  • 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.

  • According to high-rise, complexation, and enlargement of buildings, various construction methods are being developed, and the significance of construction method selection about main work types has emerged as a major interest. However, it has been pointed out that hand-on workers cannot consider project characteristics carefully, and they lack an objective standard or reference for main construction method selection. Hence, the selection is being made depending on hand-on workers' experience and intuition. To solve this problem, various studies have proceeded for construction method selection of main work types using Artificial Intelligence like Fuzzy, AHP and Case-based reasoning. It is difficult to apply many different kinds of construction method selection to every main work type with consideration for characteristics of work types and condition of a construction site when selecting construction method in the field. Accordingly, this study proposed the decision-making model which can apply to fields easily. Using matrix analysis and liner transformation, this study verified consistency of study models applied in the process of soil retaining selection with a case study.

  • 개발로 인한 환경변화는 관련 분석모형을 통해 직접적으로 예측하기 하는 것이 가장 바람직하지만 데이터 취득의 어려움, 분석 방법론의 부재 등의 이유로 정량적 평가가 어려운 현실이다. 그렇기 때문에 수자원사업을 계획시 대부분 환경적인 영향을 매우 정성적인 형태로 평가하거나 수질과 같은 대표적인 항목에 대해서만 예측하는 수준이다. 기존의 연구 또한, 유역 또는 행정구역의 현재의 현 상황을 평가하기 위한 것이 주이며, 수자원사업과 관련성이 적은 항목도 일부 포함되어 있기 때문에 수자원사업의 특수성을 반영하기에 한계가 있다. 현 상황의 이러한 문제점을 인식하여 본 연구는 오늘날 대표적 의사결정 기법이라 할 수 있는 계층화분석과정(AHP)과 다속성효용이론(MAUT)을 활용하여 향후 수자원사업과 관련된 다기준의 사결정 과정에서의 환경성 평가방안을 제시하였다. 환경성 평가기준은 수질, 경관, 생태계 이렇게 세 가지 항목으로 구성하였고, 각 평가기준에 대한 수준을 직접적으로 대변 가능한 정량화 방안을 제시하였다. 그리고 앞서 정량화된 값을 표준화하기 위하여 MAUT 기법으로부터 평가기준별 효용함수를 도출하였다. 한편, 사업을 시행함에 따라 예상되는 환경성변화는 사업전 환경성과 사업 후 환경성을 비교하도록 하였고, 이때 해당사업의 특수성을 반영하고자 별도의 설문과정을 통해 평가기준별 가중치를 결정하였다. 본 연구는 환경성 검토시 생태학적, 물리적 분석에 기반을 둔 정량적 예측의 어려움을 보완하기 위해 정성적 예측을 추가적으로 제시하였고, 사업의 특수성과 평가항목이 갖는 일반성을 명확히 구분하여 의사결정 과정에서 주관적인 요소를 최소화하였다. 또한, 평가항목별 사업전후의 환경성을 비교, 검토함으로써 실제 사업추진 과정에서 개발로 인한 부정적 영향의 사전예방에 도움을 줄 수 있을 것으로 판단된다.

  • Transit Oriented Development(TOD) has been the dominant paradigm for urban development. The traditional approach to the development of urban rail station areas demonstrates apparent weaknesses when it comes to compact and mixed-use types of development for these stations. Thus, the objective of this study is to derive evaluation indicators with which to assess urban rail station areas using TOD planning elements. A focus group interview was conducted to explore TOD planning elements. In order to examine the level of TOD to be achieved, an AHP technique was utilized to analyze the importance of several variables. Z-scores and Re-scores were applied to derive the values for the stations. The Variables related to the land use type, mixed use, floor area, and public transit were found to be the major contributing factors to the achievement of TOD in urban rail station areas. The results of this study show that the level of TOD achievement varies according to the major land use, density, accessibility, and mixed-use planning elements.

  • Recently, due to problems with subway and bus operations, a need has emerged for a solution such as the introduction of an Advanced Transit System. In several municipalities, systems have been introduced using light rail as AGT urban aesthetics construction. There is high inhibition and civil cases are delayed by more environmentally friendly and accessible remedies. For the purpose of this study, Changwon city would be transformed to have an environmentally friendly transportation system such as a tram with an overview. Features, advantages, and disadvantages are analyzed, and systems are established the existing public transport routes by transfer system. Changwon city's tram plan is first step in open in year 2018, and second step with the opening goal of the year 2021, and the total line length of 33.9 km, the station will be built in the 38 locations. and also in 2011 a feasibility study, evaluated a low economic as B/C to 0.88, but it evaluated the high value of the policy analysis as AHP to 0.502. However, introduction of a tram project that should precede the as following condition. The first step in Changwon city's tram plan would be as follows : The introduction of the tram system would demand traffic management along with a restructuring of the bus system, and the tram system would be selected for domestic realities. Secondly, the introduction of trams would comprehend the advanced traffic composition in accordance with the consensus of the citizenship, and a legal system should be established for the introduction of the trams.

  • The current recommendation systems have problems including the difficulty of figuring out whether they recommend items that actual users have preference for or have simple interest in, the scarcity of data to recommend proper items due to the extremely small number of users, and the cold-start issue of the dropping system performance to recommend items that can satisfy users according to the influx of new users. In an effort to solve these problems, this study implemented a movie recommendation system to ensure user satisfaction by using the Fuzzy-Analytic Hierarchy Process, which can reflect uncertain situations and problems, and the data partition algorithm to group similar items among the given ones. The data of a survey on movie preference with 61 users was applied to the system, and the results show that it solved the data scarcity problem based on the Fuzzy-AHP and recommended items fit for a user with the data partition algorithm even with the influx of new users. It is thought that research on the density-based clustering will be needed to filter out future noise data or outlier data.

  • The purpose of this paper is to select proposed waste facilities sites after consideration of relative importance of siting factors. From the literature review we have established the siting factors affecting selecting waste facilities sites, and constructed hierarchy of siting factors to evaluate the relative importance of the factors using Analytical Hierarchy Process(AHP). After mail surveying of expert group, we have analyzed the relative importance of siting factors affecting waste facilities. We have constructed Geographic Information System(GIS) of raster type, based on seventeen theme maps of siting factors on waste facilities, to select the proposed waste facilities sites after consideration of the relative importance of the siting factors for Gyongsan city, in Korea. After applying linear combination method, and factor combination method to overcome the methodological limitations of land suitability analysis, we have found five proposed sites, where intersected with proposed sites obtained from the two methods. From this research we have found that 1) methodologically, using GIS for selection of proposed waste facilities sites turned out to be highly useful, 2) application of relative importance of siting factors and two methods of land suitability analysis in selection of proposed waste facilities sites are pertinent enough to provide valid and reliable results, and 3) the research methods and approach employed in this research will be highly useful in site selection of other major facilities.
