  • Pedestrians have been exposed to dangerous traffic environments, in which walking spaces in a city decrease without improved facilities even though cars increase. Such poor walking environments are deadly dangerous to the vulnerable as well as the non-vulnerable. This study analyzed the road facilities use characteristics according to a type of vulnerability in order to improve traffic safety and walking environment for vulnerable pedestrians. This study surveyed the vulnerable in terms of issues that they encountered on existing walkways and conducted the analytic hierarchy process (AHP), which took all quantitative and qualitative variables into account. The results of Level-3 analysis were showed that the elderly and the disabled were partially similar; both felt most inconvenient at enter-exit sections, steep walkway and bad paved walkway. Unlike those results, people with children and/or infants answered that overpass or underpass walkways without lifting facilities were most inconvenient walking environments.

  • Intrusion tolerant system enables essential services to maintain for a period of time under system failure, malicious attacks and is gaining more importance in national defense, communication infrastructure, and financial sector. However, few objective evaluation criteria for companies and agencies to introduce an appropriate system are available. This paper proposes a suitability evaluation method, using Analytic hierarchy process and fuzzy integral, for intrusion tolerant system, along with evaluation criteria which considers the characteristics and costs of systems in addition to other factors.

  • The competition between ship management companies is fierce as a result of global trend towards increased specialization. In order for ship management companies to remain competitive, it is necessary to understand the local and global factors and the changing circumstances that impact shipping markets and trade patterns. To better understand these factors, a study and analysis of drawing priority of the competitiveness-evaluation factors of ship management companies was conducted using Analytical Hierarchy Process(AHP) as a method dealing with dicision-making problem. As a consequence of this analysis, it was determined that human resources, both shipboard and land management, were a primary factor in ship management company's competitiveness. Thus, the acquisition and retention of capable staff was a key aspect of assuring a ship management company's competitiveness.

  • The purpose of this research is to derive and evaluate priorities for critical factors that must be determined before an enterprise adopts a cloud computing service. AHP analysis techniques were used to reflect decisions made by experts as research methods. AHP is a decision-making technique that expresses complex decision-making problems hierarchically and derives the best alternatives through pairwise comparison between the items of the hierarchy. Compared to the existing statistical decision making techniques, the decision making process is systematic and simple, making it easy to understand. In addition, the procedure is also reasonable by providing an indicator to determine the consistency of the decision maker in the analysis process. The analysis results of this research showed that security was the first priority, reliability was the second priority, and economic efficiency was the third priority. Among the factors in the first-priority security items, the access control rights and the safety factors of external threats are the most important factors. Research results can be used as a guideline in future practice, and it is necessary to evaluate, compare and analyze the satisfaction of companies that have adopted cloud computing services in the future.

  • 본 연구는 지역이 가지고 있는 중요한 자원을 자연 생태적 요소, 역사 문화적 요소, 시각 환경적 요소 등으로 분류한 후 충남지역 16개 시 군을 대상으로 군의 상징적 요소로서 가치 있는 자원의 발굴과 동시에 개발에 밀려 점점 사라져가는 농산어촌 대표경관의 추출을 통해 자원의 중요성을 AHP(계층 분석적 의사 결정기법)모델을 통해 분석하여 상호 중요도를 파악하고자 한다. 이러한 연구를 통해 지역의 대표적인 상징적 요소와 경관적 요소의 상관성을 파악함과 동시에 중요도에 따라 순위(ranking ordering)를 결정함으로서 지역의 정체성(identity)을 확보하고, 향후 보전할 자원의 특성을 파악함으로써 지역의 문화적, 환경적, 생태적 자원가치의 패러다임을 구축하고자 한다. 연구방법은 1차적으로 문헌조사를 통한 지역의 자원특성에 대한 분류체계를 설정한 후 전문가 집단을 선정하여 설문조사를 통한 통계적 분석방법을 사용하고자 한다. 전문가 집단은 지역에 대한 비교적 잘 파악하고 있는 지역전문가(관련대학 교수, 공무원, 연구원 등)로 구성하였으며, 1, 2차 설문을 통한 상징성 및 대표경관자원을 최종적으로 선정한 후, 3차 설문에서는 농촌 및 경관관련 전문가 집단을 재선정하여 AHP(계층 분석적 의사결정)기법을 통한 자원의 중요도를 파악하고자 한다. 분석방법은 자료의 계량적 분석을 위해 통계프로그램인 SPSS 12.0 for Windows와 도출된 상징요소의 가중치를 파악하기 위해 AHP 프로그램인 ExpertChoice 2006을 사용하여 도출된 상징요소의 가중치별 순위를 측정하여 분석의 과학성, 논리성, 타당성을 확보하고자 한다.

