NC 공작기계가 생산현장에 도입된 이래 이를 Computer와 연결함으로써 CAD/CAM/CAE의 결합이 실현되어가고 있다. 최근에는 CAD/CAM/CAE와 더불어 생산공정에 있었서 여러 대의 NC공작기계, 로보트, 운송장치를 결합하고 공구관리나 생산관리까지도 Computer를 이용하고자 하는 소위 CIM(Computer Intergrated Manufacturing)시스템에 관한 연구가 활발히 진행되고 있으며 여기에 생산가공 시스템의 상태 변화량의 감지를 통하여 공정상태를 종합적으로 감시, 진단할 수 있는 시스템(M & D : Monitoring and Diagnosis)에 대한 필요성도 증대되고 있다. 이는 생산 공정에 있어서의 궁극적 과제인 생산 자동화 혹은 무인 자동화의 가능성을 한층 높여준다.

축산(양계) 기자재는 축산의 꽃이라 할수 있지만 자동화, 규모화가 이미 진행된 상태에서 사양관리에 익숙해져 버린 대다수의 사양가 분들은 그 중요성을 인식하지 못하는 것 같다. 즉, 산업이 발전함과 더불어 우리 축산업도 비약적으로 발달한데에는 축산기자개가 한몫을 했다고 해도 과언은 아닐 것이다. 특히 사계절이 뚜렷한 우리나라에서는 기자재 생산에 있어서도 생산하시는 분들은 하나하나 세밀히 살피고 따져서 과학적인 생산에 임하는 자세로 대처해 나가야 하겠다. 농장(양계장)에서는 여름철의 생산성이 년간 경영에 막대한 영향을 미치고 있은 것이 사실이다. 우리나라의 여름철 기후는 열대성 고기압의 영향을 받아 우기(장마)를 동반한 고온다습한 환경으로 기자재를 생산하는 데에도 반영을 시켜 생산이 이루어져야하겠으며, 급이기 생산에서도 마찬가지라 생각한다. 그러므로 생산성을 향상시키기 위한 방법들은 다방면에서 모색되겠지만 하절기 농가들의 사료 품질관리에 있어서 벌크통, 사료라인, 급이기의 사용방법의 원칙 지키기가 지켜지지가 않아 더위로 인한 생활환경에서의 스트레스와 그로인한 사료의 급여는 동물들의 영양보충에 어려움이 많다

To complete various types of finish works with higher quality in much less time, TACT, which was mostly used for high-rise buildings, has been adapted to meet the needs for systematic schedule management in construction sites. However, the effectiveness of adapting TACT has not been shown as expected due to the different perspectives on productivity from both general contractor and subcontractors based on unforeseen conditions according to the types of site. Furthermore, not enough theoretical backgrounds, empirical data, and systematic approaches to solve the fundamental problems caused by each participants' different views on productivity has produced obstacles for establishing effective solutions. Therefore, this research aims to analyze the possible main reasons for having different point of views regarding productivity among various participants of residential building sites using TACT based on literature review, site survey, and interviews. Also, case study was conducted to propose obtainable productivity (OP) regression equation and productivity achievement ratio (PAR) with reduction factors (RFs) and actual productivity (AP) data from an actual construction site. The proposed outcome may assist general contractors converting output management with PPC to productivity management with actual data using PAR. On the other hand, subcontractors would be able to estimate theory-based maximum productivity of construction sites with TACT by using OP. The PAR will enhance the communication between general and sub-contractors for their decision making process. Finally, the main RFs derived from PAR could be used as essential keys for productivity management to increase the economical and operational effectiveness of the construction project.

Recent new town construction project proouced large numbers of apartment houses using precast concrete (P. C.) panels. l'bst construction companies involved in this project put their management focus on to the individual control of P.C. panel producing plants and the job sites. Little attention was paid to the integrated management of the production. transportation. and im;tallation of P. C. panels. Numerous job site delays experienced in the new town project were largely based on the poor coordination between these three key disciplines of the P. C. apartment construction. This stlldy was initiated with an .intention to improve coordination between these disciplines. Activities of these disciplines were identified and related data were gathered. This was performed through the interv:iews with the personnel involved in P. C. constructlon and through the analy::;is of the related documents and publications. Based on this information. the authors are nolol developing a model IoIhich will provide a foundation for opt:iJnal.ly coorc.inated control of the proouction. transportation, and installation of P. C. panels for apartment construction. In this paper. the authors briefly present intermediate results of this study.

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.

채란계의 생산성향상은 실용계의 유전적인 생산능력의 개량과 환경 및 사양관리 기술의 개선에 의하여 이루어 질 수 있는데 아무리 사양관리를 잘하여도 그 닭이 가지고 있는 유전적인 생산능력이 좋지 못할 경우 소기의 목적을 달성할 수 없으므로 채란계 산업의 성공적인 경영을 위해서는 생산성이 높은 우수한 계종을 선택하여야 한다. (중략)

We analyzed the questionnaire survey for the current maintenance of Incheon port's loading and unloading equipments and the possibility of TPM(Total Productive Maintenance) application. And also, We certificated Structural Equation Model with computer packages. Results of the survey indicated that the current maintenance of Incheon port's loading and unloading equipments was not good. We recognized the relationship of contextual factors about the productivity of the loading and unloading equipments The productivity of the loading and unloading equipment positively depends on maintenance management of equipments, but the organization and personnel management does not have a influence on the productivity of the loading and unloading equipment. So we suggest TPM as the future maintenance methodology of equipments. Using TPM to the loading and unloading equipments, we will try to improve the methodology of the organization and personnel management.

중소기업의 기술혁신은 제품의 생산성을 높임으로써 궁극적으로는 새로운 영역에의 참여와 고용창출 효과를 가져올 뿐만 아니라 국가의 수출경쟁력에 이바지하는 기여도가 매우 높다. 중소기업은 규모가 작고 유기적인 조직구조의 특성상 탄력적으로 기술혁신에 대처할 수 있는 유리한 면이 있지만, 국내의 중소기업 기술혁신은 매우 열악한 상태이다. 따라서 대기업을 위주로 형성되어 있는 통합생산관리시스템(CIM)의 개념을 도입하고 산업용네트워크와 통합생산관리시스템을 적용하는 중소기업 기술혁신의 추진전략에 대해 설명하였다.

To reform and improve the productivity of construction industry, 1) it should be encouraged to improve the construction production process and 2) it is required to enhance reliability of construction information based on the systematic thinking process. To promote the information reliability created during construction production process, Lean Construction Research Center(LRC2) is developing a supporting system to improve design/material supply/schedule management, functioning to efficiently manage the information created at construction production processes and developing a web based construction information system that provides result management/decision making support/knowledge based information services.
