A research framework for development of a LCCA based tunnel asset management system

산악지형이 많은 우리나라는 1970년대 이후 급속한 경제발전과 함께 수많은 터널이 건설되어 왔으나 터널의 필요성에 대한 인식에 비해 터널의 유지관리에 대한 관심은 부족한 상태이다. 국내 터널의 유지관리체계는 점검 후 이상이 발견 되었을 때 대처하는 대응적 유지관리 체계로서, 앞으로 노후화 터널이 급격히 증가하면서 각 기관들의 제한된 예산의 범위와 인력으로는 일일이 대응하기 어려워질 것이다. 따라서 본 연구에서는 터널의 유지관리를 전략적이고 장기적인 관점에서의 예방적인 관리 체계로 변환시키기 위한 LCCA(Life Cycle Cost Analysis)기반 터널 자산관리 시스템의 필요성과 개발방향에 대한 프레임웍을 제시하고자 한다. 국외 선진국의 사회기반시설물에 대한 자산관리 수행사례를 살펴보고 국내 터널관리에서의 자산관리기법의 필요성을 분석하였다. 또한, 터널 자산관리에서 경제적, 공학적의 정량적 의사결정 기법인 LCCA 모델을 적용하여 자산관리모델이 개발되기 위한 구체적인 발전방향을 제시하고 이를 시스템화하기 위한 연구개발 프레임웍을 설계하였다. As many parts of Korea are mountainous, many tunnels have been constructed to be in step with rapid economic development since 1970's. However, the interest on maintenance of tunnels is far less than the awareness of need for tunnels. As the tunnel maintenance system is the responsive maintenance system which responds to the problems found during the inspection, it will be very difficult to respond to each problem with the limited budget and manpower of the government agencies when the number of aged tunnels rapidly increase in the future. As such, this study presents the need for the LCCA (Life Cycle Cost Analysis) based tunnel asset management system to transform the tunnel maintenance to a preventive management system in a strategic and long-term viewpoint and proposes the framework for development direction. It observed the asset management implementation cases of social infrastructure in other countries and analyzed the need for asset management technique to manage the tunnels in Korea. Moreover, it applied the LCCA model, which is the economic and engineering quantitative decision making technique, for tunnel asset management to present the concrete direction for development of an asset management model and designed the R&D framework to systemize it.

Harnessing the value of data in asset management for production assurance and to lower operating costs

With rising costs, a tight labour market, and prolonged global economic uncertainty, it is unsurprising that investment decisions are being re-evaluated across Australia's resources and energy industry. Amid this tough market environment, effective asset management has never been more important. Asset management was first adopted by Australia's oil and gas industry in the early 90s and is now well entrenched. There is widespread acknowledgement that it breaks down project complexity and plays a critical role in maximising project net present value. If done well, asset management takes a long-term view of asset life-cycles–from concept and creation, to services that deliver production assurance and lower costs. While these principles are well understood across the market, asset data capture and analysis–a critical element to successful asset management–requires ongoing review. Accurate and comprehensive asset data is the basis on which all good asset-management decisions are made. Developments in geographic information systems, SAP, and cloud-based technology are redefining the way asset data is collected, stored, analysed, and fed back into asset-management decisions. Asset managers of oil and gas assets should, therefore, be asking themselves three important questions: Are we using the latest technology to collect, store, and analyse asset data? Which project stakeholders need to interact with the data? Do our existing or planned asset-management models have the capacity to integrate and evolve with new technology as it develops?

교량의 유지관리를 위한 BIM기반 자산관리 모델 개발에 관한 연구

The most of domestic bridge has an used life under 30 years, Future maintenance budgets can be expected to increase. However, because of bridge maintenance budgets are limited, demand for asset management being performed to achieve required performance within available budget is increasing. To perform effective asset management of bridges should be made the best use of information to occur in all phase of construction project. Therefore, the development of system and DB is required to support asset management by effective information management. The objective of this study is the development of the BIM-based bridge asset management model. Through previous research survey, BIM capabilities and asset management components were established and mutual linkages were examined. Bridge asset management model was composed of alternate assessment model. In addition, BIM-based asset management model was performed case studies to verify feasibility and applicability. The proposed model can be applied to a current bridge maintenance procedures and supported to perform effective bridge maintenance tasks within a limited budget.

