  • This article is concerned with choice-based conjoint analysis versus rating-based and ranking-based conjoint analysis. Choice-based conjoint analysis has a definite advantage in that the respondent's task of choosing the most preferred profile from several competing profiles adequately mimics consumer marketplace behavior. It is crucial to design the choice sets appropriate for the choice-based conjoint. Thus, this article suggests a new method to design the choice sets that are well-balanced. It augments the balanced incomplete block design and then obtains the dual design of the result to accommodate various numbers of profiles. In consequence, the choice sets designed by the new method have the desirable characteristics that each profile is presented to the same number of respondents, and pairs of any two distinct profiles occur together in the same number of choice sets. The balancing of the design increases the efficiency of the conjoint analysis. In addition, the pair-comparison scheme can improve the quality of data through the identification of contradictory responses.

  • PURPOSES : This study was initiated to estimate the utilities of usage attributes of BRT and Bimodal Trams using a conjoint analysis method in order to identify the important features pertaining to the use of BRT and Bimodal Trams. METHODS : For this purpose, important attributes and those level in the use of BRT and Bimodal Trams in the city of Sejong were identified. Next, a profile questionnaire pertaining to BRT and Bimodal Trams was designed for the conjoint analysis, and a survey was conducted in the city of Sejong. Using SPSS software, conjoint analysis was performed to identify the important attributes vis-$\acute{a}$-vis the use of BRT and Bimodal Trams in the city of Sejong. Finally, the utilities for individual attributes were calculated based on the models estimated by the conjoint analysis. RESULTS : The results of the conjoint analysis were used to identify the important attributes. With regard to the usage of BRT, users indicated that fare was the most important attribute with the highest utility. In the case of Bimodal Trams, the users indicated that the number of seats and internal environment were the most important attributes with the highest utilities. CONCLUSIONS : Based on the results of the conjoint analysis, the important attributes pertaining to the use of BRT and Bimodal Trams in the city of Sejong were identified. Our study indicates that BRT in the city of Sejong needs to be upgraded to improve the utilities of the important attributes. Currently, Bimodal Trams has not been introduced completely in the city of Sejong. However, in the future, when the introduction of Bimodal Trams is completed, the important attributes should be emphasized in order to improve the quality of its service.

  • Recently, consumers are tend to purchase the user-centered designed product using interface enginnering and human factors techniques. Therefore, it is important that the designer's requirements should be analyzed focused on the human machine interface. This paper described the interface usability evaluation technique(suvjective evaluation) for the interface between user and product. This methodology is the integrated interface usbility evaluation method AHP and Conjoint Analysis. AHP(Analytic Hierarchy Process) is a multicriteria decision model to give priority after expressing hierarchically for decision making problem. Conjoint Analysis enduavors to unravel the value, or partworths, that consumers place on the product or service's attributes from experimental subjects' evluation of profiles based on hypothetical products or services. A new usability test methodology proposed by this paper includes techniques jointed both consistency test by AHP and experimental subjective evaluation of profiles by Conjoint Analysis for evaluating the user's emotion and impression.

  • 컨조인트 분석은 경영학에서 제품 대안들에 대한 소비자의 선호 정도로부터 소비자가 각 속성에 부여하는 상대적 중요도와 각 속성수준의 효용 부분가치를 추정하는 분석방법이다. 본 논문에서는 초등학교 컴퓨터 특기 적성 교육 과목들에 대한 학생들의 선호정도를 컨조인트 분석을 통해 알아보았다. 그 과정에서 특별히 인공 신경망 분석을 부가적으로 수행하면 보다 많은 유용한 지식을 얻을 수 있음을 중점적으로 다루었다.

  • 기업의 마케터들은 어느 때보다 빨라진 소비자 욕구의 변화와 경쟁제품 출시에 대응하여 신제품 성공의 확률을 극대화시키려 노력한다. 소비자의 욕구에 맞는 신제품을 개발하기 위해 활용되는 기법 중 하나가 컨조인트분석이다. 본 논문은 컨조인트기법 중 가장 널리 이용되는 전통적 컨조인트분석과 선택형 컨조인트분석의 예측력을 비교하는데 초점을 맞추었으며 그 대상으로 병원산업을 선택하였다. 모형간 예측력 비교를 위해 전통적 컴조인트분석과 선택형 컨조인트분석 중심으로 4가지 모형을 선정하였다. 분석결과, 전통적 컨조인트와 선택형 컨조인트를 결합한 혼합형 컨조인트기법의 예측력이 가장 높은 것으로 나타났으며, 각 모형에서 추정된 모수간의 일관성도 높은 것으로 나타났다.

  • This article has tried to identify the preferred subjects of after school computer educations in elementary schools by means of the conjoint analysis. We surveyed the fourth, fifth and sixth grade students from the three schools in Seoul. It has been found that graphic related courses are most preferred, though such courses are taught in public schools. Based on this research, we propose a new curriculum for after school computer education.

  • This study is about designing mobile phone display in consideration of elder people's preferences by reason of their optical weakness. The research is closely connected with designing user-friendly interface by considering user characteristics. The criteria for first experiment are font sizes, font types, line spacing and background colors. With the experiment result, relative importance of each attribute and subjective preference are investigated by conjoint analysis. Secondly, an optimal display design for elder people is presented by response surface method on the basis of the result of conjoint analysis, other statistical analyses, and user interviews.

  • In order to point out the best utility of a product (or a service), marketers need to clearly understand and measure the preference of the consumers. Among numerous marketing analysis techniques, the conjoint analysis is one of the popular tools for market research. One of the issues with this tool is the lack of feedback for the respondents. This paper proposes personal stepwise conjoint analysis based on an interactive Web-questionnaire allowing respondents to receive a diagnosis of their evaluation and giving the possibility to reconsider their evaluation. To validate our proposal, experimentation with forty-two respondents is also demonstrated. Experimental results, potential modifications and improvements are detailed in this paper.
