Abstract
In this study, the analytic hierarchy process (AHP) and fuzzy AHP weighting methods are used to assess regional investment priorities. According to an annual disaster report, we confirmed that disasters such as floods were generally more severe and more detrimental to males than females. Many studies on flood vulnerability have been conducted to reduce damages caused by floods and natural disasters at home and abroad. However, research on vulnerability analyses that consider gender has been insufficient. This work selected 25 wards in Seoul, Korea, as the study area, for which the vulnerability index was calculated using the AHP and fuzzy AHP weighting methods. The flood-vulnerability index was calculated under two cases, i.e., with and without considering gender factors such as the female population ratio. As a result, we confirmed that the vulnerability ranking varies according to the index. Because the ranks of the vulnerability indexes are different, we need to consider methods that include gender factors in designing regional risk priorities in the future when implementing flood countermeasures at a regional level.
Key Words: PSR, AHP, Fuzzy AHP, Flood Vulnerability, Gender Factors
요지
본 연구에서는 서울시 지역의 홍수취약성을 평가하는 방법으로 평가에 사용되는 인자들을 PSR 로 나누어 AHP가중치방법과 Fuzzy AHP 가중치방법을 이용하였으며, 지역의 투자 우선순위를 파악하고자 한다. 더불어 재난 발생 시 남성보다 여성의 피해가 더 크다는 문제점이 보고되고 있음에도 불구하고 젠더특성을 고려한 취약성 분석은 부족한 실정이다. 이의 피해를 저감시키기 위해 연구대상 지역으로 서울시 25개구를 선정하였으며, AHP가중치방법과 Fuzzy AHP가중치방법을 이용하여 취약성지수를 계산하였다. 취약성지수는 여성인구비율과 같이 젠더 특성의 여성관련 인자들을 고려한 경우와 고려하지 않은 경우로 나누어 계산되었다. 그 결과 지수별로 취약성 순위가 달라짐을 확인하였다. 지수별 취약성지수의 순위들이 각각 다르기 때문에 향후 젠더요소를 포함한 지역들의 홍수대책 사업 등을 실시할 경우 지역의 위험우선순위를 두는 방안들이 검토되어야 될 것으로 판단된다.
핵심용어: PSR, AHP, Fuzzy AHP, 홍수취약성, 젠더 특성
