Fuzzy stochastic simulation method for comprehensive risk assessment of regional natural disaster
Translated Abstract
An index system of comprehensive risk assessment for regional natural disaster risk was established in terms of the risk of natural disasters, socio-economic vulnerability and regional fortification.According to many uncertaintyfactors such as randomness, fuzziness and the shortage and imprecision of datum information of compre -hensive risk assessment for regional natural disaster risk , Monte-Carlo method was presented to simulate triangularfuzzy numbers for transforming the operations of triangular fuzzy numbers and their functions into the conventionaloperations of real numbers, and then a comprehensive risk assessment method for regional natural disaster risk usingstochastic simulation and triangular fuzzy numbers was established .The application results showed that the assess -ment expressed by confidence intervals can provide more reliability information than that of common evaluationmethods, which can reflect practical conditions of the comprehensive risk assessment method for regional naturaldisaster, and can also be applied to comprehensive risk assessment problems of different disaster risk affected bymany uncertainty factors.
