Today, the power utilities is setting on the slow load growth and the aging of power equipment, and then could spend the efforts on the stability of system performance. Asset management may be defined as the process of maximizing corporate profit by maximizing performance and minimizing cost over the entire life cycle of power equipment. Therefore, asset management is great way to fulfill the economic investment and the stability of system performance. This paper presents the application of effective asset managem ent from an economic perspective. A proposed method is considering the life cycle analysis using life cycle cost methodology for hydro-generator during the total life cycle. The life cycle cost methodology include a way to calculating maintenance and operating costs. The proposed method will be expected to play an important role in investment decision making considering economic evaluation.

This paper is concerned with the life-cycle cost(LCC) of the urban transit system which was developed by KRRI and is now under test in Gyeongsan, Korea. Its reliability, availability and maintainability(RAM) were analyzed. LCC is the core part of analyzing the total cost of acquisition and ownership of a system. LCC analysis of a system is the most effective when it is applied in the it's early design phase. In this paper, we present IEC 60300-3-3(Life Cycle Costing) in detail and propose how to apply LCC in assessing the urban transit system according to RAM process. This case study demonstrates that reliability management system is very effective in reducing the operating cost of subway corporations in Korea.

Due to the development of modern technology and the enlargement of industrial scale, the scale of many projects is expanding and the complexity is also increasing. Individual management of existing projects cannot effectively manage projects in this trend, and it is necessary to systematically manage the entire process from initiation to completion. Accordingly, the need for integrated management and life cycle management that can efficiently manage the entire project is emerging, and for this, a systematic project management system is also required. PMS enables efficient project management by linking business processes such as resource, schedule, scope, and output management of a project with separately separated infrastructure accordingly. In this paper, a research model was proposed to manage the project from the perspective of implementing integrated management and life cycle management, especially during R&D project execution, and to prove the mediating role between PMS and R&D project performance for this purpose. The proposed research model will be able to help companies and organizations that feel the need to implement integrated management and life cycle management and are preparing to build a PMS-type system or that have already been established to efficiently perform project management.

Time management is one of the critical tasks in project management. Based on the theories of total quality management, this authors presented a project time management method, total time management (TTM), so as to facilitate highway project time management. This paper discussed the four fundamental characteristics of TTM: total factors management, staff management, project life cycle management, and Plan-Do-Check-Action (PDCA) cycle management. Now, most managers use computer software to manage the project. In order to make the theory of TTM more executable, the authors develop a project time management system suitable for TTM. This paper presents this time management system's analysis processes including system requirement, key functions etc..

The main purpose of Korea Space Launch Vehicle II(KSLV-II) Program is to develop a domestic launch vehicle that can deliver a 1.5ton class application satellite into a Low Earth Orbit(600~800km). The data management is an essential factor in systems engineering for success of large-scale complex systems development, and it systematically manages the information and technical data for the total life-cycle of a system. In this paper, data management policies and processes on KSLV-II program are presented, and product life-cycle management system for KSLV-II program is also presented.

유지관리 분야는 다른 단계에 비해서 법과 제도가 미비하고, 관계기관 및 건축주가 이에 대한 대비가 충분하지 못하여 건축물의 수명이 물리적인 수명에 훨씬 미치지 못하는 경우가 많이 발생하고 있다. 또한 건설제단계의 Life-cycle을 고려하면 전체 공용수명 중 유지관리단계가 전체의 $70\%$가량을 점유하고 있어서 건설산업의 합리화를 위에서 유지관리에 대한 관리체계의 정립이 필요하다. 그리고 현재 운용 중인 유지관리 시스템은 주로 하자발생시 이를 처리하는 하자대응시스템으로 운영되고 있으며, 다른 단계와의 정보 공유는 낮은 수준에서 이루어지고 있다. 공동주택을 비롯한 건축물과 관련된 우리나라의 기존 제도, 법규 및 정책 등은 신규 건설시장에 초점이 맞추어져 있어서, 기존 시설물을 효율적으로 관리하기 위한 체계는 아직 제대로 정비되어 있지 않고 있다. 따라서 본 연구에서는 공공시설물의 효율적인 $운영\cdot관리\cdot활용$을 위하여 공공시설물 유지관리 체계의 현황을 분석하여 시스템의 구축방향을 제시하며, 나아가 정부주도로 구축되고 있는 건설정보 시스템을 구축에 대응하여, 현행 유지관리 정보시스템의 발전방향과 개선방향을 제시하고자 한다.

