A movement for higher productivity is very important of the basis for industry society prosperity. Contineous productivity improvement have a right understanding of a conception of productivity and its effect that are removed an act before the trouble of higher productivity enforcement. It is that the theoretical principle of productivity improvement are harmonized of the stage of application, actual problems and considered a special characteristic of the enterprise in industry for contineous productivity improvement. A movement for higher productivity is used by way of a welfare society.

As the recent economic downturn continues to undermine the profits of construction industry in Korea, it has become ever more pressing to improve productivity of the industry. Since construction site management manpower staffing plan has close bearing on the productivity of construction projects, it is essential to estimate and mobilize adequate number of resources as per conditions and characteristics of each construction site. However, there are no reference approaches in practice to provide baseline for site management manpower staffing plan or estimation of manpower requirement. Therefore, this study aims to examine factors affecting productivity that warrants first and foremost consideration in development of site management manpower staffing plan during the initial phase of building construction project by conducting survey on industry stakehoders with hands-on responsibilities in construction sites and analyzing their responses. Conclusions herein will provide basic inputs for subsequent studies on development of site management manpower staffing plan as per project characteristics.

While Korean construction companies are adapting themselves to rapidly changing business landscape at home and abroad, intensifying competition among competitors in local as well as global market deteriorates the profitability of construction industry, which leads to another problem. In response to such challenges, many construction companies continue to innovate their business portfolio and organization structure, with strong commitment to business process innovation. Furthermore, they need to analyze the productivity of project site management manpower overhauling business processes systematically and develop effective alternative strategies. This research aims to analyze the productivity of project site management manpower. Current operational practices of construction site organizations have been analyzed with focus on large construction companies in Korea and data gathered from project sites have been analyzed from a wide range of perspectives, In so doing, this research is expected to provide basic inputs for any subsequent attempt to estimate proper resource requirement for site management tasks in construction projects and analyze the management productivity of such resources by enabling construction companies to better understand the current operational status of site organization.

국내 건설산업에서 생산성 정보는 중요성과 그 기능에도 불구하고 생산성 데이터의 수집 및 분석 방법이 체계화되어 있지 못하다. 또한 생산성 관리는 대부분 현장관리자의 경험과 직관에 의존하고 있으며 생산성 데이터를 공사계획 및 관리에 적극 활용하지 못하고 있는 상황이다. 따라서 본 연구에서는 공동주택 마감공사의 생산성 예측 및 생산성 영향요인을 분석할 수 있는 기반을 마련하기 위해 단위작업별 생산성 관련 데이터를 수집하여 딥러닝 기반의 생산성 예측모델을 개발하고자 한다. 연구결과인 딥러닝 기반의 공동주택 단위작업별 생산성 예측모델은 신뢰할 수 있는 생산성 정보 데이터에 딥러닝을 적용하여 향후 데이터가 축적될수록 발전되는 기술로 공동주택 프로젝트 관리시스템의 기본 모듈이 될 수 있다. 또한 과거 유사한 프로젝트의 생산성 데이터를 통한 개산견적, 공정계획을 위한 작업일수 산정, 투입인원 산정 등과 같은 프로젝트 엔지니어링 과정에 활용 가능하며 공사 진행 중 예측과 다른 생산성 발견 시 원인 분석에 용이하여 신속한 대응 및 향후 예방이 가능할 것으로 기대된다.

Purpose: The purpose of this study was to analyze the results of the productivity innovation partnership program and propose the method for improvement. We investigated 90 companies which are sub-contractors of Samsung Electronics, LG electronics, POSCO and so on. Methods: We developed and carried out a survey and analyzed the results of the program. The interviews are also performed. Results: This study shows that the partnership program is a effective method for improving quality and productivity of sub-contractors and it is necessary to extend coverage of this program. Conclusion: We suggested some improvement points of the partnership program and they are to be applied in the next year. The results show that the suggestion is helpful and valuable.

This paper proposes a strategic model of linkage between productivity metrics and financial accounting metrics to properly evaluate the financial effect of TPM activities and the business performance. This linkage strategy provides a connection tool for clear communication between factory-level and headquarters that the metrics proposed by this paper ultimately improves a quality of support from the management by receiving the factors required for productivity activities in the practical field. This factor includes such as equipment, raw materials and labors. Here, we propose that chain reaction models using break down structure of productivity metrics and financial metrics enhance the knowledge sharing of KPI (Key Performance Indicator) which generally tend to create oversimplified communication between management in headquarters and employees in the practical fields. The productivity metrics include OEE(Overall Equipment Effectiveness) of TPM (Total Productive Maintenance), OLE (Overall Labor Effectiveness) of PAC(Performance and Analysis and Control) activities, and OYE (Overall Yield Effectiveness) of TMM(Total Material Management) activities. The financial accounting metrics include ROE(Return on Equity), ROA(Return on Asset), and AVR(Added-Value Rate). The suggested chain reaction model selects the financial metrics as initial stage and branch down until final stage of productivity metrics. When demand exceeds supply, an ideal speed rate, the lean OEE strategy can be initially applied to reduce the gap between the demand and supply, then apply variable costing to estimate correct amount of operating profit. In addition, the paper presents a new type of model for linkage between financial accounting metrics including CAPEX(Capital Expenditure), OPEX(Operating Expenditure), EVA(Economic Added Value), DCL(Degree of Combined Leverage), and TPM productivity activities including AM(Autonomous Maintenance), PM(Preventive Maintenance), MP(Maintenance Prevention) and QM(Quality Maintenance). In order to support the evidence of proposed linkage strategy, a case analysis on 52 projects from national TPM contest from 2011 to 2012 is analyzed. The case presents the classification of CAPEX and OPEX activities from TPM, and proposes the correct implementation of financial effect for TPM projects.

글로벌 시대인 현재의 산업사회는 점차 고도화, 첨단화의 경쟁사회로 발전되어 가고 있다. 이러한 현실에서 산업 형태를 불문하고 생산성의 풍요성은 날로 증대되고 있다. 뿐만 아니라 생산성의 향상은 최근 국내 현실이 겪고 있는 경제적 위기 상황을 극복하기 위해, 그리고 국제 산업 환경에서 경쟁력을 확보하기 위해 모든 산업 분야가 추구하여야 할 방향이기도 하다. 따라서 최근 어려움을 겪고 있는 국내 건설산업의 경우도 생산성 향상의 중요성은 절실히 필요하다. 본 논문은 하도급자를 대상으로 설문을 통한 분석을 토대로 건설생산성에 미치는 향상요인에 대한 책임을 분석한다. 이로 인해 저해요인들의 개선해야할 우선 순위를 알 수 있는 기초 자료로 볼 수 있다.

This study empirically analyze efficiency and productivity changes of public hospitals of Korea using data envelopment analysis/Window model and global Malmquist indices model. We use the ten-year data from 2001 to 2010 of 30 regional public hospitals listed database from the Association of Korean Regional Public Hospitals. The main focuses are to reveal whether the technical inefficiency are improved as time goes by, and efficiency and productivity are affected by environmental factors. The results can be summarized as follows. First, the efficiencies of public hospitals rise in trend as time passes. Second, regional public hospitals show the different average efficiencies according to their regional type, hospital type, operational type, medicaid type, and demand and supply conditions by Mann-Whitney U-tests. Third, technical efficiency changes mainly contribute to 4.4% annual average growth rate of productivity of regional public hospitals during that period. Our findings have some policy implications. It is confirmed that there exist some environmental inefficiencies, and those inefficiencies can not be overcome through just improving the inner management system. Thus, policy and institutional changes are necessary for regional public hospitals to improve efficiency and productivity overall.