Estimation of Discount Rates for Assessing the Efficiency of Investment Projects in the Framework of Optimal Financial Asset Management

Singled out for this study is a model of optimal asset management for a firm in a deterministic situation (i.e., given full information) that would allow to refine and modify a traditional definitions of discount rate as the highest rate of return on alternative investment opportunities. It is shown that, in general, the discount rate (determined as the rate of decline in the shadow price value of money in the optimal plan) is time-variable and depends not only on the general situation in the market, but also on the financial position of the planning firm. The constructed model provides opportunities for formulating the precise conditions for the financial feasibility of a project and justifying the structure of its efficiency criterion. It appears that the criterion of efficiency in question differs from the net present value (NPV) -- in addition to the discounted sum of cash flows from the project, it must take into account the market value of fixed assets created under the project. We also consider the accounting issues of inflation, uncertainty and risk in evaluating the effectiveness of the project and setting the discount rate.

Definition of generic re-use operating models for electrical and electronic equipment

This paper aims to define a typology for the most common re-use operating models for electrical and electronic equipment (EEE). The scope of the study is Information and Communication Technologies (ICT) and Large Household Appliances (LHA). To describe and categorize re-use operating models, an analytical framework was defined, which consists of the four dimensions supply chain, offer, customers and financial structure. Based on this framework, standardized telephonic and personal interviews were conducted with 28 case study partners.Four re-use operating models for ICT and LHA were identified:•The Networking Equipment Recovery Model•The IT Asset Management Model•The Close the Digital Divide Model•The Social Enterprise ModelThe first two models are for-profit, whereas the last two are not-for-profit. Moreover, models differ in terms of customer segments and products and services offered to these customers. The Networking Equipment Model processes Information Technology Networking Equipment for original equipment manufacturers (OEMs) as main customers. IT Asset Management organizations specialize in refurbishment of desktop and notebook computers for resale to distributors and retailers. The Close the Digital Divide Model provides used computers to eligible recipients in developing countries. Social Enterprises prepare computers and peripherals or large household appliances for re-use and sell them through retail shops to individual users.The identified models constitute generic ways to structure re-use operations along the four dimensions of the analytical framework (“supply chain”, “offer”, “customers”, “finance”). Different entities can utilize one or multiple combinations of these models.

Analysis of Wastewater and Water System Renewal Decision-Making Tools and Approaches

AbstractIn regards to the development of software for decision support for pipeline renewal, most of the attention to date has been paid to the development of asset management models, which help an owner decide on which portions of a system to prioritize for needed actions. There has not been much work in terms of providing guidance on whether to rehabilitate or replace the pipeline asset and choosing the most appropriate methods for that work. These decisions involve the evaluation of many criteria, which must be considered thoroughly to determine the optimal way of rehabilitating or replacing these systems efficiently and cost effectively. As part of the U.S. EPA Aging Water Infrastructure (AWI) Research Program, one key area of research, conducted in collaboration with wastewater and water utilities, was a study of the current approaches available for making rehabilitation versus replacement decisions. The purpose of this study was to (1) identify the current methodologies and decision support systems ...

Integrating Transportation and Economic Models to Assess Impact of Infrastructure Investment

This study explores how different asset management, traffic forecasting, performance, and economic models can be integrated to show the national economic implications of transportation funding and performance gaps under different scenarios. Asset management models have often been utilized to assess and forecast the condition and performance of current infrastructure. Travel demand models have been used to anticipate how traffic volumes are likely to develop over time depending on capacity improvements. User-cost models have been used for cost–benefit analysis and the management of trade-offs, and economic impact models have been used to characterize transportation choices in terms of earnings, output, and employment. This study explores how a sequence of these models when applied to a consistent data set with consistent assumptions can address the overall relationship between physical transportation system conditions and performance, traffic patterns, transportation costs, and economic impacts. The results point to a vertically integrated and economically defensible approach to needs-based planning with an understanding of the national economic significance of transportation investment choices.

General asset management model in the context of an electric utility: Application to power transformers

GAMMEU 1 1 GAMMEU: general asset management model for an electric utility. constitutes an integrated approach that covers the different elements related to the asset management of power transformers in the environment of a utility. GAMMEU harmonizes and inter-relates all the relevant subsystems of the asset management that normally are studied as individual entities and not as a system. Concretely, GAMMEU consists of a platform for data integration, an intelligent system for detection and diagnosis of failures, a failure rate estimation model, a module of reliability analysis and an optimisation model for maintenance scheduling. In this work, a brief description of the elements of GAMMEU is presented and the implementation of the intelligent system for detection and diagnosis as well as the failure rate estimation model is exemplified using data of measurements performed in real power transformers. A robust anomaly detection module using prediction models based on artificial intelligence techniques was developed for top oil temperature monitoring and the use of decision trees as classifiers for the assessment of FRA 2 2 Frequency response analysis. measurements is also illustrated. For failure rate estimation, the use of a model based on hidden Markov chains is presented using data of dissolved gas analysis tests. The experience obtained from the implementation of part of the modules of GAMMEU using real data has demonstrated its feasibility.

