  • The importance of the air and vessel traffic control center is increasing rapidly after the recent accident of 'Sewol ferry'. Aviation, marine, and the logistics sectors are already using monitoring and control technology widely. However, the monitoring and control system for complex and dangerous construction sites operation has yet to be employed. A monitoring/control system is required for effective communication between the control center and the construction equipment fleet at a construction site, and also the exact role that notifies accurate process and identification of hazards on construction sites as needed. Therefore, this paper presents the study about communication between the construction equipment fleet and the control center through the comparison of air traffic, marine, and logistics control systems for the development of construction equipment fleet management system.

  • Construction industry is facing difficult challenges in terms of productivity, manpower, and industrial accidents. Currently, along with the 4th Industrial Revolution, various high-tech technologies are emerging, and efforts are being made to solve the problem by applying the technologies related to the 4th Industrial Revolution to the construction industry. As part of these efforts, research is being conducted to develop a construction equipment control system to increase productivity and safety at earthworks sites where many and various types of construction equipment are involved, and the system needs a function to increase productivity by optimizing the moving path of construction equipment. In the case of trucks, the location of the temporary road must be optimized in order to optimize the path of movement in the construction site. However, only matters related to the quality standard of temporary roads have been suggested so far, and there is no standardized process for efficiently determining the location of temporary roads. In this paper, the factors and its importance related to the location of the temporary road were identified through field surveys and interviews with experts, and a method for determining the location of the temporary road was presented. It was confirmed that the suggested method through a case study could improve the productivity of earthwork.

  • Along with the emergence of technologies related to the 4th industrial revolution, all industry sectors are making efforts to dramatically increase productivity by actively introducing high-tech technologies. Recently, the MLIT (Ministry of Land, Infrastructure and Transport) is trying to solve problems related to low productivity and high accident rate in the construction industry by applying the 4th industrial revolution technologies to infrastructure construction through smart construction R&D projects. This research was performed as part of the smart construction R&D project supported by MLIT, and the purpose is to develop a module that automatically generates moving paths for construction equipment based on the earthwork plan for road construction. The generated moving path can be used to provide safe and efficient paths for construction equipment and to support MC and MG to work efficiently. The moving paths for construction equipment are created based on the Visibility Graph and a case study is performed to show how the paths are generated based on a given construction site.

  • With the advent of the 4th industrial revolution and the combination of IoT, there have been diverse domestic and foreign researches for the development of construction industry. Especially, in the large-scale earthwork site where many and various construction equipments are put into, the control system between construction equipments is important for the increase of productivity. Thus, after developing the fleet management system for the optimum operation of construction equipments, the problems were checked and improved for each step in the process of application at site. In order to verify the site application process of the fleet management system for the optimum operation of construction equipments, the analysis on the productivity was performed by inputting the data used for the actual site and the site data using this system and then comparing the data through simulation. The analysis was limited to excavator and dump. In the results of the analysis, the rate of work per hour was increased to the range of 4 % while the cost price was decreased to 4 %. Even though the results of the analysis could be different depending on the site applied, the results showing the increase of workload of equipments and the decrease of cost price in the complex project at earthwork site verify the increase of productivity.

  • 가스터빈, 워터제트 등 기존의 추진시스템을 이용한 초고속선의 핵심기술 등을 종합하여 중형 화물선은 일본 TSL 수준에 도달시키고 중간목표로 설정한 선박의 실용화를 단계적으로 추진 하며, 선형기술, 선체 구조기술, 추진시스템기술, 원자력 안전기술, 해상 교통관제기술 등 이에 필요한 기술을 개발한다. 이들 기술은 21세기에 걸맞는 최첨단 기술이 될 것이다. 선박개발과 병행하여 초고속 선박의 운항과 조화를 이루는 고속 하역설비를 갖춘 항만시설의 개발도 함께 추진되어야 할 것이다. 초고속 해상 물류체계의 구축을 위해서는 수송 수단인 선박뿐만 아니라 항만, 하역시스템의 고속 현대화가 필요하다. 그러므로 초고속 선박과 접안, 하역이 가능한 전 용항만의 설계와 개발을 위해서는 이에 관련된 국내의 공공연구기관들과 SOC 관련 엔지니어 링사, 조선사 등 민간기업의 참여로 추진해야할 것이다. 또한 원자력 추진선 개발을 위해서는 선박용 원자로 및 연료기술이 필요하므로 원자력영구소와 미국의 참여로 공동개발하며, 상대국 에도 전용 항구가 필요하므로 해당국가간의 협약에 의해 하역장비, 운한 안전기술 등을 개발하고 건설하는 등 국제 컨소시엄의 구성이 바람직하다. 다만 기술개발의 성공과 핵심기술의 확보를 위하여 우리나라가 Initiative를 장악할 필요가 있다고 판단된다.
