다목적 화음탐색법(MOHS)을 이용한 LID 시설 최적설계 = Optimal Design of LID Facilities Using Multi Objective Harmony Search

다국어 초록 (Multilingual Abstract)

Due to urbanization, rainfall runoff and nonpoint pollution sources are increased, resulting in problems such as flooding, urban heat island and river water quality. This has increased the importance of low impact development (LID) to effectively control runoff and pollutant loads in impervious areas. In order to install LID facilities, cost and environment effect should be evaluated considering scale and type of facility. The purpose of this study is to conduct a multi objective optimization simulation with harmony search algorithm connected SWMM for water environment restoration effect and cost for LID facilities such as permeable pavement, infiltration trench, and tree box filter and to make the relations between objective functions. In addition, an ideal point and a compromise solution are selected from Pareto Optimal Front between environmental effect as runoff and pollutant load within a limited budget.

국문 초록 (Abstract)

도시화로 강우유출량과 비점오염원의 배출량이 증가되어 침수가중, 도심 열섬 가중, 하천수질저하 등의 문제를 발생시킨다. 이로 인하여 불투수면에서의 유출과 오염부하를 효과적으로 제어하기 위한 저영향개발(LID)의 중요성이 커지고 있다. LID 시설을 설치하려면 규모 및 시설종류 등을 고려하여 설치비용과 저감효과를 평가하여야 한다. 본 연구는 다목적 화음탐색법을 SWMM과 연계한 모형을 구축하여 투수성포장, 침투트렌치, 나무여과상자 등의 LID 시설에 의한 물 환경 복원효과와 설치비용에 대한 최적화모의를 하고 상충관계에 있는 두 목적함수간의 추정관계를 제시하였다. 또한 제한된 예산범위에서 LID 시설의 유출저감효과와 오염물질배출의 파레토 최적 프론티어로부터 추정된 두 목적함수와 설치비용과의 관계로 유추된 이상점으로부터 절충해를 선정하여 최적의 값을 도출하였다.
