Improving productivity in industries is a very critical issue, and improving labor productivity is especially important in construction industry, which is a labor-intensive industry. However, researches on labor productivity in construction industry are insufficient, and most of previous studies have limitations in terms of specificity and logic. In this study, fuzzy DEMATEL method was used to structural analyze of influence factors for labor productivity in construction industry based on previous researches and expert survey. The result of this study contributes to deriving priorities for improving labor productivity.

최근 국내 건설 산업에서 생산성과 건설공기 측면에서 문제점이 드러나고 있으며 또한, 국내 건설 산업의 생산성과 공기 경쟁력이 선진국에 비해 매우 낮은 것으로 분석되었다. 여기에 주5일 근무제가 시행된다면 문제는 더 심각해진다. 또한, 현재 입법 예고된 후분양제도가 실행된다면 건설사 입장에서는 공기 단축을 위한 생산성 향상이 건설업의 생사가 달린 일이다. 이에 본 연구에서는 생산성 향상을 위한 방안으로 PC의 한 종류인 건축 외관용 PC를 제시하고, 건축 외관용 PC를 사용하는 방안을 기존의 공법과 비교를 통해 생산성이 향상 되는가를 분석하고자 한다.

It is critical that all companies improve productivity in order to maintain their international competitiveness. The productivity can be explained as a measurement of effectiveness that is calculated by "the ratio of what is produced to what is required to produce it". The goal of this paper is to enhance productivity for a small fast food company mainly through work analysis. This work analysis will help the company to downsize by improving efficiency via motion analysis and by reduction of losses via facility improvement.provement.

Korean industries have been tend to depending upon historical information to control risk. The other hand, foreign industries have been identify risk factors using system safety techniques to predict future risk. One agency or person could not solve the problems of total safety system for improving productivity. In order to solve those problems, the production-safety group is necessary, and safety control system must be adapted by fitting to the production flow. This paper is present the methodology of driving occupational safety programs to increase productivity.

The purpose of a man-machine chart is improved utilization of a man or a machine. Improved utilization can mean less idle time, rebalanced idle time, or less idle time of an excessive component. In this study we improved the productivity of the assembly line in the electronics company using man-machine chart. The results are applicable for improving the effectiveness of line balancing problems in the electronics industry.

최근 주5일 근무제도, 공기 단축형 입찰제도와 후분양제도의 도입과 같은 제도적 변화로 건설공사에서 생산성 향상에 대한 관심이 증대되고 있다. 그러나 국내 건설 산업의 생산성은 선진국에 비해 현저히 낮은 것으로 지적되고 있다. 현재 초고층 공사가 활발히 이루어지고 있는 두바이 및 북미, 동남아시아 등지에서는 외부 커튼월로 건축 외관용 PC (Architectural PC)가 사용되고 있다. 이는 국내 공동주택 공사에서의 외부 날개벽, 수벽 및 파라페트 등의 외벽 마감을 대체하는 것으로 공기 단축 등의 생산성 향상 효과를 인정받아 해외에서 널리 사용되고 있다. 이에 본 연구에서는 국내 공동주택 공사에서 건축외관용 PC 도입을 제안하고, 건축 외관용 PC 활용에 따라 생산성 향상이 가능한지를 검증하였다. 설문 결과 공동주택의 외벽 마감에 건축 외관용 PC를 사용하였을 때 기존 공동주택 공사보다 생산성 측면에서 우수하다고 분석되었다.

For the continuous development of the manufacturing company, selp-helpㆍdiligence of the individual members of the organization and cooperation system of the sub-department process of the manufacture must operate under rationality. Moreover, perpetual and reasonable improvement on productivity should be focused on. Improvement on productivity implies raising $\ulcorner$output / input$\lrcorner$ ratio, and this does not only implies simple increase of the level of output. Therefore under the theoretical principle, Which is designed to increase the ratio of $\ulcorner$output / input$\lrcorner$ -economically select the relevant $\ulcorner$methodology$\lrcorner$. When rational improvement on productivity $\ulcorner$techniques$\lrcorner$ are properly applied with this methodology, calculated result will come out. The ultimate aim of improving quality does not mean simply reducing the percentage of the defects, but means improving the quality of products, for customer satisfaction. Thus recognize this, we have to contribute to the national economy growth through the enhancement of added value of individual company by $\ulcorner$improvement on quality and productivity, and reduction of the cost$\lrcorner$, $\ulcorner$improvement program on quality and productivity$\lrcorner$ shouldn't be just the parading formality. We can expect the economy result, these are applied to the learning essence and the principle of the improvement.

This paper considers a six sigma project for improving productivity of the brace complement center pillar. The project follows a disciplined process of fife phases: define, measure, analyze, improve, and control. A process map is used to identify process input and output variables. Eleven key process input variables are selected by using X&Y matrix and FMEA, and finally eight vital few input variables are selected from analyze phase. The optimum process conditions of the vital few input variables are jointly obtained by maximizing productivity of the brace complement center pillar using DOE and alternative selection method.

Safety of workers and productivity in construction site are affected according to the conflict status of work spaces which are performed at a time. The interference among the work spaces in construction site should be minimized because it becomes a blocking factor that causes construction delay and low productivity. Those factors can be managed by reasonable H&S (Health & Safety) practice. This research suggests the requirements of H&S practice and rules to establish the strategy of H&S management based on the literature reviews related to H&S rule. The suggested H&S rule can be visualized for searching space conflict point if the rule is linked with visual simulation tool. Accordingly the research results can be used for improving and visualizing construction productivity by work space control in 4D/nD CAD system.

This study compared the labor productivity of the construction industry to the manufacturing and service industries. In addition, It analyzed the construction labor productivity gap of the G7 countries based on data from the Korean Productivity Center. A comparative analysis of construction labor productivity between manufacturing and service industries, based on statistics from the National Statistical Office, revealed a relatively low level and trend of continued decline. In addition, a comparative analysis of the productivity of construction workers in the major G7 countries found that the difference in productivity is very large, with an average of 65.3 %. Therefore, domestic construction companies and the government should prepare Improvement measures to improve productivity by investing in technology development to increase labor productivity and improving the production system of the construction industry.
