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.

In Korea, it has recently occurred that problems of productivity and construction duration in the construction industry. If five days per week system come into effect, they'll become more urgent. The productivity of construction industry and competitive construction duration in Korea are too low. If post sale system becomes effective, construction companies will strive to improve productivity. Therefore, the objective of this study is to draw up Architectural PC as the alternative for productivity improving and analyze possibility of productivity improving by comparing with established method of construction.

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.

In Korea, five days per week system, duration reduction bidding system, and post sale system have recently stimulated an interest in productivity improvement in construction project. However, analysis result of productivity in Korean construction industry found that the productivity is too low. APC (Architectural PC) is alternative of reveal wall and parapet in apartment housing prcjects and is used abroad broadly because of duration reduction for productivity improving. APC is used as external curtain wall in Dubai, North America, and Southeast Asia. Therefore, it is proposed that necessary to Introduce APC in Korea. The objective of this study is to draw up introduction of APC in apartment housing projects. We analysed the feasibility of the use of APC. The survey results reported that APC would be able to improve the productivity in the eight productivity factors.

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.
