Abstract

Accident rate in the construction industry of South Korea is increasing every year, and it represents the highest percentage among industries. This shows that activities performed to prevent safety accidents in the country are not efficient when it comes to reduce the accident rate. In order to resolve this issue, a model for the prediction of human accidents should be established. In addition, it is required a quantification study based on pattern of human accidents. Therefore, the objective of this study is to quantify uncertainty of human accidents risk and predict how to change in various circumstances by using Monte Carlo Simulation. To achieve the objective, first, pattern of human accidents was defined. Second, insurance claim payout and information of human accidents during 14 years in construction site were collected. Third, descriptive analysis is conducted to determine the characteristics of the accident pattern. Fourth, to quantitatively analyze the pattern of the human accidents, the population of each accident occurrence and payout were estimated. Finally, estimated populations was analyzed according to characteristics of distribution by using Monte carlo simulation. In the future, this study can be used as a reference for developing the safety management checklist in construction site and development of prediction models of human accident.

한국 건설업의 재해율은 매년 증가하고 있는 추세이며 다른 산업에 비해 월등히 높다. 이는 국가차원에서 재해예방을 위해 수행하는 안전활동들이 건설산업의 재해율 감소에는 효과를 보이지 못한다는 것을 의미한다. 이러한 문제점을 해결하기 위해서는, 인명사고 예측모델에 대한 프레임이 구축되어야 하며, 인명사고 발생형태에 대한 정량화 연구가 필요하다. 이에, 본 연구는 인명사고 발생형태의 불확실성을 정량화하고 몬테카를로 시뮬레이션을 통해 다양한 환경에서 어떻게 변화하는지 예측하고자 한다. 이를 위하여 첫째, 선행연구 고찰을 통해 인명사고 발생형태를 정의한다. 둘째, 14년 간 국내 건설현장에서 발생한 인명사고 및 보상지급액 데이터를 수집한다. 셋째, 발생형태별 특성을 파악하기 위해 수집된 데이터를 토대로 기술통계분석을 실시한다. 넷째, 인명사고 발생형태를 정량적으로 분석하기 위하여 발생형태별 사고 발생 확률과 보상지급액의 모수를 추정한다. 마지막으로 추정된 모집단을 토대로 몬테카를로 시뮬레이션을 실시하여 인명사고 발생형태별 분포 특징을 분석한다. 본 연구의 결과는 향후 건설현장 안전관리 체크리스트 개발 및 인명사고 예측 모델 개발의 참고 자료로 활용될 것으로 기대된다.
