This paper proposes the method to develop information system for maintenance of urban transit. We have to develop the standard information system, but have difficult to get user's requirement. To solve this problem, we propose the method, web-based, component-based, and prototype-based development method. Proposed method may provide a procedure to develop information system that have hard to get user's requirement.

최근 정보기술은 여러 산업분야에 접목되어 보이지 않는 많은 효과를 창출하고 있다. 건설분야에서도 이러한 정보기술을 통한 정보화가 단계적으로 진행되고 있다. 유지관리 분야는 건설 제 단계 중 관심 및 중요도가 점차 고조되고 있는 분야로 시설물의 공용기간동안 체계적인 관리기법을 도입하여 생애주기비용을 최소화하며, 시설물의 기능을 향상시키려는 유지관리 주체들의 분주한 움직임이 한창이다. 본 연구는 이러한 주변환경에 부합하여 가장 효율적인 시설물 유지관리 정보시스템을 도입하기 위한 방향을 수립하는데 주요 초점을 두었다. 따라서 본 연구에서는 먼저, 대상시설물을 선정하고 시설물별 유지관리 주체들에 대한 환경 및 현황분석을 실시한 후 그 결과에 입각한 정보시스템 도입방향을 제시하였다. 기존의 유지관리 관린 정보시스템의 문제점을 보완하고, 유지관리. 주체의 실무자들이 직접 수행하는 유지관리 관련 업무를 개선할 수 있는 방안을 도출하고자 하였다.

기존의 철도교량 유지관리체계는 주로 정보누락, 문서위주 관리 및 유선기반의 정보수집 등으로 인하여 다양한 현장의 환경변화에 실시간 대응이 곤란하여 능동적인 철도교량 유지관리 전략 수립에 제약을 갖고 있다. 본 연구에서는 유비쿼터스 기반의 철도교량 유지관리 정보운용체계 구축을 위한 실무 활용모형과 건설 생애주기의 통합 정보관리체계인 BIM (Building Information Modeling) 개념을 적용하여 유지관리 통합 운용모형을 제안하고 있다. 이의 개발 및 실무적 적용의 타당성 확보를 위해 설문분석에 의한 정량적 평가를 수행하였다. 최근 철도교량의 지능형 유지관리 운영체계가 확대될 것을 고려하면, 본 연구의 제안사항은 운영체계 구축을 위한 통합 프레임워크로 활용될 수 있을 것이다.

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.

Vessel PMS (Planned Maintenance System) is a paper and/or software based system to monitor vessel engine equipment including main propulsion, steering, auxiliary machinery and cargo handling information. This is one of mandatory survey for vessel introduced by IMO (International Maritime Organization). The planned maintenance as well as documentation must be performed according to a system to be approved by classification agencies. Recently, vessel owners have preferred software based systems to collect and preserve accurate data. However, not ship specific and not taking into account the user are said by end users as operational difficulties. To relieve these concerns, this research analyzes vessel PMS data, suggests a middleware to support automatic collection and design consideration of user interface.

Digitalization of not only non-safety but also safety-grade I &C systems with full computerized Main Control Room (MCR) is the recent trend of I&C systems of nuclear power plants (NPP) around the world, while plant maintenance has been shifting from traditional time based maintenance to condition based maintenance. In order to cope with the new trend of operation and maintenance in NPP, a concept of online distributed diagnostic system for both plant operation and maintenance has been proposed in order to further improve both the plant efficiency and the work environment of plant operation staff members by organizational learning. In this respect, the research subjects of human machine interface (HMI) for the online distributed diagnostic system are also discussed for supporting the plant personnel at both MCR and local working places in the plant by the application of advanced ICT (Information and Communication Technologies).

In construction of high speed railway, the fan shape is limited to achieve reduction of required travel time and concrete railway which has structural stability and induces small maintenance cost with allowable ground settlement is recently applied. So construction of concrete railway on soft ground in which considerable ground settlement occurs increases and settlement management in soft ground section is required. Field monitoring on ground movement and integrated geotechnical information system which manages construction, design, and field monitoring data are essential for settlement management of concrete railway subgrade. Site investigation data are also required due to future repair work. Therefore in this study, integrated geotechnical information system for construction and maintenance of concrete railway is developed. The developed system consists of a database and an application program. The database contains site investigation, construction, design, and field monitoring data throughout a railway. Application program performs various functions on managing and utilizing information in the database with graphic visualization of output. And by providing integrating information with comprehensible visual displays, the applicability and effectiveness of the developed system for construction and maintenance management were confirmed.

Recently, many kinds of research has been actively developing for a standardization and information related to the construction works. These works include the general field of design, construction, supervision, maintenance and management on facilities. The works of database construction for a standardization and information were chiefly propelled centering around the present conditions related to the design, construction work. The field related to maintenance and management on facilities lags behind in the works of database construction. The establishment of standard classification system(SCS) on facilities and inspection data is most important among the things related to maintenance and management to have a efficiently maintenance and management. This paper suggests SCS on facilities and inspection data according to that of facilities. On the basis of SCS of facilities and inspection data, code work with classification system and input work for a data of maintenance and management was practised. The purpose of this paper is to suggest a kind of statistics data and investigate a characteristics of inspection using statistic data on tunnel structures
