  • 1970년대 고도 성장시기를 거치면서 단시간 내에 많은 양의 제품을 생산하는 것이 회사의 자랑거리일 때가 있었다. 작업환경이나 작업자의 안전에 대한 의식은 제품의 빠른 생산이라는 사명에 가려 대수롭지 않게 여겼고, 생산현장에서 재해가 발생할 경우 늦게라도 회사가 안전에 더 신경을 쓰는 것이 아니라 오히려 사고를 당한 당사자의 부주의를 탓하던 시절이었다. 그러나, 시대가 변하고 교육과 생활수준이 향상되면서 작업환경 개선 및 안전의 중요성을 인식하게 되었고, 그에 대한 규정도 선진국 수준으로 강화 되었다.

  • DNC의 개념은 광범위하여 좁게는 컴퓨터와 CNC 기계간의 데이타 통신으로부터 넓게는 생산라인의 무인화, 공정관리 시스템에 까지 이른다. 우리 나라의 금형공장 현장의 현실은 선진국의 금형생산 시스템의 개념과 우리의 금형생산 시스템의 개념에서 상이한 부분의 상당수 발생하고 있어서 효과적인 공작기계용 데이터 통신망 구성에 많은 어려움이 있다.

  • 로봇의 어원은“로보타(Robota)"로 체코의 유명극작가 카렐차펙이 1920년에 쓴 희곡에서 처음 소개되었으며, 이는 체코어로 "강제적 노동 또는 노예"를 뜻한다. 로봇의 생산은 1980년대부터 본격적으로 시작되었으며, 2000년까지는 주로 산업현장에서 용접, 도장, 조립과 같은 작업을 수행하는 산업용 로봇이 생산되었다. 이들 로봇은 사람이라면 쉽게 지치거나 부주의해지기 쉬운 단순 반복작업을 고정된 위치에서 지정된 작업을 반복적으로 수행하도록 설계되어 사람보다 더 빠르고 정밀하게 일을 수행함으로써 생산성 향상에 중요한 역할을 담당하였다.

  • The field organization management in construction industry is very important factor improvement and cost reduction. But, until now, evaluation methods on the existing field organization did not make ready and endeavor of organization betterment was insufficient in construction industry. The purpose of this study to provide basic data for reasonable selection and evaluation of the field manager through analyzing operation status of the existing field organization in apartment and office building project by interview and questionnaire on the 22 construction companies. This study presented optimal proposal on the selection and evalution of field manager for productivity improvement and cost reduction by means of efficient construction progress in apartment and dffice building project.

  • Nuclear power plant projects are being increased all over the world. The construction of nuclear power plants needs huge money and time, which makes conducting a detailed analysis of productivity through the whole process. Reinforced-concrete works productivity field data was collected for more than one year and analyzed from a nuclear-power-plant project in Korea. The productivities of formwork, rebar-work, and concrete pouring were $0.54m^2/man{\cdot}day$, $0.06ton/man{\cdot}day$, $1.98m^3/man{\cdot}day$, respectively. Moreover, it is revealed that 'Day of the Week' is a driver of the formwork activity and 'Overtime' is for all of the three. The results will be a great interest of industry personnel estimating time and cost of a new nuclear power plant.

  • The domestic construction market started to expand steadily since 1970s. The building market which utilizes a sandwich panel with advantages of economical construction expenses and convenient construction has grown rapidly in recent years. However, the companies which specialize in constructing sandwich panels are relatively small or medium size, compared with other construction companies. As a result, studies on the improvement of productivity have not been conducted sufficiently. In this study, the construction sites of sandwich panel are investigated, and the work processes by each team are analyzed. Additionally, the productivity and the construction cost of each construction team are analyzed by constructing a model using the Web-Cyclone. It is expected that the results of this study can be applied to estimate the productivity and the construction cost of a sandwich panel construction that is appropriate for the on-site characteristics of small and medium sized construction companies in Korea. Also, similar processes can be simulated based on the modeling constructed in this study.

  • The objectives of this study were to identify engineering problems in the design and installation of cable logging operation that affects productivity through case study of actual logging sites, and to analyze associated productivity loss and increased cost. As a result of the study, when the geographic conditions and engineering safety of the site are not sufficiently considered, deflection of the cable line can not be secured. Hourly productivity of the operation decreased to 65% and the logging cost increased by more than two times compared to the productive yarding operation, which lowered overall efficiency of the operation. Thus, it is required to spread filed technologies that minimize unnecessary production cost incurred due to the in-efficient logging operations as well as secure work safety and efficiency to expand cable logging operation throughout the country.

  • The importance of process improvement under construction has arisen from recent issue, lower productivity in the construction site. The various 3D modeling program is utilized in the procedure of construction as an alternative solution. However, it's still shortage of the consideration about a specific technical application. The purpose of the study in this paper is helpful to improve the productivity of construction site using 3D realization of constructing place as one of extensive modeling technologies, which leads to not only efficient management of construction site allowing people to check the real time situation in the place but also the revitalization of information flow about building process control and prgress, Therefore, I research into modeling algorithm and extensive construction site realization technology. 3D realization of building place would reduce the safety concerns by providing the real time information about construction site, and it could help to access easily to similar project through collecting and appling the database of sites. Furthermore it can be an opportunity to develop the procedure of production in construction industry and to upgrade the image of this field.
