Multilevel Fuzzy Approach to the Risk and Disaster Management

Abstract

In this paper a short general review of the main characteristics of risk management applications is given, where a hierarchical, multilevel risk management method can be applied in a fuzzy decision making environment. The given case study is a travel risk-level calculation based on the presented model. In the last section an extended model and a preliminary mathematical description is presented, where the pairwise comparison matrix of the grouped risk factors expands the previous principles.
