  • Urban renewal projects, in the form of mega-projects, are being actively implemented both nationally and internationally to revitalize inactive cities. These programs, however, are difficult to manage efficiently due to their need for a large budget over a long period of time and due to conflicts with stockholders. Moreover, existing cost and duration management systems are structured with emphasis on the design and construction stage of unit projects, thus limiting their application to long-term mega-projects that are integrated with various facilities. To solve these problems, this study developed a web-based system that can collectively manage the cost and duration of mega-projects at a program level. The unit modules included in the system--CBS organization, construction cost and duration prediction, and total cost and duration prediction--can support decision-making at the early stage of the program. Furthermore, the modules, which include contract management, execution management, change management, and program progress management, support the program operations for its successful accomplishment. The web-based cost and duration management system developed in this study is expected to be used as a valuable tool that supports the successful accomplishment of mega-projects through their efficient management throughout their life cycle.

  • A number of urban renewal projects are currently being implemented around the world. Current project management tools are limited in effectively dealing with numerous issues regarding management of these projects (e.g., simultaneous execution of multiple projects). As an effort to address this deficiency, an Intelligent Program Management Information System (i-PgMIS) was developed for effective management of urban renewal projects. The i-PgMIS is a web-based system consisting of various modules including cost management, schedule management, risk management, change management, eco-value engineering (EVE) and so on. Based on the recognition of increasing awareness of creating sustainable built environment, this paper focuses on the EVE module that can support eco-value analysis at program-level management. The EVE module is expected to enhance value and sustainability of construction processes throughout the whole 'program' lifecycle and further to support program feasibility study based on life cycle costing.

  • According to relevant laws, in the case of a construction project with a total construction cost of 30 billion won or more, a post-construction evaluation must be performed after completion. In addition, a post-construction evaluation report must be prepared and entered into the Continuous Acquisition & Life-cycle Support(CALS). As a result of reviewing the currently accumulated post-construction evaluation reports, since the report is not standardized, it is difficult for public project owners to write the report. It also hinders the post-construction evaluation and management center from verifying contents, analyzing data, and deriving meaningful results. In order to improve the convenience of the public owners who must conduct post-construction evaluations and the work efficiency of the center, evaluation factors were standardized and a standard post-construction evaluation report format for road construction was developed in Excel. Through this, the data in the reports will be effectively accumulated, managed, and analyzed, so that meaningful results will be produced and be helpful in future construction work.

  • RIMS(Rolling Stock Information Maintenance System) was installed in structure which it can analyze the data base in need of credibility maintenance. So it could accumulate real data without repulsion of working spot. Information system was installed not following to system but following to working spot. The development of RIMS project was started from March 29, 2001 and it has been operating from October 12, 2004 in Chang-dong Car depot for light maintenance in charge subway line4. So substantial data base was accumulated for three years. This study calculated all RAMS data by analyzing data base accumulated in RIMS and used in dada base about credibility maintenance and found investigation of propriety, expectation of the life cycle cost, the improvement plan on credibility of sorts of cars and formation about the cycle of repairing and maintenance. This got MKBSF MKBF and MTBF about devices and sorts of line4 Rolling Stocks for it.

  • 최근 낙후된 도심 재개발을 목적으로 신도시 및 신시가지 위주의 도시재생을 위한 프로젝트가 진행되고 있다. 이러한 도시재생 프로젝트들은 매우 다양한 기능을 요구하므로, 현존하는 단일 프로젝트 단계의 프로젝트 관리 시스템을 적용하기에는 한계점을 갖는다. 특히, 도심이라는 한정된 공간에서 다양한 도시기반시설을 입체화하고 다양한 용도를 복합화하는 복잡한 배경과 함께, 참여 주체들 간의 복잡한 이해관계, 민간 및 공공 개발영역의 혼재, 운영유지 및 자산관리의 어려움 등의 문제점이 제기되고 있다. 그러므로, 본 연구에서는 다음의 두 가지 목적을 달성하고자 한다. 1) 수평, 수직적인 공간내 다양한 시설이 입체적으로 배치되는 메가프로젝트에 적합한 새로운 프로그램 관리 시스템 Prototype Ver 1.0의 개발, 2) 동시다발적으로 진행되는 다양한 프로젝트의 종합적인 관리가 가능한 프로그램 수준의 관리 체계 Prototype Ver 1.0의 수립. 효율적인 연구수행을 위해 지능형 종합 사업관리시스템 개발, 생애주기단계별 업무 프로세스 최적화 및 표준화 개발, 사업 전(全)단계를 고려한 종합사업비 및 공정관리 기술개발, 종합사업관리 효율화 및 최적화 기술개발 등의 세부 과제로 이루어져 있으며, 메가프로젝트 생애주기의 최적화, 다양한 위험요소에 대한 대응 및 예측방안, 비용/공정/프로세스의 관리 및 예측방안, 웹기반의 새로운 iPMIS를 제시하고자 한다.

  • Railway fields are complicatedly connected with engineering such as physics, civil engineering, architecture engineering, electrical engineering (Telecommunication, signal, catenary, system), machine engineering and performance phase of project in domestic railway can be divided with four steps : planning, design, supervision, construction. Value Engineering is needed to reduce the cost of long period construction duration and periodically maintenance. Currently, railway design is difficult to act optimum design due to limited time, short of manpower, downsized of design company. therefore, VE concept in Design must require In order to solve this problem. it is called Design Management. This paper presents both item of design management and total design management tool of practical aspects, and describes LCC (Life Cycle Cost) analyze process and accomplishment process for applying VE concept

  • This study focus on what methods of MOT are needed and utilized to solve a technical problem in the MOT leading company. We first classified the MOT methods by project life cycle and R&D job quality based on the several discussion with working group. In order to study, the survey was carried out by 168 experts working on MOT practices. Our main research findings are as follows. The level of utilized MOT methods was above average because MOT sector was beginning to represent an increasing share of total R&D business. But the satisfaction level on the MOT majors was below average. The more utilized MOT methods in practices were 'environment analysis and opportunity research,' 'business feasibility,' 'roadmapping,' 'portfolio,' 'technology tree,' 'scheduling,' 'risk management,' 'six sigma,' 'design of experiment,' 'quality control,' 'cost analysis' etc. And the subjects of product realization process were also needed to MOT practice such as 'design for reliability,' 'design for cost,' 'design for performance,' 'design for safety' deeply involved to product quality. Finally, the capability requested to University students were 'problem define and solving,' 'technology planning and strategy,' 'creative thinking.'
