산업이 발전함에 따라 도로 터널의 사이즈와 길이는 계속적으로 증가해 왔으며 그에 따른 터널에서의 리스크 또한 증가되었다. 도로터널에서 환기방식을 결정할 때는 다양하고 많은 고려사항을 염두에 두어야 한다. 현재로서는 이러한 것들을 체계적으로 고려하여 의사결정을 지원할 수 있는 방법론 내지 시스템이 제대로 구축되어 있지 않은 실정이며 대부분 전문가의 경험을 바탕으로 한 주관적 판단에 의존하고 있다. 본 연구에서는 기존의 경제성 내지 주관적 판단에 국한하여 의사결정이 이루어지던 관행에서 벗어나 안전성, 환경친화성 등도 충분히 고려하여 결정을 내릴 수 있도록 터널별 최적의 환기방식을 선정하기 위한 일련의 절차와 기준을 제시하였다. 이 때 다속성 효용이론과, AHP기법을 적절히 활용하여 전문가 및 설계자의 주관적/정성적 평가를 객관적/정량적으로 측정할 수 있도록 하였으며, 환기 방식별 종합적 효용을 산출할 수 있는 함수를 도출하기까지의 방법론을 제시하였다. 본 논문에서 제시하는 방법론을 바탕으로 보다 합리적인 의사결정이 이루어질 것을 기대한다.

기업의 신용을 평가하는데 있어 정확한 파산확률의 추정은 무엇보다도 중요한 요소이다. 선형로지스틱회귀모형보다 성능이 좋은 기대효용최대화 (Maximum Expected Utility) 모형이 제안되었다. 그러나 이 모형에 포함되어 있는 모수의 일부가 북미와 유럽지역의 자료를 토대로 경험적으로 추정되어진 것이므로 우리나라 기업에 바로 적용하기에는 무리가 있다. 따라서 우리나라 중소기업의 자료를 바탕으로 모수를 재추정하여 한국형 MEU모형을 제안하고자 한다. 34,057개의 중소기업을 이용하여 한국형 MEU모형을 설계한 결과, 기존의 북미 유럽형 모형과 차이가 많이 나는 것으로 나타났으며 성능면에서도 선형로지스틱회귀모형보다 전 산업분류에 걸쳐 한국형 MEU모형이 매우 우수한 것으로 나타났다.

From 2000, the world plant market, especially plant developing business related to oil and gas, has been increasing. Domestic construction companies advance to overseas plant construction market actively, and proportioning to this, an importance of utility construction is increasing. However, the project becomes large and high-tech, and many companies experience difficulty of project management due to relatively high risk of overseas construction. In this study, we built the standard process with which domestic company can evaluate the risk of overseas plant utility construction. Primary factors for risk evaluation is derived, classification system is made out, primary factor is analyzed, and counter plan is suggested. And thorough management of risk is performed by risk management organization that manages the risks, risk control methods, reports and monitors through risk sheet and risk action log from the start of project to the end.

Renewable energy is not a new terminology. One of the fastest growing renewable energies is solar energy. The implementation of solar energy provides several advantages including the reduction of some of the environmental risks of fossil fuel consumption. This research elaborated the importance of the adaption of solar energy by developing a spatial decision support system (SDSS), while the Residential Solar Energy Adoption (RSEA) is an instantiation artifact in the form of an SDSS. As a GIS web-based application, RSEA allows stakeholders (e.g., utility companies, policymakers, service providers homeowners, and researchers) to navigate through locations on a map interactively. The maps highlight locations with high and low solar energy adoption potential that enables decision-makers (e.g., policymakers, solar firms, utility companies, and nonprofit organizations) to make decisions. A combined qualitative and quantitative methodological approach was used to evaluate the application's usability and user experience, and results affirmed the ability of the factors of utility, usefulness, and a positive user experience of the residential solar energy adoption of spatial decision support system (RSEA-SDSS). RSEA-SDSS in improving the decision-making process for potential various stakeholders, in utility, solar installations, policy making, and non-profit renewable energy domains.

Objectives: This article examines the diversity of healthy cities evaluation in practice and discusses the major conflicting issues in evaluating healthy cities to offer implications to academics and cities for application in their field. Methods: The author discusses issues on major topics that arose from a review of literature on selected articles from peer-reviewed journals, books and gray literature. The recently developed Korean Healthy Cities evaluation framework is used as a main source of reference. Results: Evaluating healthy cities is in itself a political process and requires multiple methodologies and diverse sources of data. Details of the evaluation process depend on the purposes and goals predetermined by the stakeholders. The Korean Healthy Cities evaluation framework applies these principles and suggests a participatory approach to evaluation, selection of indicators that provide evidence on the process of change and to use mixed evaluation methods. The involvement of stakeholders in the evaluation process can also be a useful tool to further strengthen partnerships and strategies for healthy cities. Conclusion: Cities need to engage more in evaluation activities and develop necessary skills and capacity to produce utility-driven evidence.

Every public agency governing infrastructure has to plan effectively for rehabilitation of existing facilities within the constraints of the capital program. Numerous technical, social, political, financial, and management constraints govern the decision to rehabilitate a facility. However, without a systematic procedure for selecting facilities for rehabilitation, within the prevailing constraints, it is possible that the funds available for rehabilitation might be suboptimized. Therefore, a decision support system that assists the user in selecting facilities for rehabilitation while considering the technical, social, financial, and political and management constraints will be useful in the decision-making process. This paper compares the Analytical Hierarchy Process (AHP) with the Swing Weight method used to prioritize functional criteria for suburban station rehabilitation. This paper also contains a brief discussion about the relevance of the Multi Attribute utility theory in developing a decision model for the problem at hand. The results of this paper provides the user with a decision support system that would prioritize the stations in order of their weights obtained by a systematic evaluation of various criteria and sub-criteria involved in the decision making process

This study examined the factors which have influence on the welfare facilities for the elderly and analyzes their efficiency. It investigated theoretical studies and preceding studies and divided the efficiency evaluation factors into input and output factors. Input factors included budget, the number of workers and clients and facility area and output factors were operation management, the number of clients, profitability and welfare for the elderly. To sum up the analysis results of evaluation factors of welfare facilities for the elderly, the analysis of relative importance of input showed that budget was most important. As a result of analyzing the relative importance among detailed items, balance sheet and professional manpower were highest. Input factors by facility types showed that the budget for utility facilities and living facilities were highest. In output factors, utility facilities and living facilities were highest in management systematization and welfare for the elderly, respectively. In efficiency evaluation, utility facilities for the elderly showed 100% of efficiency in CCR and BCC models. In welfare facilities for the elderly, while CCR model showed 100% of efficiency in facility types A, C, D, and F, the efficiency was low in facility B (79.89%), E (77.14%), and G (80.72%). In BCC model, facility E was low as 78.69%. In efficiency comparison between utility facilities and living facilities for the elderly welfare, the efficiency of utility facilities for the elderly welfare was higher. Therefore, this study investigated the efficiency of welfare facilities for the elderly as its main purpose and presented policy suggestions based on the research results as the alternative.
