Bridges, which constitute one of the key facilities in a social infrastructure, are easily accessed and used by users, so that keeping their performance above a certain level is essential. According to various cases in the U.S., Japan and Europe with a long construction history, it is expected that the maintenance cost of bridges in Korea will increase continuously in the future, so a rational decision making system based on engineering factors is necessary to optimize the performance of and maintain them by allocating the limited budget efficiently. This study is a preliminary basic study for the purpose of developing a common asset management system for managing all of the bridges and maintaining the level of service provided by them. The scope of this preliminary study is limited to bridges in urban areas. The bridge asset management system for bridges in urban areas, their level of service (LOS) and performance measure (PM) were developed by carrying out a workshop consisting of both experts and stakeholders. The analysis on the weights of the value and performance measure for each performance indicator was carried out by using the multi-attribute utility theory and the AHP method. In order to confirm the application of the weight of the performance measure and value of the performance indicator, six bridges in an example city were selected, LOS analysis was applied and its results were reviewed.

Recently, the maintenance concept of infrastructure has been changed from the stability management of the structure determined by the safety inspection of the existing facilities to the asset management related to evaluating and managing the performance of the facilities. For management of the property of the facilities, it is necessary to efficiently classify their information for the maintenance and service level of the facilities and to manage them. In the case of power plant facility, especially, it is a complex structure, which is constructed in a various component and detail. In this study, therefore, the components of power plant facility were classified into facilities, spaces, parts, and elements considering the type of integrated construction classification system in Korea. To reflect the deterioration rate of the facility in accordance with environmental conditions such as airborne salt and humidity etc., it was classified by adding direction, interior, and exterior condition of each component not to be considered in the existing classification system for its effective and systematic maintenance, since it is generally located in the coastal area due to the operation of the power generation structure. The classification system developed in this study can be used as fundamental data for development of the computer system for asset management of power plant facility.

In Korea, much effort is being made to introduce asset management for improved efficiency and lower costs. Many researches related to asset management are ongoing, but asset management for public facilities is still in its early development stage in many countries including Korea. It is necessary to continuously improve and complement asset management for its successful execution. Thus, there should be a series of performance measurements and evaluations to perceive the current state of asset management in Korea from which to set future goals. In developed countries including Australia, asset management performance is measured using various methods for diverse purposes. The Korea Institute of Construction Technology has recently launched a study entitled Development of an Asset Management System for Public Facilities (KTAM-40) to change the country’s existing countermeasure-type maintenance system into a preliminary maintenance system and to suggest asset management evaluation parameters. this study aims to develop performance indicators of effective asset management with respect to its utility, which shall include all matters that are important for the efficient measurement of the management of domestic public facilities using the BSC (Balanced Score Card) method, and AHP method.

국도는 사회간접자본 중 하나로서 지속적으로 관리되어야 그 기능을 발휘할 수 있는 국가의 중요한 자산이다. 지금까지는 국도를 포장관리시스템이라는 체계로 관리하여왔다. 이 포장관리시스템은 시설물유지관리차원에서 사회기반시설을 관리하는 것으로서 주로 관리자 관점에서 공학적 판단을 기준으로 최소의 비용으로 공용수명을 최대화하는 모델이다. 그러나 경제발전으로 국민의 소득수준이 올라감에 따라 기본적인 욕구가 해결되어 이제는 납세자로서 국민의 동의는 국가의 정책을 결정하는데 중요한 변수로 작용하기 시작했다. 따라서 사용자 관점의 평가는 이러한 요구의 수준을 측정할 수 있는 중요한 척도가 되었으며 이에 기반한 LoS(Level of Service, 서비스 수준)라는 지수를 시설물 자산관리에 활용하려는 여러 가지 시도가 있다. 이 논문에서는 기존 국도포장관리시스템의 정보모델과 KTAM-40(Korea Total Asset Management-40)이라는 자산관리 정보모델을 비교하여 LoS의 필요성과 도로포장자산관리에서 LoS가 사용자 관점을 반영하는 방식을 조명해 이의 장점을 밝히고자 한다.

