연관규칙 분석을 통한 공기지연 유발요인의 주요 특징 분석 연구 : -공기지연 분쟁 판례를 중심으로- = Key Characteristics of Factors Causing Construction Delays based on Association Rules Analysis : -Focusing on Disputes Precedent Cases of Construction Delays-

국문 초록 (Abstract)

건설공사에는 다양한 리스크가 내재되어 있으며, 분쟁을 발생시킬 수 있는 소지를 지니고 있다. 특히 공기지연은 많은 분쟁사례들과 관련이 있으며, 발생하는 원인과 형태가 복잡하고 다양하다. 공기지연이 발생하면 발주자와 시공사 모두 부정적인 영향을 받기 때문에 공기지연을 선제적으로 대응하는 것은 필수적이다.
공기지연 원인과 관련하여 다양한 연구들이 수행되어 왔지만, 유발요인간의 관계 분석은 미흡하고, 여러 분석기법에 따른 결과의 비교를 바탕으로 문제해결 방안을 제시하는 연구는 미흡한 것으로 나타났다.
본 연구의 목적은 요인간의 연관성을 도출하는데 활발히 활용되고 있는 연관규칙 분석을 활용하여 공기지연 유발요인들의 연관규칙을 도출하고, 빈도분석과 비교하여 주요 특징 및 시사점을 제시하는데 있다. 본 연구에서는 국내 최다 판례 데이터를 제공하는 빅케이스에 제시된 공기지연 분쟁사례 데이터를 바탕으로, SPSS 프로그램을 활용하여 연관규칙 분석을 통해 연관성 높은 규칙들을 도출하였고, 특징과 시사점을 제시하였다.
분석결과 첫째, 전체 연관규칙 257개 중 연관성 높은 규칙 13개가 도출되었다. 둘째, 공기지연 유발요인의 연관성을 파악할 수 있기에, 중점적으로 관리할 공기지연 유발요인을 도출할 수 있었다. 셋째, 빈도분석 결과와의 비교를 통해 빈도수가 많다고 많은 연관규칙이 도출되는 것은 아닌 것으로 분석되었다. 넷째, 어떤 선행 유발요인이 추후 유발요인과 관계가 있는지를 알 수 있기에 요인간의 우선순위를 세우고 대비할 수 있음을 확인하였다. 마지막으로 분석을 통해 나타난 특징에 따라 발주자와 시공사 관점의 시사점을 제시할 수 있었다. 이는 본 연구가 공기지연 발생가능성을 줄이고, 건설과 관련된 다양한 분쟁의 연관관계 분석을 위해 활용될 수 있는 확장성을 지니고 있다는 것을 의미한다.
