  • This paper represents a study on disassembly sequence generation system for automobile parts. This system is practically very useful because proper disassembly sequence of end-of-life product becomes crucial as take-back obligations are imposed for environmental reasons. Therefore a disassembly sequence generation system is suggested to automatically derive all the feasible disassembly sequences from the assembly modeling files. As a result, in consideration of the all parts and subassemblies the optimum disassembly sequence is generated. And the optimum disassembly sequence for a certain part or subassembly can be also suggested.

  • This study was conducted basic research for introduction plan of building dismantlement to reduce construction waste fundamentally and efficiently. The current domestic and overseas legislations relation with dismantlement were compared. In addition, the difference of construction waste treatment and pure demolition cost that were applied to dismantlement and general deconstruction method in building were compared. The total cost that was estimated to apply dismantlement in building was higher about 6% than that of general deconstruction.

  • 자동차 폐차사업자들은 대부분 소규모로 영세하게 운영되고 있으며, 비효율적인 폐차 프로세스로 인해 폐차 소유자는 물론 폐차처리장까지 불이익을 받고 있다. 이를 위한 폐차 시스템에 대한 연구가 국내외에서 활발히 진행되고 있다. 하지만 기존에 개발되어진 폐차 해체시스템의 경우는 국내 폐차업계에 적용하기에는 경제적, 실용적으로 현실성이 부족하다. 따라서 본 연구에서는 폐차에 대한 효율성 극대화와 범용성 확보를 위해 시뮬레이션을 통한 폐자동차 해체시스템을 개발하고자 한다. 시뮬레이션을 통한 폐차 해체시스템의 사용은 복잡한 공정 또는 시스템의 설계 및 운영결과에 대한 효율적 분석이 가능하며, 다양한 위치 및 작업내용을 변경시켜 여러 대안을 마련할 수 있고, 이에 대한 결과를 미리 알아봄으로써 적은 시간과 비용으로 현장상황에 맞는 적절한 시스템을 구축할 수 있게 해주는 장점이 있다. 또한 최적 해체경로 시스템의 적용으로 시스템의 효율을 향상시켰다. 개발되어질 시스템은 높은 범용성 및 유연성 확보로 국내 폐차 업계의 발전에 크게 이바지 할 것이다.

  • Currently, one of the most interested things at home and abroad country will be an eco-friendly construction. Among these, one of the most important elements will be the recycle and reuse of construction and demolition waste. Because construction waste is generated the most at the demolition phase, it is important to minimize the quantity of the demolition waste at the phase. And it is also important to develop a system to manage rightly the generated demolition waste. But in the domestic country, a research for this has hardly been carried out. In recent, the government has realized its importance and is making a research to improve demolition technique and is preparing a research to make a raw for deconstruction. Therefore, this study examined its application situation and importance by analyzing the trend of demolition technique used in the domestic industry. Also this study carried out a survey for situation analysis of the demolition industry. This study suggested items needed for the development of demolition technique, demolition design and reduction of C&D waste through a survey results and a situation analysis.

  • Now, one of the greatest concerns at home and abroad is eco-friendly construction. Above all, the reduce and recycle of the construction waste may be one of the most important things. The construction waste has been produced most at demolition phase, but the research into that area has not being to make nearly within the country. Recently, as the government have realized the importance of that area, they are making research to improve traditional demolition methods. Also, they are preparing to make a raw to enforce deconstruction during demolition phase. This research has analyzed the problems and waste types which produced during the demolition works by surveying in site. Until now, in the interior, the right quantity basis has not been suggested, because of the absence of any methods to estimate it accurately. Therefore, this study has compared and analyzed owner's ordering quantity, drawing analysis quantity with measuring the waste to produced at site during demolition works, this research results are expected to be the important materials for future research into the construction waste area.

  • Domestic explosive demolition techniques have been developed and applied for low-rise structures up to now. However, the demand for the development of those techniques that can be applied economically, safely and environment-friendly rapidly increases because the old high-rise RC rahmen structures that were built since around 1970s are now required to rebuild. As a result, element technologies of explosive demolition for low-rise structures were applied to take advantage of technology in high-rise structures that performed application testing at Chungang Department demolition field in Daejeon city. It could judge elements technology establishment for high-rise structure demolition and field application and suggest the improvements when the problems occurred to develop High-rise building demolition techniques for method of protection a field test and the dust reduction test. The water cannon test was applied to reduce the dust site and the drilling tests are performed to select the best components for explosives demolition elements techniques of the reliability. This paper shows that we have the ability to remove a high-rise building using environmentally friendly safe and economical explosives demolition method. It would contribute to prevent a foreign company from entering the domestic market and should contribute to acquire competitiveness of domestic demolition industry.
