컴퓨팅 환경이 유리쿼터스 환경으로 변해가면서 다양한 컨텐츠와 다양한 디바이스들이 등장하게 되었고, 디지털 컨텐츠를 보호하기 위해 DRM(Digital Rights Management) 기술이 적용된 서비스가 제공되고 있다. 그러나 현재 DRM 기술의 디지털 컨텐츠 보안 정책은 일정한 키 길이에 동일한 암호 알고리즘을 사용함으로써 비효율적이고, 사용자의 다양한 요구를 만족시키지 못하고 있다. 본 논문에서는 디지털 컨텐츠에 보안 정책을 효율적으로 적용하고 디바이스의 성능과 디지털 컨텐츠의 가치에 따라 의사 결정 방법인 MAUT(Multi-Attribute Utility Theory) 알고리즘을 이용하여 최적의 보안 등급을 동적으로 결정하는 컨텐츠 암호화 모듈을 설계하고 구현한다.

In this paper, we suggest energy technologies for a plan of future energy technology innovation. In order to evaluate and analyze of the technologies, we consider various methods such as AHP(Analytic Hierarchy Process), CVM (Contingent Valuation Method) and MAUT(Multi-Attribute Utility Theory). According to MAUT, we present between many attributes and priorities of innovation technologies.

This study tried to estimate the environmental value of Youngsan river estuary as there are conflicts on the management policy about Youngsan river estuary. For estimating the detailed functional values of Youngsan river estuary, this study used the contingent valuation method with multi attribute utility theory for. In addition, the survey was separately practiced to on-site and off-site. According to estimating results, the annual value of Youngsan river estuary is about 27.4 billion Korean won. The results of this study are expected to contribute to determine the appropriate level of investment and management policies with regard to the estuary and to provide methodological guidelines for follow-up study.

Weapon system currently considers the research about effect analysis including cost effectiveness methodology for a budget management and an achievement of the military strategy goal. So that, this study considers the theoretical background, strength and weakness of several Multi-Criteria Decision Making, and an effect analysis of weapon system. And AHP(Analytic Hierarchy Process) is selected for the best effect analysis methodology of weapon system. Therefore, we applied AHP to the case study of the new generation Multiple Launcher Rocket System, performing the analysis of cost effectiveness methodology. Using AHP and cost effectiveness methodology, we propose the actual and proper decision making result.

Traffic volume increases due to diversification of industry. Also, Automobile ownerships also increase steadily. It is estimated that the registered number of vehicle is expected to be 20 milion in the year 2015. These trends may result in increasing the number of woman drivers and elderly drivers. Therefore, this study aims to identify routes that reflect characteristics of each driver's preferences. A survey was conducted on different routes attributes for variances drivers. Driver types were classified by gender, age, and driving career. Accordingly, a weight for road composition attribute such as number of lanes, number of accidents, slope was estimated by using Swing Weighting technique in Multi-Attribute Utility Theory. In addition, a case study was conducted and identified weights were applied to routes. In result, drivers commonly prefer short route when they considered their routes. Also, male drivers prefer speedy and shorter route than that of female drivers. Elderly drivers prefer safe routes that represent low accidents rate. Moreover driving career under a year drivers prefer safe and easy routes. Therefore, we may conclude that the necessity of diversified route information is essential in the future car navigation system.

Finding an optimal solution in MADN[(Multi-Attribute Decision-Making) problems is difficult, when the number of alternatives, or that of attributes is relatively large Most of the existing mathematical approaches arrive at a final solution on the basis of many unrealistic assumptions, without reflecting the decision-maker's preference structure exactly. In this paper we suggest a model that helps us find a group consensus without assessing these parameters in specific cardinal values. Therefore, This research provides a comprehensive Decision Making of the theory and methods applicable to the analysis of decisions that involve risk and multiple criteria attributes. after, The emphasis of the procedure will be on developments from the fields of decisions analysis and utility theory of Taguchi Method. This theoretical development will be illustrated through the discussion of several real-world application and a case study. When the multiple number of decision makers are involved in the decision making procedure, the problem of uncertainties invariably occurs, because of the different views between them. In this paper, New decision making model using Taguchi Method is applied to effectively model the multi-attribute-decision making(MADM) procedure in the uncertainties dominated two area(quantitative and qualitative factors), Quantitative factors evaluation is used Loss Function of Taguchi, qualitative factors evaluation is used 50 ratio by each specialist. thus it can be used for aiding of preferable alternative. as a result, We will be proved efficiency about New decision making model of applied Taguchi Method with Analytical presentation of all the expecting outcomes when a specific strategy or an alternative plan is selected under expecting future environment.

전력산업은 환경문제로 인해 사업수행이 점차 어려워지고 있으며, 전원개발계획 수립을 위한 의사결정 단계에서 환경외부성을 고려하는 문제가 중요하게 대두되고 있다. 본 연구는 전력계획수립의 초기단계에서 환경문제를 통합하기 위한 노력의 일환으로, 다속성 효용이론(Multi-Attribute Utility Theory: MAUT)을 적용하여 환경영향의 다속성 지수를 구성하는 접근방법을 제시한다. 먼저 연구배경과 제안된 방법론을 개괄적으로 살펴본 후, 기술적인 판단과 가치 판단에 근거한 지수구성에 요구되는 제반 가정 및 단계를 소개한다. 다음으로, 우리 나라의 전력산업에 대한 실증분석을 통해 다속성 지수를 도출한다. 마지막으로 환경지수와 화폐 간의 트레이드-오프(trade-off) 관계를 분석하여 환경의 사회적 가치(societal value)를 도출하고 연구결과의 유용성에 대해 설명한다.

Time-tradeoff measures and healthy years equivalents were assessed and compared through an empirical study based on Multi-attribute utility theory. The study included 33 student subjects as a pilot study, and 54 end-stage renal disease patients in Wisconsin. The two outcome measures were compared with the survival duration of 1, 5, and 10 years. The results of the study show that the time-tradeoff method and the two-stage method did not lead to the same numerical quantities, although they aim to measure the same quantities (equivalent numbers of healthy years) theoretically. The healthy years equivalents involved more inconsistencies, and were less reliable than the time-tradeoff measures. Overestimation of the healthy years equivalents was observed. This seemed to be caused by the complex procedure of the two-stage method as well as by the preferences assessment biases. Based on the study experiences, the time-tradeoff measure would be recommended for problems involving generic medical applications and health policies.

Bridges are essential and valuable elements in road and rail transportation networks. Bridge remediation is a top priority for asset managers, but identifying the nature of true defect deterioration and associated remediation treatments remains a complex task. Nowadays Decision Support Systems (DSS) are used extensively to assist in decision-making across a wide spectrum of unstructured decision environments. In this paper a requirements-driven framework is used to develop a risk based decision support model which has the ability to quantify the bridge condition and find the best remediation treatments using Multi Attribute Utility Theory (MAUT), with the aim of maintaining a bridge within acceptable limits of safety, serviceability and sustainability.