  • 최근 기업 정보에 대한 온톨로지 구축 필요성이 대두되면서 기업의 투자 비용과 시간을 고려한 온톨로지 구축 대상 선정을 위한 효율적인 기법이 요구되고 있다. 그러나 기존의 온톨로지 구축 방법론에서 제시한 대상선정 기법은 전체를 대상으로 하거나, 특정 영역만을 대상으로 한다는 한계가 있다. 본 논문에서는 정성적요소를 포함하는 다기준 의사결정에서 정량적인 평가를 지원하는 의사결정지원기법인 AHP(Analytic Hierarchy Process:계층화분석법)기법을 온톨로지 구축 대상 선정에 적용하는 방법을 제안한다. 이러한 방법을 통해 온톨로지 적용대상의 우선순위를 결정지을 수 있으며, 기업의 온톨로지 구축시 목표와 전략에 맞는 대상선정의 정량적 기준을 제공할 수 있다.

  • It's hard to express a lot of information within the drawings and the specifications as construction projects have gradually become large-size and complex. So, disputes are caused by that and reason that the usual practice(culture) of contract of the constructions in Korea is based on unfair rather than the fair principle between clients and contractors. However, the contractors don't try to solve this kind of things because they are worried about at their disadvantage situation. Therefore, this paper deduced the factors in the pre-dispute phase by analysing the cases of the civic counseling in the office of supply and the pre-dispute factors, and conduct analysis on the factors' importance by using AHP. The results will be used for a check-list to prevent the disputes.

  • Emerging three-dimensional television (3DTV) as a new IT product shows a possibility that television is not for just watching broadcasting, but an attractive tool for applying it to our real life. Three dimensional television is generally more effective and attractive than two-dimensional television (2DTV). But it still needs continuous technological improvement to solve its inherent limitations until many customers decide to purchase 3DTVs without hesitation. Innovative products like 3DTV encounter a quality problem leading purchase decision by customers. Quality is regarded as one of the most important factors affecting customers to adopt and use the product. Furthermore, measuring quality effectively is considerable for the 3DTV research. In this paper, we suggest the Analytic Hierarchy Process(AHP) method for evaluating 3DTVs in a view of quality. We describe quality criteria affecting the 3DTV selection through a literature survey and develope an analytical method for measuring quality. We classify the quality of 3DTV into four types and suggest a concept of the quality ratio as a measurement criteria instead of the quality gap. Though a numerical example, we show how priorities of 3DTV with versatile manufacturers is computed.

  • 요구공학의 궁극적인 목표는 이해당사들의 요구사항을 수용하고, 이를 적절히 설계 및 반영하여 프로젝트를 성공하는데 있어 그 목표를 두고 있다. 그러나 일반적으로 수렴된 요구사항들은 상호간에 충돌이 발생하거나, 합리적인 대안을 이끄는데 있어 많은 문제점을 드러낸다. 따라서, 이를 극복하기 위해 다양한 대안들이 제시되고 있다. 본 논문에서는 이해당사자 상호간의 영향력을 분석(정준상관분석)하여, 중요도 평가를 위한 척도를 만들고, 이를 계층분석적 의사결정방법의 초기 단계에 적용하여 우선순위에 의거하여, 최종 대안을 선택하게 될 것이다. 이를 마지막으로는 위의 과정을 WinWin 협의 모델에 적용하고자 한다.

  • This paper performed studies on a guide for an environmental assessment necessary to select railroad route optimally, and presented techniques for an environmental friendly route selection using AHP(Analytical Hierarchy Process) as an objective method. The AHP is an approach to decision making that involves multiple choice criteria into a hierarchy and assessing the relative importance of each criterion, and determining an overall ranking of the alternatives. For the purpose of this study, we established the weight and the order of major environmental assessment items based on the survey of experts. The results of the weight by AHP were in order of Fauna & Flora, Topography & Geology, Nature Environmental Assets, Noise & Vibration, Water Quality, Landscape and Air Quality indicating natural environment should be in priority. To develop the more efficient environmental friendly route selection systems, it is necessary to consider economical, technical, and social aspects in addition to environmental consideration.
