FUZZY TOPSIS APPROACH METHOD TO FLOOD VULNERABILITY ASSESSMENT

摘要

The purpose of the present invention is to provide a fuzzy topsis approach method for flood vulnerability assessment. According to the present invention, the fuzzy topsis approach method for flood vulnerability assessment includes a step for changing a histogram into a log form, a step for standardizing the value of a variable and storing the value, and a step for calculating a fuzzy matrix. [Reference numerals] (S10) Determine a proxy variable and a weighted value;(S20) Check and normalize the histogram of the proxy variable;(S30) Convert the proxy variable and the weighted value by using a triangular fuzzy number;(S40) Normalize the triangular fuzzy number;(S50) Calculate vulnerability through a fuzzy TOPSIS methodology
