  • Usually, processing whole project or a part of frame work delays due to acceleration, changing orders, management, characters of project. overtime, worker crowding, early occupation in the field of construction. Through a whole project, these factors cause decreasing construction labor-productivity which is the most dependent in business of construction. These kind of decreasing of construction labor-productivity cause many negative effects, just as extension of time, increasing cost in project of construction. Regardless of characters of construction or decreasing labor-productivity, extension of time is a incident which needs acceleration, also it cause a high possibility of claim and dispute. The productivity has just a broad meaning in business of construction. That's why it's difficult to apply in the field of construction. Especially, factors increasing or decreasing labor-productivity is defined by analysis of working as qualitative and outlined evaluation. However, study of the each factor decreasing construction labor-productivity analysis has not researched, because of difficulty of systematic measurement and management. The existed studies about management of productivity are just focused on estimation of productivity, not on evaluation of productivity. It was true that I couldn't examine clearly about the analysis of how much important per each the factor which have influence on labor-productivity because of the characteristic as qualitative that the labor productivity have On this study, i tried to get the factors decreasing of labor- productivity with gathering opinions of panels of expert's studies about the factors decreasing of labor-productivity on project of construction through Delphi method and i evaluated the result factors as quantitatively and subjectively about importance of factors decreasing construction labor-productivity Analysis, using AHP Method by Saaty. Also, using Delphi and AHP method, 1 suggest substantiated method qualitative factors are measured by quantitative criteria.

  • This study measures the relationship between labor productivity and national competitiveness. Through the shift- share analysis method, the paper has separated labor productivity into three factors: static shift effect, dynamic shift effect and endogeneous effect. Next, in combination with the Granger causality test, the paper examines the relationship between the factors constituting labor productivity and competitiveness during the period from 2005 to 2017. Research data is collected from General Statistics Office and annual global competitiveness reports. The results show that the interaction between labor productivity with global competitiveness index (GCI) in Vietnam has similar variation. Nevertheless, when separating labor productivity into three effects, this relationship shows more clearly that the impact of labor productivity on GCI scores is mainly caused by endogeneous effect, not by static shift effect or dynamic shift effect. Therefore, in order to improve its competitiveness, Vietnam should focus on a number of solutions: reforming the education system towards developing thinking capacity and creative capacity; fostering industrial manners to create dynamic and flexible workers; building the State with sufficient capacity to implement consistent and transparent policies; formulating policies to attract all economic sectors so that they actively participate in the field of human resource training for the country.

  • Labor productivity issues within the construction industry are receiving increasing attention. With the improvement in the standard of living, domestic laborers are avoiding 3D(Difficult, Dirty, and Dangerous) jobs by degrees. Because of this situation, the problem of insufficient labor is exacerbating in several basic industries. In particular, insufficient labor is a serious problem in the construction sector, where the workers are ageing and labor costs are increasing. In this study, we adopt a systematic approach to identify factors that influence labor productivity and analyze the causality between the factors and their ripple effects with the aim that the results of the study will help improve labor productivity and ensure its effective management. The established labor productivity model using systems thinking will get a footing in the greatest strategy in the construction industry.

  • Given the characteristics of construction work, which is highly dependent on labor compared to other industries, management of labor productivity is closely related with the construction industry. Therefore, it has become more important than ever to boost productivity in construction projects. The present study used a survey of form workers to conduct correlation analysis between factors of working tools, musculoskeletal disorders, and labor productivity. In addition, using structural equation modeling and the Sobel model, the study verified the mediating effects of musculoskeletal disorders. The findings of the analysis showed that friction sawing cutters are related with waist/back musculoskeletal disorders. In the relation between working tools and labor productivity, the hammer showed a strong positive relationship with Productivity1, standing out as the tool with the highest correlation. In the relation between musculoskeletal disorders and labor, hands/wrists showed a significant correlation with Productivity 1. The test result on the mediating effects of musculoskeletal disorders derived a statistically significant value, at Z=1.215 (p<0.05), suggesting that musculoskeletal disorders have mediating effects in the relation between working tools and labor productivity. Through this study, we identified relationships among factors related to labor productivity in construction sites; the findings of this study could be used as basic data regarding factors adversely affecting labor productivity, as well as to determine how to improve labor productivity strategically.

  • Purpose - This study examines the effects of expatriate transfer on foreign affiliate's labor productivity. Design/methodology - Using Korean-owned foreign affiliate-level data, we estimate the effect of expatriate transfer on foreign affiliate's labor productivity using the system generalized method of moments model. We also consider foreign affiliate- and host country-specific contingencies and test how they are associated with expatriates in enhancing foreign affiliate's labor productivity. Findings - We consider foreign production intensity and cultural distance between the home (i.e., South Korea) and host countries as key contingencies that influence the effect of expatriates on foreign affiliate's labor productivity. We find that expatriates are effective in enhancing the labor productivity of less production-intensive foreign affiliates. This effect is strengthened as expatriates are deployed to countries that share cultural similarities with the home country. Originality/value - Considering that previous studies provide mixed results on the effect of expatriates, our findings suggest that foreign affiliate-specific operational orientation and cultural distance should be considered jointly to understand the true effect of expatriate staffing on foreign affiliate performance.

  • Compared to its building construction work, the percentage of labor cost of residential fire protection system construction is relatively high. Over 50 percent of the total project costs are allocated to the labor cost in installing fire protection systems. Thus, it is critical to improve labor productivity by effective resource allocation in order for cost reduction and quality control. The main purpose of this study is to analyze the labor productivity for installing residential fire protection systems. To achieve the study goal, three construction sites were comparatively analyzed in terms of labor productivity of different work types based on the daily work report and quantity takeoff worksheet. These work types include sprinkler, sleeve, and fire piping installation. By computing labor productivity of different work types, the actual productivity of each work type was compared to the quantity required by the standards of construction estimate (Poomsaem). In addition, important factors that affect labor productivity were also identified by analyzing various project characteristics with ANOVA test. The results of the study showed that sprinkler installation requires the highest number of workers than any other work types. This study ultimately contribute to the basis for effective resource allocation plan and scheduling management in residental fire protection system construction.
