Proper management of construction productivity is one of the main drivers of project success. This research focuses on the development of a construction productivity analysis system based on Web and OLAP in order to effectively manage construction productivity. Throughout the research effort, a construction productivity analysis system was modeled using IDEFO & ERD techniques and was deployed on the WWW(World Wide Web). Based on the system modeling, this research studies the methodology for system development of construction productivity that can consult the decision of managers on job site.

Most construction works in a building site are progressed by many work categories and sub-contractors. Therefore there are many difficult things of management of construction-information because variable occurrences are happened to manpower and material resources. For this reason, various management systems are suggested, but the application of these systems are difficult because only construction company manages these systems and sub-contractor's participation, understanding and financial ability are insufficient. In addition to that, there are other problems such as lost information when it is carried, perversion and distrust of information by hand and lots of time and labor are necessary for collection, analysis, and management of information which are offered for daily report. so the purpose of this study is for improvement of reporting process with making an analysis of productivity effects and an analysis of function and problem of daily report. I intend to suggest the direction of improved daily report system for better productivity of construction work through input information and management of cooperation enterprises.

양돈관리에 있어 생산성을 극대화하기 위한 방안을 살펴보면 첫째가 기록관리를 통한 생산성 분석, 둘째는 총산자수 향상을 위한 교배기술, 셋째는 효율적인 주간관리, 넷째는 임신진단을 통한 불임돈의 조기색출, 다섯째는 초산돈 관리와 분만후 5일 이내 자돈의 집중관리가 그것이다. 이 부분에서 총자산수 향상을 위한 교배기술은 무엇보다 중요하다. 특히 모돈에 있어서 이유후 재귀발정의 시기와 강도는 임신에 크나 큰 영향을 미친다. 다음에서 후보돈관리와 모돈관리, 웅돈관리 요령을 살펴보겠다.

Construction productivity is a key factor for efficiency evaluation of construction work process, project performance measurement, and basic data of work plan in construction industry. However, although construction productivity is important in construction industry, gathering methodology and analyzing methodology of productivity data are not well-organized therefore productivity data is not utilized in the construction industry The purpose of this study is to develop productivity prediction system using data mining technology based on activities and to suggest frameworks about productivity data collection, accumulation.

Despite the recognition of the need for productivity information and its importance, the feedback of productivity information is not well-established in the construction industry. Effective use of productivity information is required to improve the reliability of construction planning. However, in many cases, on-site productivity information is hardly management effectively, but rather it relies on the experience and/or intuition of project participants. Based on the literature review and expert interviews, the authors recognized that one of the possible solutions is to develop a systematic approach in dealing with productivity information of the construction job-sites. It is required that the new system should not be burdensome to users, purpose-oriented information management, easy-to follow information structure, real-time information feedback, and productivity-related factor recognition. Based on the preliminary investigations, this study proposed a framework for a novel system that facilitate the effective management of construction productivity information. This system has utilized Sketchup software which has good user accessibility by minimizing additional data input and related workload. The proposed system has been designed to input, process, and output the pertinent information through a four-stage process: preparation, input, processing, and output. The inputted construction information is classified into Task Breakdown Structure (TBS) and Material Breakdown Structure (MBS), which are constructed by referring to the contents of the standard specification of building construction, and converted into productivity information. In addition, the converted information is also graphically visualized on the screen, allowing the users to use the productivity information from the job-site. The productivity information management system proposed in this study has been pilot-tested in terms of practical applicability and information availability in the real construction project. Very positive results have been obtained from the usability and the applicability of the system and benefits are expected from the validity test of the system. If the proposed system is used in the planning stage in the construction, the productivity information and the continuous information is accumulated, the expected effectiveness of this study would be conceivably further enhanced.

기업 내 관련 업무 및 조직의 유기적 연결을 통한 원활한 정보의 흐름은 생산성의 증대에 많은 영향을 주며 기업의 경쟁력과도 밀접한 관계가 있다. 이러한 이유로 연구개발에서부터 설계, 제조, 판매에 이르기까지 컴퓨터와 통신기술을 활용하여 기업의 업무 흐름을 통합적으로 관리할 수 있는 컴퓨터 시스템이 필요하다. 그러나 기업 내 업무의 성격 및 규모, 어플리케이션 튜닝 등의 충분한 검토가 수행되지 않은 컴퓨팅 시스템은 개발비용의 부담과 더불어 시스템의 성능을 오히려 저하시킬 수 있다 본 논문은 생산 제조 업체의 업무의 성격과 환경에 적합하고 업무의 흐름을 유기적으로 통합 관리할 수 있는 클라이언트/서버 기반 생산 관리 시스템을 설계 및 구현하였다.

Korea's labor productivity in construction sites is dependent on experience and act in accordance with the human element of the construction workers. In order to increase the work productivity of the construction site that requires a strategic management to potentially hindrance factors of labor productivity. However, without considering the potential problems, management of labor productivity in prior studies is focused only on the immediate problems. The purpose of this study is to compare the site-specific analysis of labor productivity impediments using easy IPA to identify potential causes. As a result of the analysis was to identify the realistic problems of job insecurity and poor working conditions as well as economic problems. It is expected that it is possible to provide the basic data to strategy suggestions for long-term labor productivity improvement of the construction site.

Construction managers need to pay a close attention to the resource utilization in order to deliver the construction project successfully. Construction scheduling is crucial for resource control in that it provides information when and how much to bring down work force to sites. In scheduling, activity duration is projected based on the productivity of historical data or the intuition of scheduler. This paper studies the opportunity of applying cost-based productivity for estimating activity duration. For cost-based productivity, the cost of resource is used as an input and the work quantities as an output. Out of historical data, regression model has been developed to understand the validity of applying cost-based productivity in projecting activity duration. The result of study will work as a prerequisite for implementing the environment of database-based construction scheduling.

건설 프로젝트 관리의 주요한 목표는 계획된 시간 내에, 정해진 예산으로 규정된 목표(명세 또는 품질)를 확보하는 것이다. 국내 건설 산업은 타 산업 분야에 비하여 생산성이 매우 낮은 편이다. 이는 60년대 이후 급속한 개발 정책에 따른 부작용의 하나로, 하드웨어의 급속한 성장에 비하여 이를 관리하기 위한 소프트웨어의 개발이 부족했기 때문으로 풀이할 수 있다. 이에 본 연구에서는 건설 프로젝트의 생산성을 향상시키기 위한 노력의 일환으로 계획 단계에서의 실행과 완성 단계에서의 실행을 비교하여 이를 작업일보, 감독일지 등의 진도관리 자료를 활용하여 분석하여 건설 프로젝트의 실제적인 생산성 저하 요인을 도출하였다. 따라서 본 연구 결과는 현행 국내의 건설 프로젝트에 대한 사례분석을 통하여 실제적인 생산성 저하 요인을 분석한 것인 만큼 향후 건설 관리 기술의 향상에 많은 도움을 줄 수 있을 것으로 기대된다.
