHP (among criteria and among alternatives, respectively) via fuzzy sets. In this paper, we extend these weighs to those of triple inner dependence structure AHP (among 2 levels of criteria and among alternatives, respectively)
