Procurement and lifting scheduling of modules and resources in modular construction, where modules that are manufactured from factory are delivered and assembled on site, is a crucial factor that determines the efficiency of the whole construction. However, previous studies have barely acknowledged the significance of resource procurement process and lifting of modules in modular construction. Therefore, this research aims to derive factors that are in need of improvement for successful implementation of procurement and lifting efficiency, and visualize them according to their importance and performance on improvement through IPA(Important Performance Analysis).

RUP의 Unified Process Model 에는 Use-Case Model, Analysis Model, Design Model, Deployment Model, Implementation Model, Test Model의 6가지 모델이 있다. 이 모델들은 모두 일관성이 있다. 한 모델에서 나오는 요소들은 전, 후 단계에서 다른 모델들과 Trace Dependencies를 갖는다. 예를 들면, Use-Case Model에서는 한 Use Case는 Design Model에서 Use-Case Realization으로 Test Model에서는 Test Case로 Trace Dependencies를 갖는다. 소프트웨어 개발에서 추적성은 Understandability와 Change Propagation 과 같은 이유로 매우 중요하다. 그러나 RUP에서는 각 모델들간의 추적성에 대한 지침이 충분히 제시되어 있지 않아, 개발 과정중에 요구사항의 변경이나 에러 수정 또는 향후 관리 시에 어려움을 겪고 있다. 본 논문에서는 이 점에 중점을 두고 RUP에서 제시하고 있는 모델들 간의 추적성 중 설계모델에서 분석모델로의 추적성 적용지침을 제시한다.

The long-term purpose of Military Acquisition Program Management (MAPM) is to fulfill requested performance, budget, and timing of military capability building. The Defense Acquisition Program Administration was established in 2006 and it adopted Integrated Control System. Moreover, there have no much studies done to examine the condition of Defense Capability Improvement Project in Korea through an empirical research although there are sixty one organizations are operating currently under Defense Capability Improvement Project. The objective of this study is to recognize Military Acquisition Program Management as a single project and to critically review relationship between Critical Success Factors (CSF) and Military Acquisition Program Management. Accordingly, three determinants to lead to successful Military Acquisition Program Management are "Communication" "User Participation" and "User Requirement." This study also demonstrates that Critical Success Factors have distinctive influences on successful Military Acquisition Program Management based on characteristic, size and phase of project. In retrospect, it is meaningful that Integrated Project Team (IPT) could classify priority of management according to characteristic, size and phase of project in the course of implementation.

These days, Construction industries are getting bigger, more specialized and complicated. Accordingly, the items of management is increased, also owner's organization is reduced. For this reason, various a method of construction management is introduced in the domestic construction industry. But introduction of construction management have caused increase cost because role duplication of managers. This role duplication is caused by confusion of trial and error, irrationality of system. And every construction project have peculiar properties, also owner's organization of project have various properties. This various properties is not reflected in the construction management , and the regimental method of construction management applied. In order to solving these problems, this study suggested the commissioning model for CM service reflected the properties of project and owner. This study have to selection of the critical service, service item of construction management and definition of owner's role through analysis of the properties of project, owner's capacity and requirement.

인터넷 이용의 급증에 따라 전자상거래(Electronic Commerce)가 시간적, 공간적 제약을 극복한 새로운 경제활동으로 지식, 정보기반시대의 새로운 패러다임으로 국가 경제, 사회의 변혁을 주도하는 수단으로 부각되고 있다. 이러한 시대적 환경과 인터넷 이용의 확산으로 전자상거래 시장규모도 이례 없이 증가하고 있다. 특히 전자상거래에 대비하는 대부분의 업체들이 내세우는 전략의 공통점은 B2C(Business to Customer) 보다는 B2B(Business to Business)에 중점을 두고 있다는 것이다. 기업간 전자상거래에 필수적인 요소로 부각되고 있는 워크플로우 관리 시스템이 서로 다른 벤더들에 의해 제작된 워크플로우 엔진들의 상호운영성이 보장되지 않기 때문에 전자상거래의 제 기능을 발휘하지 못한다. 본 논문에서는 서로 다른 벤더들에 의해 제작된 워크플로우 엔진들의 상호운영성을 위한 기본 명세에 대해 살펴보기로 한다. 또한 엄청난 비즈니스 프로세스로 구성되어 있는 기업간 전자상거래 상에서의 통합된 비즈니스 프로세스를 정의하기 위한 워크플로우 정의도구 구현 시 고려해야 할 사항들에 대해서 살펴보기로 한다.

The purpose of this study is to efficiency scheme to design VE through the case studies of construction VE forapartments. The adapted research method includes five case studies of construction VE and analysis of constructionVE practice. The results of this study are as follows 1) For efficiency of design VE, data management system whichis necessary for construction VE database establishment and its application were proposed. 2) Through workingsystem improvement of construction VE, an improvement to design VE performance process was proposed. 3)Consideration factors and main VE items for efficient design VE item selection of apartment buildings wereproposed.

The modular construction means that more than 70% of the parts such as walls, windows, electrical wiring, facility piping, bathrooms, and kitchen appliances are pre-assembled at the factory and transported to the site. It is possible to shorten the construction period than general construction work and to secure high quality through modular mass production since the modular construction works in the field at the same time as the modular production. However, there are only four domestic modular manufacturers, and each company's modular components and construction methods are different, so it is necessary to standardize them. Therefore, this study investigated the construction process centering on the stacking method of modular housing construction work applied to D site in Cheonan-si, and proposed the key points of quality management by construction stage. As the project was conducted as a pilot project for government R&D projects, some differences may occur from general modular housing construction. However, the construction process and quality control focus of each unit box type modular house analyzed in this study can be used as basic data in the future of modular housing construction. In addition, the results of this study can be used to establish construction standards, such as the development of checklists and establishment of standard processes.

This study suggests for effective operation of systematic analysis method for human factors which is based on the requirement architecture framework a requirement process to manage requirements for improvement is discussed, such as in requirements generation, database construction, management of experimental design, and management of the design traceability. For the objectives, we analyzed the method construct of the starting point views of user requirement which is adopted the requirement architecture concept to cover the whole activities required to do and the human factors guidelines and standards are suggested for verification and validation of the develop requirements. It is getting more attention as the operation of the enabling systems goes up these days. Throughout the propose of this study, human factors requirement database design presented in operational environment system for enabling system which is based on case study using a computer aided se tool. This study will be contributed to how the operational requirement database for the enabling system and operational human factors can be constructed in an integrated system design fashion.

In Korea, demand for the Social Overhead Capital(SOC) projects has tremendously increased since 1970's and is expected to keep growing to support national economic development as well as to enhance the quality of life. In these projects, project planning and feasibility study phase is one of the most critical phases because it determines the success of later phases. However, we have experienced trial and errors repeatedly such as cost overruns and schedule delays in many of the SOC projects. These problems can be prevented or at least expected in the earlier phase and it requires well-developed and standardized project planning process and systems before design, procurement, and construction phases begin. Therefore, the purpose of this research is to investigate current problems in this phase and provide framework for a model for the project planning management which can be used for the SOC projects to insure the whole project success.
