The Eco-performance assessment program was developed as part of Eco-performance management for buildings at the national level in developed countries. Cases of domestic Green Building Certification(GBC) system was developed but these program's destination of Eco-performance management for buildings needs systematic management by the limited GBC. Generally in the construction industry, Eco-performance management of Building Life-cycle is required. Therefore this paper develop the creation of Eco-performance information and management process, those are from design and maintenance management phases, through suggest the development of a information management for Eco-performance management of buildings. In addition, it makes to decrease the reproduction of information unnecessarily by analyzation of the related association between the information of facilities objects and Eco-performance management. Finally, study the previous reaserch and suggest the BIM by the method of information management and this paper purpose the development of web-based Eco BIM object library management system.

The second half of the 20th century was marked with a significant raise in amount of railway bridges in Austria made of reinforced concrete. Today, many of these bridges are slowly approaching the end of their envisaged service life. Current methodology of assessment and evaluation of structural condition is based on visual inspections, which, due to its subjectivity, can lead to delayed interventions, irreparable damages and additional costs. Thus, to support engineers in the process of structural evaluation and prediction of the remaining service life, the Austrian Federal Railways (${\ddot{O}}$ BB) commissioned the formation of a concept for an anticipatory life cycle management of engineering structures. The part concerning concrete bridges consisted of forming a bridge management system (BMS) in a form of a web-based analysis tool, known as the LeCIE_tool. Contrary to most BMSs, where prediction of a condition is based on Markovian models, in the LeCIE_tool, the time-dependent deterioration mechanisms of chloride- and carbonation-induced corrosion are used as the most common deterioration processes in transportation infrastructure. Hence, the main aim of this article is to describe the background of the introduced tool, with a discussion on exposure classes and crucial parameters of chloride ingress and carbonation models. Moreover, the article presents a verification of the generated analysis tool through service life prediction on a dozen of bridges of the Austrian railway network, as well as a case study with a more detailed description and implementation of the concept applied.

It is very important to rationally allocate manufacturing processes because customer's needs are being various, and product life cycle in the market Is being shortened. The process allocation is needed before making process control plan and is mostly being done by the field experience or intuition of machine operator, process engineer and/or maintenance technician. Therefore, a modified allocation method using the process variation is proposed. This paper presents the result of comparative studies between current method and the proposed one.

동시공학적 개념을 선박의 설계에 적용하기 위하여 동시공학 지원 시스템을 구축하는 방법을 제시함이 이 연구의 목적이다. Intranet기술의 개방성과 경제성을 이용한 시스템 개발은 조선 산업의 특성에 맞는 지원체계를 구축하는데 합리적인 대안으로 여겨진다. 그간의 동시공학 적용노력인 단위 시스템의 개발을 통한 방식에서 벗어나 정보시스템과 통합을 가능하게 하는 Intranet 방식은 설계와 생산, Life-cycle정보의 통합을 가능하게 해주는 Framework을 제공해 줄 수 있다. 동시공학 지원 시스템의 주요기능의 파악과 필요한 요소기술들의 경향분석을 이 연구의 주내용으로 하고 있다. 가상 설계의 기능, 동시공학 팀의 Workflow, 의사소통 지원, 데이타베이스 검색, 관리, 타시스템 연계, 설계 데이타 view등이 주요 필요 기능으로 여겨진다.

The objectives of this paper are to provide software developer selection criteria and to develop evaluation framework using AHP (Analytic Hierarchy Process). The selection criteria are extracted from Software Development Life Cycle, Quality Assurance, and Productivitiy of Organization. In this paper, the selection model is proposed and its examples are illustrated. Though some further research is required, the proposed model can be regarded as a basis of a DSS for the selection of the software developer.

In order to find out the customer requirements and to develop new products more effectively, the Kano model and QFD(Quality Function Deployment), AHP(Analytic Hierarchy Process) developed and applied. But, Many companies difficult to select the CTQ(Critical to Quality) of new product. Especially the life cycle of cell phone is very short. In this thesis, the Kano model and AHP(Analytic Hierarchy Process) for finding the CTQ(Critical to Quality) for customer satisfaction are suggested. It is explained and discussed with the example of cell phone.

As technological change Is accelerated and product life cycle Is getting shorter. Industry and market are newly being made. Therefore company. Industry and government are requested foy developing technology Planning method in response to the change effectively. Roadmap is usually used to one of the technology Planning methods. This study reviews previous studios related to roadmap's presentation and roadmapplng.

In this paper, we introduce IEC 60300(Dependability program management) into urban transit system, and propose effective method to apply IEC 60300 to Subway Corporation. The dependability is the collective term used to describe the availability performance and its influencing factors such as reliability performance, maintainability performance and maintenance support performance. A dependability program covers all phases of a system's life cycle from planning to operation and possibly disposal, and is composed of program elements divided into tasks.

Most software reliability models and other methods attempt to estimate some measures based on its fault history. There are several phases of the software life cycle including testing phase. We can propose it's stopping rule to decide when to stop the testing and pass it on to the next phase by considering the detailed structure of software and calculating the failure rate when each fault was detected. Downs (1985) proposed a method which was developed for estimating the failure rate applicable only to two-level profiles. In this paper, I extended to profiles involving more levels.

In this paper, Internet based ship technical information management system has been developed as a means to accumulate, manage, share and utilize various distributed applications and information used for ship design and building. The information managed in the system are data from whole life cycle including concept design, basic design, detailed design, construction, operation and maintenance. In addition, using the developed system, integrated system framework is also proposed to integrate applications and database in concurrent engineering environment.
