【摘要】:文章針對(duì)風(fēng)險(xiǎn)評(píng)估中的不確定信息問(wèn)題,提出了基于熵AHP和D數(shù)理論的方法對(duì)洪澇災(zāi)害風(fēng)險(xiǎn)進(jìn)行評(píng)估。首先將洪澇災(zāi)害風(fēng)險(xiǎn)評(píng)估指標(biāo)體系中的第三級(jí)指標(biāo)用D數(shù)表示,同時(shí)引入結(jié)構(gòu)熵權(quán)法確定相應(yīng)各級(jí)指標(biāo)的權(quán)重,進(jìn)一步基于D數(shù)合成法則給出了各地洪澇災(zāi)害風(fēng)險(xiǎn)大小的排序方案,最后通過(guò)實(shí)例驗(yàn)證了該方法的可行性。
[Abstract]:Aiming at the problem of uncertain information in risk assessment, a method based on entropy AHP and D number theory is proposed to evaluate the risk of flood and waterlogging disaster. First, the third level index in the index system of flood and waterlogging risk assessment is expressed as D number. At the same time, the structure entropy weight method is introduced to determine the weight of the corresponding indexes at all levels, and the ranking scheme of flood hazard risk is given based on the D-number synthesis rule. Finally, the feasibility of the method is verified by an example.
