The uncertainty in the relative weights of a pairwise comparison matrix n Multi-attribute Decision Making (MADM) is caused by imprecise preference information of decision maker. In this paper, it is shown how weight of attributes can be derived from the pairwise comparison matrix with interval pairwise comparison. The preference information of each pair of attributes with a point pairwise comparison is combined with an interval pairwise comparison in order to estimate a point pairwise comparison for a pair of attributes with the imprecise preference information. A numerical example shows the suggested procedure for deriving weights of attributes.

This study intended to provide more refined information on color preferences by systematizing the concept of the color preference(general color preference, apparel color preference) and revealing different trends in the color preference and the actual possession of apparels. We collected data from 303 females in the ages between 20 and 40 in Seoul and analyzed by paired t-test. The results were as follows: 1. The analysis on general color preference, apparel color preference, and apparel possession color revealed that the cold colors such as blue and violet marked higher, and the warm colors such as yellow and orange marked lower in general color preference. For apparel color preference, neutral and brown were among the highest and the rest of the colors were in the same trend as general color preference. Apparel possession color showed defined accordance with apparel color preference. In terms of tones, pale tone marked the highest in general color preference and was followed by vivid, dull, and dark tones in decreasing order. For apparel color preference, pastel, dul1, and dark tones were among the highest. 2. Comparison between general color preference and apparel color preference in terms of hue showed that, except for orange, every hue showed disagreement in general color preference and apparel color preference. Neutral and brown hues marked higher in apparel color preference than in general color preference where as a]1 the other hues marked higher in general color preference. Comparison between apparel color preference and apparel possession color in terms of hue revealed that in most hues, apparel possession color was lower than apparel color preference. In terms of tones, vivid and pale tones marked higher in general color preference than in apparel color preference while dull and dark tones marked higher in apparel color preference than in general color preference.

This study intend to research color preferences about innerwear(specially brassiere) and draw a comparison of color preference's differences among the Korea, China and Hong Kong. The subjects of study are female students of universities in Korea, China and Hong Kong. The data analysis was done with the statistical treatment in SPSS 14.0, and the results are as follows. Female students of universities in Korea, China and Hong Kong are distinguished from wearing color and preference color of innerwear. Korea and China female students prefer skin color to the other color but most of Hong Kong female students prefer black color. In case of red color, Korea female students don't select a red color as a preference color but even if some students select a red color, China and Hong Kong females prefer a red color. The traditional color opinions of Korea, China and Hong Kong are the same as a Yin-Yang School. But these days they have different color opinions because of cultural, political and ideological elements. Korea females like skin and white colors because these colors don't appear on the outwear surface. Korean have an inclination toward conservatism and use the color according to ideological and deceptive orders of the Confucianism. Hong Kong have a different color preference from China because they have chances of receiving the other cultures for example United Kingdom, Japan and so on.

딥러닝 기술의 발전에 따라 학습을 통해 선호도 랭킹 추정을 하기 위한 다양한 연구 개발이 진행되고 있으며, 웹 검색, 유전자 분류, 추천 시스템, 이미지 검색 등 여러 분야에 걸쳐 이용되고 있다. 딥러닝 기반의 선호도 랭킹을 추정하기 위해 근사(approximation) 알고리즘을 이용하는데, 이 근사 알고리즘에서 적정한 정도의 정확도를 보장할 수 있도록 모든 비교 대상에 k번 이상의 비교셋을 구축하게 되며, 어떻게 비교셋을 구축하느냐가 학습에 영향을 끼치게 된다. 이 논문에서는 크라우드 소싱 기반의 딥러닝 선호도 측정을 위한 쌍체 비교 셋을 생성하는 새로운 알고리즘인 k-disjoint 비교셋 생성 알고리즘과 k-체이닝 비교셋 생성 알고리즘을 제안한다. 특히 k-체이닝 알고리즘은 기존의 원형 생성 알고리즘과 같이 데이터 간의 연결성을 보장하면서도 안정적인 선호도 평가를 지원할 수 있는 랜덤적 성격도 함께 가지고 있음을 실험에서 확인하였다.

This study investigates which sound quality indices except SPL raise annoyance response. For investigation, auditory perception experiments for road traffic noise with identical linear SPL were performed by Paired Comparison Method. The numerical results of a Paired Comparison experiment express relative preference about annoyance. So that these relative preference scores are to be correlated to sound quality indices, which are absolute, a transformation is required to go from the relative domain to an absolute and linear scale of preference. The results of the transformation will be the 'merit values,' which quantifies the annoyance(in this case) of the road traffic noise on a linear scale. Using multiple regression, a formula is established that can calculate predicted merit values. Furthermore, This investigation offers a method selecting sound samples that represent various sound quality indices values to use experiment.

Engineering design can be viewed as a decision making process, which involves the nonlinear tradeoffs task among the multiple conflicting attributes and considers the robustness of design. In order to obtain best engineering design, methodology for accurate assessment of his/her preference about the multiple attributes is required. Conventionally, intuitive procedures based on lottery questions are used to elicit the designer's preference structure: however, they can lead to inconsistent and inexact preference results due to the rank reversal problems derived from the designer's big cognitive burden. In this paper, alternatively, a design methodology based on multiattribute utility function through the pairwise comparison among alternatives is presented. The proposed procedure is applied to an actual injection mold design with the aid of the CAE simulation and the result is discussed.

A paired comparison which is a method of comparative judgements is widely used to increase the amount of information transmitted to human sense organ. In this study, a paired comparison method is proposed for the discrimination capacity and preference analysis of non-skilled sensory inspectors. We consider on order effect, that is, difference of evaluation occurred as a result of sample presentation by random order. The purpose of this paper is to determine a sample with the highest preference degrees by analyzing a discrimination capacity and evaluating preference degrees of sensory inspectors. An analysis of a discrimination capacity is bared on the capacity index obtained by an eigen-vector method and an evaluation of preference degrees is performed by a significance test.

The purpose of this study was to investigate desirable width / height ratio of enclosed space and to offer basic information for the design of enclosed spaces. The data of this study were gathered from the experiment through simulation. Photographic sampling of 7 campus sites located in Kwanak campus of Seoul National University and slides of perspective drawings of enclosed spaces with various D/H ratio (12, 1, 2, 4, 6, 9, 12)were used for simulation. A response format was made using the method of paired comparison and students from various departments were randomly selected for evaluation. In the method of analysis of data Thurstone's equation of Comparative Judgement was used for calculating preference score. A1so non-linear regression analysis was used for finding out relations between preference and D/H ratio. The other method of data analysis were correlation, Chi - test. And the results were summarized as follows. 1. In sketch simulation the ratio of D/H 4 got the highest preference store. This result suggests that desirable D/H ratio of enclosed space is D/H 4. And at the lower range of D/H ratio, as ratio increases, the preference score increases. At the higher range of D/H ratio, however, as ratio increases, the preference score starts to decrease from the cardinal point of D/H 4. 2. In campus photograph simulation preference is influenced by slope, elevation change of floor, trees, lawn area, familiarity, space arrangement, and exterior shape of building besides D/H ratio. 3. The preference virtue was not significantly affected by order effect. This result suggests that order effect can be ignored in the study of visual preference. 4. There are so many factors related to preference that it is difficult to explore those factors without scientific information based on scientific method. We must carry out study for scientific approach of planning and design based on precise, complete simulation technique.