소프트웨어 자산을 효과적으로 유지보수하기 위하여 자산의 어느 부분을 수정할 때 변경에 의해 영향을 받는 부분을 예측하여 필요한 경우 함께 수정하도록 하는 방법이 필요하다. 이러한 변경 영향 분석 방법을 사용하면 개발자는 소프트웨어 자산을 수정할 때 함께 수정해야 할 부분을 수동으로 찾는 노력을 줄일 수 있고, 함께 수정이 필요한 부분을 빠뜨리지 않을 수 있어서 자산 변경 시 발생할 수 있는 오류를 방지할 수 있다. 변경 영향 분석 방법을 기업의 소프트웨어 개발에 실제적으로 적용하기 위해서는 방법을 지원하는 도구가 필수적이다. 하지만 기존 상용도구들을 현업에서 사용할 때 한계가 있어 개발자의 요구사항을 반영한 새로운 변경 영향 분석 도구의 개발이 필요하였다. 본 논문에서는 이러한 도구의 요구사항을 설명하고, 이를 반영하여 개발한 새로운 지원도구를 제안한다. 제안하는 도구는 플래시 메모리 소프트웨어 도메인에 적용되어 검증되었다.

Management of social infrastructure has been advanced from facility management (FM) to asset management (AM), which adopts the aggressive and proactive methods in predicting the deterioration of infrastructure, prevents failures, and eventually saves maintenance cost. Infrastructure asset management is not a simple engineering technique, but it is a new paradigm evolved from facility management practices. To implement the infrastructure asset management successfully, organizational reform is very important. This paper suggests critical success factors and key performance indicators to implement the infrastructure asset management for facility managers of government owned social infrastructures such as roads and bridges. Reorganizing the facility management group requires new vision, objectives, strategies for the paradigm-changing asset management. This paper uses Balanced Score Card (BSC) which is a proven method in measuring and setting new objectives for an organization. Once the performance indicators are reviewed repeatedly by facility managers through experts workshops, developed BSC can be used in practice. This paper discusses the development of robust BSC scoring method through in depth literature reviews and investigation of asset management practices of domestic and international cases.

This paper examines the operating performance of firms that for a four-year period, held more than 15% of their assets in cash and cash equivalents. During next four years, operating performance of firms maintaining high cash persistently is greater than the performance of firms matched by size and industry or firms adopting transitory high cash policy. Furthermore, the effect of persistent cash holdings on operating performance depends on the ownership structure and the level of information asymmetry. Foreign investors deteriorate the operating performance of high cash firms, suggesting that potential M&A and the pressure of excessive dividend reduce the usefulness of cash. The level of information asymmetry enhances the operating performance for the firms adopting persistent high cash policy. It suggests that cash holdings reduce the costly external financing and underinvestment problem for firms with high information asymmetry.

National highway is one of the social infrastructures that continue to be managed in order to serve their full functions. The national highway has been managed by the Pavement Management System (PMS) until now. The PMS manages the highway as a way of facility maintenance and maximizes the service life of the highway with minimum cost. The cost is evaluated mainly with a facility manager's perspective based on engineering judgment. People's needs of quality of life have been increased as their income level is rising and naturally the opinion of citizen as a taxpayer plays an important role in determining national policy. Therefore, the contentment of a user's perspective was the starting point of addressing these needs. The Level of Service began to be used as a measure for the evaluation of the user's perspective. In this thesis we would like to design an application and a data architecture for a pavement asset management system and to show how it meets the requirements of KTAM-40 Systems.

We are developing asset management information systems to introduce the preventive/proactive approach at operation and management (O&M) of infrastructures. The objective of this study is to explore the future direction for development and operation of asset management information systems. So, we developed the success model and selected the evaluation criteria for analyzing user satisfaction to assess the expected performance of asset management information systems and the degree of impact on asset management functions to operation and management of highway transportation facilities. We estimated the relative importance weight according to the selected evaluation criteria through AHP analysis. We verified the logical consistency of the importance weight and exclude biased outlier from importance weight group using the concept of the Compatibility.