Asset management of social landlords based on value creation at neighbourhood level

PurposeThis paper aims to explore an approach in which asset management strategies of housing associations are largely determined at neighbourhood level and in which the development of the market value is one of the key criteria.Design/methodology/approachThe paper discusses the characteristics of the existing asset management models and their drawbacks. It describes area‐based policies, and it argues how the neighbourhood level can be incorporated in asset management and why this also helps to solve some of the drawbacks of the portfolio‐based models derived from strategic business planning. This approach is illustrated with the practice of housing association Stadgenoot.FindingsIt is argued that asset management based on value creation at neighbourhood level has significant advantages above the “traditional” business planning approach and suggests some further directions for elaboration of this approach.Practical implicationsThis approach enables housing associations to improve their asset management strategies.Originality/valueThe paper presents a new view on asset management in response to traditional, top‐down, rational planning models.

Novel Approach in Pipe Condition Scoring

A major challenge in sewer and water pipe infrastructure management is determining structural condition scores for pipe assets. The methodology used to determine the condition of pipes should be relevant, repeatable, and validated. Additionally, to be appropriate for use in risk-analysis models, the scale selected to represent the structural condition should be linear. The methodology developed in this paper enables previously developed pipe statistical failure models to be translated into a mean time to failure (MTF) for individual pipes. By using the economic concept of discounting, the MTF is then used to score the structural condition of the pipe, providing an appropriate structural condition score for use in risk-based asset management models. This methodology for determining the structural condition score has several advantages over previously developed models: the results can be easily interpreted and validated, and the resulting scale is linear. Additionally, the system can be implemented for pipes with differing levels of available data, such as for pipes with and without inspection results.

ASSET MANAGEMENT IN HISTORIC BUILDINGS CONSERVATION: CASE OFBRAGA AREABANDUNG

This paper tries to explore the initial possibility of asset management in managing assets governed by the local government. In this research, historic building assets conservation is treated as a model in implementing asset management. Asset management model is implemented in many places in managing infrastructure network, but has never been implemented in historic building management in Indonesia. Quite different than any other modeling in general, the case for historic building should iteratively relate to the characteristics and issues of historic buildings and any management opportunities that can be done by the government as the responsible party in managing historic buildings. Asset management implementation in this research initiated with identifications of related attributes of the historic building assets based on available and applicable management possibilities. This paper shall not explore the detail exposition of each attributes found, but the approach that is implemented through asset management which shows comprehensive understanding on this issue of historic building management. The effort of understanding the issues and types of management that is possible in historic building that then may give rise to the identification attributes of this issue that shall be the start of asset management implementation for historical buildings based on information system. It is also understood that this study may be further developed especially in drilling down the attributes used prior to asset management model implementation.

Alternative decision models for liability-driven investment

Traditional Asset and Liability Management (ALM) models have been recently recast as Liability-Driven Investment (LDI) models for making integrated finan-cial decisions in pension schemes investment: matching and outperforming liabilities. LDI has become extremely popular as the decision tool of choice for pension funds. The last decade experienced a fall in the equity markets, while bond yields reached low levels. The UK Accounting standard FRS17 (since 2001, replacing SSAP24) requires the assets to be measured by their market value and liabilities to be measured by a projected unit method and a discount rate reflecting the market yields then available on AA rated corporate bonds of appropriate currency and term. When these new regulations were introduced, liabilities became harder to meet. In the case of a deficit, the pension fund trustees and employers have to agree on extra contributions to fill the deficit within 10 years time. Furthermore, deficit or surplus has to be fully included on the balance sheet of the sponsoring company. In the Netherlands and the Nordic countries, LDI models have become established (see C. Dert, 1995 and Drijver, 2005); the United Kingdom, Italy and a few other European countries are close followers of this trend. Traditionally, assets and liabilities were con-sidered separate. In asset management, the aim was to maximize return for a given risk level. However, the matching of the liabilities was not taken into consideration. The main argument was that assets should be made to grow faster than liabilities. The modern integrated approach to LDI considers the cash flow streams for invested assets of fixed-income portfolios enhanced by interest rate swaps and in some cases of swaptions.

Managing Assets in the Infrastructure Sector

In view of the importance of managing assets and the lack of research in managing assets in the infrastructure sector, we develop an asset management model in this study. This model is developed in line with the unique characteristics of the infrastructure assets and asset management principles and criteria. In the proposed model, we consider activities at three levels, namely the strategical, tactical and operational levels. The interviews with experts in asset management and officials in several Dutch organizations have proven the potential of our asset management model.
