Abstract

Earthwork is a basic operation for all forms of civil works and affects construction time, cost and productivity. It is a mechanized operation that needs various construction equipment as a group and uses a lot of fuel for construction equipment. But, the problem is that earthwork operation is usually performed by equipment operator's heuristic and intuition, which can cause low productivity, high fuel consumption, and high carbon dioxide emission. As one of solutions for this problem, the fleet management system for construction equipment is suggested for effective earthwork planning, optimal equipment allocation, efficient machine operation, fast information exchange, and so forth. The purpose of this research is to suggest core methods for developing the equipment fleet management system. The methods include 3D solid parametric model generation, soil distribution using Cctree data structure, equipment fleet construction and equipment fleet operation. A simulation test is performed to verify the effectiveness of the equipment fleet management system in terms of equipment operating ratio, fuel usage, and $CO_2$ emission.

토공작업은 모든 종류의 토목공사에 기본이 되는 공종으로 공기, 공사비와 생산성에 영향을 미치는 요소이다. 토공은 그룹으로 형성된 다수의 건설장비들이 필요한 기계화 작업이며 건설장비로 인하여 많은 연료를 소비하는 작업이다. 그러나 일반적으로 토공작업은 건설장비 운전자의 경험과 직관에 의하여 수행되기 때문에 낮은 생산성, 높은 연료사용량 및 탄소를 많이 배출시킬 수 있는 문제점을 갖고 있다. 최근 연구에 의하면 이러한 문제점의 해결책의 하나로 건설장비 플릿관리 시스템이 제안되고 있다. 건설장비 플릿관리 시스템은 효과적인 토공계획, 최적의 건설장비 할당, 효율적인 건설장비 운영, 빠른 정보교환 등과 같은 기능을 수행한다. 본 연구에서는 건설장비 플릿관리 시스템 구축시 필요한 주요 방법론을 제시하는 것을 목적으로 하고 있다. 토공작업을 위한 3D 솔리드 파라메트릭 모델 형성, 옥트리를 이용한 토량배분, 건설장비 플릿구성 및 운영 방법론을 제시하였다. 건설장비 플릿관리 시스템의 효용성을 건설장비 가동률, 연료사용량, 이산화탄소 배출량 측면에서 검증해 보기 위하여 시뮬레이션을 실시하였다.
