Abstract

The expansion of double-income households is increasing the social interest in child care. In particular, children's entrance into elementary school is considered to be the main cause of women's career break as well as childbirth. This study proposes an optimal location selection method for caring facilities for elementary school students. As a candidate for care facilities, we selected existing child care facilities. We proposed a dual structure evaluation method that considers locational characteristics as well as mathematical optimization when selecting the optimal location. The experiment was conducted in Songpa-gu, Seoul. A total of 36 optimal locations were selected from a total of 258 candidate facilities. First, the evaluation criteria were established using public data, and the primary candidate facilities were selected by ranking the location scores. At this time mesh resampling method was used to integrate various public data into one. Next, the final care facilities were selected using the p-median method. The results chosen are not only the optimal location considering total distance but also satisfy various location criteria considering the characteristics of the care facility. We expect that the proposed method will contribute to public data convergence or utilization and it will be helpful for policy decision when selecting the optimal location for public facilities.

맞벌이 가구의 증가로 육아에 대한 사회적 관심이 커지고 있다. 특히 자녀의 초등학교 입학은 상대적으로 이른 하교시간 때문에 돌봄의 공백이 생겨 출산과 더불어 여성의 경력단절에 주된 원인으로 꼽힌다. 본 연구는 이러한 정책적 기조에 부합하여 초등학생 대상 돌봄시설의 최적 입지선정 방안을 제안하였다. 돌봄시설의 후보로 기존 아이돌봄시설을 대상으로 하였으며, 최적입지 선정 시 수리적 최적화뿐만 아니라 입지적 특성을 고려하는 이중구조의 평가방법을 사용하였다. 실험은 서울시 송파구를 대상으로 진행하였으며, 총 258개의 후보시설 중 36개의 최적입지를 선정하였다. 먼저 공공데이터를 활용하여 돌봄시설의 특성에 맞는 평가기준을 세운 후 입지점수를 매겨 이에 해당하는 1차 후보시설을 선별하였으며, 이때 다양한 공공데이터를 하나로 통합하기 위하여 격자리샘플링 방법을 사용하였다. 다음으로 선별된 시설을 대상으로 공간 최적화 모델인 p-median 방법을 활용하여 최종 돌봄시설을 선정하였다. 이렇게 선정된 결과는 총 거리를 고려한 위치적 최적해 일뿐 아니라 돌봄시설의 특성을 고려한 다양한 입지적 기준을 만족하는 값이다. 본 연구에서 제안한 방법을 통해 공공데이터 융합 및 활용도를 높일 수 있고, 공공시설 최적입지 선정 시 정책 의사결정에 도움을 줄 것으로 기대한다.
