Abstract
This chapter presents a review on risk assessment methodologies that incorporate fuzzy analytic hierarchy process (FAHP). We classify FAHP applications from the Institute for Scientific Information (ISI) Web of Knowledge database into two main categories: fuzzy singular analytic hierarchy process and fuzzy hybrid analytic hierarchy process. We considered five criteria in our taxonomy: (1) Did the study perform group decision-making? (2) Did the study differentiate each decision maker's competence according to their background and experience? (3) Did the study model the decision maker's risk attitude? (4) Did the study perform sensitivity analysis? (5) Did the study validate the proposed model? The studies are then grouped into four explanatory fields: (1) year of publication, (2) type of FAHP application, (3) main objective of the FAHP application, and (4) some observations based on the outcome of the abovementioned taxonomy analyses. In this stage, the information is summarized and depicted in appropriate tabular formats and graphical charts for a quick interpretation on review trends. Some managerial insights are then provided. Pragmatically, this work serves as a guide to researchers who are seeking for research gaps in the area of risk assessment and FAHP models.
