Research on the Assessment of Disaster-carrying Bodies' Comprehensive Vulnerability on Variable Fuzzy Clustering

摘要

The disaster-carrying bodies' comprehensive vulnerability is a key to the risk research of urban disaster. Vulnerability is a comprehensive attribute of the hazard-carrying bodies and is affected deeply by society, economic and environment. The index system of the vulnerability assessment is worked out with the method of variable fuzzy clustering. The comprehensive vulnerability index model is structured, and the comprehensive vulnerability is calculated in the following example. Comparative to the existing research, variable fuzzy clustering and comprehensive vulnerability index model are more objective in data processing and the influence of the clustering categories is reduced.
