Recent research has been ongoing for modular buildings in the country, and interest increases. However, in accordance with legal restrictions in the country with regard to Project Delivery system of Modular Building, the activation of modular buildings industry is obstructed. In Korea, in accordance with national contract law, the construction contract is apply to the project delivery system of modular buildings, and in accordance with Framework Act on the Construction Industry, The project delivery system of modular buildings has to be a separate order. The definition of separate order in contract as defined in the law is that the electric work and Communication work and digestion facility work has to be separate each contract in order to be ensured professionalism. In accordance with law, the project delivery system of modular buildings is that the contract for construction is concluded with the Owner and the Construction Contractor and the contract for goods is concluded with the construction Contractor and modular manufacturer. Due to these project delivery system, the domestic factory production rate when making a modular unit is significantly reduced compared to the rate of factory production abroad and the domestic factory production rate is estimated to 10-20%. Due to the factory production rate is also low, despite what can be done at the factory the workload in construction field increases. According to the workload in field increases, the effect of the schedule reduction can be reduced. It resolved to form a consortium with a modular manufacturer and construction companies or the contract is concluded with Owner, modular manufacturer and construction companies in each. In this paper, we propose a specific project delivery system for modular building to solve the problem of the low factory production rate and the problem of schedule reduction. Through this paper, due to the variety of project delivery system on modular buildings is expected to contribute to the activation of modular buildings.

Recently the construction of the ERP(Enterprise Resource Planning) system becomes accomplished actively from the many enterprises. But the many problems occur in acquisition of production data which is a fundamental data of system. Also to delay the acquisition of the production result is fatal in the efficient business operation. The construction of the POP(Point of Production) system which acquires production data at real time is become accomplished widely, In the POP system it is most important to acquire the production data which is accurate. But the many enterprises drop the competitive power with acquisition of the data which could not be trusted. In this paper, we analyze these causes and present the method which it can improve the reliability of production data. Also we introduce a real application case.

In this study, attempts to analyze the case study of production design were carried out through: 1) exploration of the factors influencing the interface between architectural and production design phases; 2)application of precast technologies. Building design and construction planning in Japan may be characterized by ample use of Production Design which extends over the whole projects phases. Taking a composite construction system for apartment buildings which allow for alternative combination of different technologies as a case study object, three projects have been chosen to analyze actual process of determining product sub-system and their specification. And the expectancies of this paper are that it can be used as efficient data for improvement of system to systematize Constructability(Buildability) in korea.

Standard production unit system has been used as accumulated standard for the cost estimation of public construction projects. However, it is difficult to estimate reasonable cost due to adaptation of a uniform standard and reflect changes in the technology. The purpose of this study is to provide basic data for improvement of standard production unit system through the identifying problems and analysing its influence on enactment and/or revision work of standard production unit system.

Objective of the research is to put the vast and complex fault tracking knowledge of human experts in semiconductor production line into the knowledge base of computer system. We mined the fault tracking knowledge of domain experts(engineers of production line) for the construction of knowledge base of the expert system. Object oriented fact models which increase the extensibility and reusability have been built. The rules are designed to perform the fault diagnosis of the items in production device. We have exploited the evidence accumulation method to assign check priority in rules. The major contribution is in the overall design and implementation of the nile base and related facts of the expert system in object oriented paradigm for the application of the system in fault diagnosis in semiconductor production line.

최근, OSC(Off-Site Construction)기반 PC구조의 활성화를 위한 제도적 기반 마련의 일환으로 적정공사비 산정에 필요한 품셈 개발을 요구받고 있다. PC공법의 공사비는 공장제작-운반-현장설치의 단계로 구성된다. 최근 운반과 현장 설치는 부재(subsidiary materials)별 현장실태 조사 결과를 반영한 표준품셈 체계(standard product calculation system)를 제시하는 등 관련 연구가 진행되고 있다(Lee et al., 2021). 반면, 공장 제작 공사비 산정과 관련된 연구는 전무한 실정이다. 본 연구에서는 PC 공법의 공장제작 공사비 산정기준 마련을 위해 공장 제작 환경에 활용할 수 있는 품셈 체계를 제시하였다. 이를 위해 시공절차에 따른 작업 공종을 도출하였으며, 공종별로 연계된 표준품셈을 분석하여 작업 특성에 적합한 표준 투입인력을 산출하였다. 품셈 체계는 PC부재의 현장설치와 동일하게 기둥, 보, 벽체, 슬래브 부재로 구성하였으며, 공종별 기능공을 기준으로 부재별 기본공수를 제시함으로서 직접노무비의 산출이 가능하도록 하였다. 또한, 개별 부재의 규격(m³)에 따라 생산성이 변화되는 특성을 고려하여 부재 크기를 품의 할증 요소로 제시하였다. 본 연구결과는 현재 견적에 의해 재료비료 계상되는 PC공법의 공장제작 비용을 객관적으로 검증할 수 토대 마련에 기여할 수 것이다.

표준품셈은 우리나라 건설공사에 있어 가장 기본적인 요소이지만, 표준품셈이 공동주택 건설공사에서 실제 투입 되는 노무량과 큰 차이를 나타내고 있다. 따라서 실적공사비방식에 의해 공사비를 산정하는 것이 합리적인 대안이 될 수 있으나 원가계산서상에 각종 경비 등에는 정확한 노무량을 파악하여야 비용이 산출될 것이며 공사 진도 관리를 위해 투입 노무량을 정확히 파악할 필요가 있다. 본 연구는 2000년 이후 준공 된 수도권에서 공동주택 건설공사에서 표준품셈과 실투입 노무량을 조사하여 비교한 결과 다음과 같은 결과를 얻을 수 있었다. 실제 투입 노무량은 조적공 1.184인/천매, 미장공 0.048인/$m^2$, 방수공 0.039인/$m^2$, 타일공 0.059인/$m^2$이다. 표준품셈 대비 투입율은 보면 조적공 59.8%, 미장공41.3%, 방수공 31.5%, 타일공 34.3%이다. 방수공의 투입 비율이 가장 낮고 조적공이 비교적 높았다. 따라서 우리나라 공동주택 건설공사의 노무량은 실적공사비를 토대로한 원가계산이 바람직하지만, 공사관리에서 노무량이 주요 변수인 만큼 실제에 근접한 표준품셈을 지속적인 보완이 필요할 것으로 보인다.