국가연구개발사업은 시장실패를 교정하기 위한 정부정책 구현에 있어서 매우 중요한 활동이며 최근 재정규모의 확대로 인해 성과평가에 대한 중요성과 더불어 효율적인 관리체계 구축에 대한 논의가 진행되는 분야이다. 본 연구는 이러한 국가연구개발사업에 대해 전주기 관리방안을 모색하기 위한 탐색 연구이다. 체계적인 논의에 있어서 관리체계에 대한 사항을 사전평가의 관점을 중심으로 살펴보았다. 국외 사례와 국내 제도의 비교를 통해 현행 국가연구개발사업의 수명주기 관리와 관련하여 제도차원의 고려사항을 도출했고 국가연구개발사업의 사전분석에 대한 사례 자료를 수집하고 분석을 수행하였다. 이를 통해 현재 제도상의 문제점을 구체화하였으며 향후 국가연구개발사업의 전주기적 관리를 효과적으로 적용하기 위해서 연구개발 정부지출의 범주화와 지출성격에 따른 관리체계 이원화가 필요함을 제시하였다.

정보 및 정보를 생산, 처리, 폐기하는 시스템은 정보의 총수명주기에 걸쳐 일정수준의 보안이 유지되어야 한다. 일정수준의 보안을 유지하기 위해 소프트웨어 및 자동차 개발, 미국 연방정부 정보체계 등 시스템 수명주기의 보안관리 프로세스를 적용하고 있으나, 우리나라에는 이와 유사한 보안관리 프로세스가 전무한 실정이다. 본 논문에서는 국방 분야 정보 및 정보 처리시스템의 총수명주기에 걸쳐 일정수준의 보안을 유지하기 위한 한국형 보안위험관리 프레임워크를 제안한다. 국방 분야에 적용할 수 있는 한국형 보안위험관리 프레임워크의 개발 목적과 적용방안을 소개함으로써 향후 국방 보안업무가 나가야 할 방향을 제시하고 보안 패러다임의 전환을 유도하고자 한다

Systemic management is required at each phase of the C4I system life cycle to achieve information advantage in the battlefield through stable operation of the C4I system under the NCOE. In particular, the maintenance phase is the longest period of the C4I system life cycle, and it is easy to utilize and analyze data such as faults that occur during system operation. However, according to the previous research, the maintenance is evaluated as a phase in which the definition and management of comprehensive indicators are insufficient compared to other phase. In this paper, we propose the method of C4I Maintenance Priority decision using Maintenance metric. As a result of modifying the Naval Tactical C4I System's preventive maintenance cycle according to the priority, the total number of faults is reduced and the maintenance efficiency is improved.

In these days of world-wide business environment, the characteristics of quality management are variety, specialty, decentralization, totality, etc. Thus nowadays quality management is demanded to incorporate these new concepts. We propose a web-bused distributed expert system for this purpose. The system consists of four expert systems for design of experiment, acceptance inspection, statistical process control and reliability management corresponding to design quality, incoming-material quality, manufacturing quality and usability quality, respectively, throughout the total product life cycle. Each distributed expert system at the horizontal level in the hierarchy carries out its own quality jobs independently. At the lower level in the hierarchy there is an expert system for measurement analysis to provide reliable data, and at the upper level, an expert system for total quality management to coordinate, integrate and make final decisions. A prototype has been developed and its application is presented.
