공공건축물의 예산은 앞으로 유지관리에 더 많이 투입될 것으로 예상되며 체계적인 유지관리와 충분한 예산확보가 중요하게 인식되고 있다. 국내 건축물 유지관리는 인력 부족과 전문성 결여, 유지관리 예산산정의 근거부족으로 인하여 체계적인 유지관리가 이루어지지 않고 있다. 호주에서는 자산관리를 통해 시설물의 유지관리를 최적화하고 있으나, 국내의 경우 규제중심의 수동적인 형태를 벗어나지 못하고 있는 실정이다. 국내 유지관리의 선진화를 위해서 체계적인 자산관리의 도입이 필요하다. 이 연구에서는 국내 외 사회기반시설물에 적용한 자산관리 프로세스를 분석하고, 공공건축물의 자산관리 프레임워크를 제시하였다. 자산관리 절차는 일상적인 자산관리 절차에 선택적으로 자산 가치를 평가 하도록 구성되어 있다. 본 연구에서 제시한 프레임워크는 공공건축물의 자산관리 업무수행에 초점을 맞추어 개발하였으며, 단계별 세부적인 내용을 제시하였다. 이 프레임워크를 실무에 적용한다면 건축물의 가치와 성능을 체계적으로 관리할 수 있으며, 유지관리 예산을 효과적으로 책정할 수 있을 것으로 기대된다.

Most power plants have operated many independent computerize systems for maintenance. Independence of systems have caused complexity of business process and inconvenience of computer system management. Because the equipment and material master data is not standardize and structurize, it is difficult to manage equipment maintenance history and material delivery. Especially equipment classification criterion is important for standardization of every maintenance information. It is necessary to integrate function of independent systems for business process simplification and rapid work flow. this paper provides equipment classification criterion design and system integration method with the case of live system development.

The purpose of this study is to support satisfaction for reasonable management method to elevate the enhancement of management attitude and the satisfaction of management state for Multi-family Housing. This study was intended to find out variables which influence on the satifaction and attitude of resident to the management of Apartment, and to investigate variables influencing on the satisfaction and attitude of resident to the management of Apartment. In this study, survey research method is employed. The sample is taken from 336 APT. resident's living in Seoul, from 13th of Sep. to 20th of Sep, in 1993. Used statistica] method are Frequency, Percentage, 1-test, One-way Anova, Duncan-test, Multip]e Regression. The major finding were as follows: 1) The work of management of Multi-family Housing was classified into three type ; a)administration management b) maintenance management c) community-life control. 2) The management attitude of Apartment inhabitant is very high, especially .the attitude of maintenance management is the higest. But they disagree with the raise of management cost necessary to maintenance management. 3) The satisfaction of administration management, maintenance management, community-life control management is all low in the management condition of Apartment.'1'he management method of present Apartment shows a little problem.

Recently the study related to life cycle cost analysis of railway structure consisted of a complex is proceeded covering several range, which is considering the methodology of efficiency and rationalization for maintenance and analysing long-time behavior of the structure of looking at standpoint from asset management and safety. But LCCA(life cycle cost analysis) of railway structure was almost impossible as there were not anything datum for maintenance plan, such as maintenance periods related to each of components(painting and corrosion of steel, and cracking of elements, etc)and maintenance proportion, despite of its 100-year history. According, for collecting data related to railway truss bridge, bridge record cards and testing safety papers, and researching question, etc are surveyed and classified for LCC Analysis. Especially, LCC assessment on the side of assets-maintenance considering about initial cost, maintenance cost, and indirect cost is constructed. Maintenance period and complementary measure rate are very important in maintenance. To decide maintenance period, Baysian updating method is applied.

As a system complexity increases and technology innovation progresses rapidly, leasing the equipment is considered as an important issue in many engineering areas. In practice, many engineering fields lease the equipment because it is an economical way to lease the equipment rather than to own the equipment. In addition, as the maintenance actions for the equipment are costly and need a specialist, the lessor is responsible for the maintenance actions in most leased contract. Hence, the lessor should establish the optimal maintenance strategy to minimize the maintenance cost. This paper proposes two periodic preventive maintenance policies for the leased equipment. The preventive maintenance action of policy 1 is performed with a periodic interval, in which their intervals are the same until the end of lease period. The other policy is to determine the periodic preventive maintenance interval minimizing total maintenance cost during the lease period. In addition, this paper presents two decision-making models to determine the preventive maintenance strategy for leased equipment based on the lessor's preference between the maintenance cost and the reliability at the end of lease period. The structural properties of the proposed decision-making model are investigated and algorithms to search the optimal maintenance policy that are satisfied by the lessor are provided. A numerical example is provided to illustrate the proposed model. The results show that a maintenance policy minimizing the maintenance cost is selected as a reasonable decision as the lease term becomes shorter. Moreover, the frequent preventive maintenance actions are performed when the minimal repair cost is higher than the preventive maintenance cost, resulting in higher maintenance cost.

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.

The QOS(Quality of Service) recognized by the customer will become the most important thing under the competitive telecommunications market. Korea Telecom is going to develop many system to manage the telecommunication network, to improve the level of QOS, and to increase the revenue. Operation and Maintenance Adiministration System is one of the systems developed to meet those purposes efficiently. This system gathers qualities data from telephone offices or operation centers and analyze the results of QOS improvement activities and evaluate overall QOS. And also system makes it possible to improve the cost/effectiveness of operation and maintenance of telecommunication network. Operation and Maintenance Administration System has four functional modules, i.e., the user interface module, the database management module, the QOS management module, and the database conversion module. The purpose of this study is to develop the QOS management program, one of the four functional modules of the system,using FOCUS 4GL/DBMS. Since Operation and Maintenance Administration System is developed using FOCUS 4GL, every user can handle and maintain the system very easily and reduce system backlogs.

To keep an enterprise's competitiveness on the condition of the automatic manufacturing system such as FA, FMS and CIM, all the maintenance problems should be considered seriously In not only in production and maintenance but also in related industrial safety. As we analyze in the surveys the maintenance management of domestic enterprises and the causes of Industrial accident, there will be necessity of drawing up countermeasures for preventing industrial accidents and for ensuring expertise maintenance technologies. Based on these analyses, the safety information system, maintenance management information system, and the machinery condition diagnosis technique are studied by using of the knowledge-based system under the real-time computer-operating environment and using fuzzy linguistic variable. This computer system based knowledge-based diagnosis can easily provide not only the knowledge of expert system about deterioration phenomenon of industrial robots, but also the knowledge of relating safety and facility all the time. Therefore, it is expected to improve the efficiency of business processes in the production and safety when we use this system.
