First aim of this study is to investigate consumer's actual value for environment related performance of house by using three different method, Ranking, Analytical Hierarchy Process (AHP) and Conjoint Analysis method. Second aim is to estimate consumers' monetary value about environment related factor through Marginal Willing to Pay(MWTP), and third aim is to find out the difference of values between the groups classified according to respondents' characteristics. A questionnaire survey was carried out in Seoul in order to clarify the preference and monetary value of four selected attributes. They are environmental performance, residents' health, home automation and increase of floor area. As a result, people showed high values in the order of health, environmental consideration, increase of floor area and home automation. Moreover, it was found out that MWTP for environmental performance and health are higher than market price. In addition, the group of high age and group of female showed high values for the reduction of $CO_2$ emission

The objective of this paper is to analyze consumers' consumption behavior of environment-friendly mandarin and attributes of mandarin in Korea. It is also to measure consumers' marginal willingness to pay by the attributes of mandarin and to estimate the market-share by products of mandarin from the data surveyed by a survey research company. The questionnaires for consumers were given randomly by interview to 500 married women lived in Seoul and to 200 wholesaler in Seoul, Busan, Daegu, Kwangju. The conjoint analysis method was used to analyze consumers' preference and suggest several implications for the rational production and marketing policy of mandarin.

We research a competitive advantage of telecom bundling package of three mobile telecom company by figuring out utility that consumers perceived and focused on mobile telecom and high speed internet in one bundled package. As a method, conjoint analysis was applied. And in conclusion, consumers considered retaining mobile telecom company as the most important factor to them and branding as the following important one when one bundled package of telecom service is provided in total market. When the market is divided into two submarkets and the second largest submarket is analyzed personal bundled package was most important and three year agreement with a stipulated discount has the highest utility. As a result of this analysis, mobile telecom company managers need to organize bundled package after consideration of their current position and brand power in the market, and then devise proper market strategy

The purpose of this study is to analyze the demand for telemedicine and telehealthmanagement services, which are key elements of home based u-health. The conjoint analysis, which is a conventional method for demand analysis for newly introduced products, is employed, utilizing the survey data on 500 seoul citizens. Further, multivariate probit model is used to estimate the demand. The result shows that the demand for telemedicine services is greater than that of telehealthmanagement services. Further, home-based u-health services will play a role as a complementary for face-to-face medical treatments, rather than a substitute. Meanwhile, the demand for home-based u-health services is found to be very sensitive to price.

Bioinformatics service is very new and emerging in market that provides information such as whether or not occurrence of a particular disease through the base of DNA(Deoxyribonucleic Acid) & RNA(Ribo Nucleic Acid) sequence analysis. Recently, interest growing rapidly in utilization of the industrial purpose, but provision of commercialization like pricing and service packaging is not enough to go to market. For go-to-market, firstly refine the services and perform cost calculation of services in cost-plus method then estimate consumer utility by conducting conjoint analysis. Collectively, with cost and consumer utility result, optimal service price can be calculated.

In this paper, we propose a constrained optimization model for conjoint analysis (a preference decomposition technique) to improve parameter estimation by restricting the relative importance of the attributes to an extent as decided by the respondents. Quite simply, respondents are asked to provide some pairwise attribute comparisons that are then incorporated as additional constraints in a linear programming model that estimates the partial preference values. This data collection method is typical in the analytic hierarchy process. Results of a simulation study show the new model can improve the predictive accuracy in partial value estimation by ordinal east squares (OLS) regression.

Personal Air Vehicle is expected to be a promising solution to relieve traffic congestion using urban airspace. The development of related technologies such as materials or batteries has been accelerated. In addition, commercial transportation services are being prepared. When fierce competition begins in the PAV market, even technologically superior products will disappear without choices by consumers. Therefore, demand factors should be reflected in PAV development to enhance competitiveness. In the paper, values were estimated for the major technological attributes of PAV. Stated preference data were collected through a survey, and the conjoint method and ordered probit model were adopted. Thereafter, it was confirmed that the value would be high in the order of dual mode, drone-type appearance, and noise reduction. Some R&D strategies were proposed based on this.

로지스틱회귀분석은 고객관계관리나 신용위험관리 등의 분야에서 많이 사용되는 기법인데, 이러한 분야에서의 로지스틱회귀모형에는 연관성이 높은 설명변수들이 다수 포함되어 다중공선성의 문제를 유발하는 경우가 있다. 다중공선성이 존재하는 상황에서 최우추정량은 심각한 결함을 갖는다는 사실은 잘 알려졌다. 이 문제를 해결하기 위하여 로지스틱주성분회귀를 연구하되, 분석상의 주요 과정인 주성분 선정을 위한 방법을 새롭게 제안하였다. 추정량의 분산을 최소가 되게 하는 상태지수 값을 측정하고, 이 값에 영향을 미치는 주요 요인들을 컨조인트분석에 의해 파악하여 주성분 선정기준을 결정하는 모형을 구축하였다. 제안된 방법은 다중공선성 문제를 적절히 해결하면서도 모형의 적합성을 향상시킨다는 사실이 모의실험을 통하여 확인되었다.

신제품 개발 과정에 있어 시장 요인과 기술 요인의 통합적 설계가 강조되면서 마케팅 영역(marketing domain)과 제조 영역(manufacturing domain)의 경계면(interface) 사이의 의견을 균형 있게 조정, 수렴해 주는 경계 시스템(interface system)에 대한 연구의 중요성이 커지고 있다. 본 연구에서는 이러한 배경을 토대로 각 영역(domain)에서 대표되는 신제품 파라미터 설계 방법인 컨조인트 분석과 다구찌 방법을 비교함으로써 두 영역의 신제품 개발 관점을 대비시키고 나아가 신제품 파라미터 설계를 위한 통합적 해결방안(integrated solution)을 제시한다. 그리고 도출된 방법론을 자동차 운전석 내부 설계 사례에 예시적으로 적용함으로써 유용성을 검증한다. 본 연구에서 제시된 방법론의 핵심적 특성과 차별적 의의는 기존의 연구들처럼 두 방법론을 선택하여 사용하는 것이 아니라 순차적으로 결합한 새로운 프로세스를 사용함으로 두 영역에서 발생하는 상충 관계(trade off)를 해결하여 고객의 효용도와 품질의 강건함이란 목적을 동시에 만족시키는 설계가 가능하다는데 있다. 나아가 신제품 개발 목표와 기업의 전략에 따라 분석의 순서와 설계수준의 크기를 조정할 수 있는 신축성을 확보할 수 있다는 점도 제시할 수 있다.

정보 자산에 대한 위험 분석은 주로 한국정보통신기술협회나 국제표준화기구의 표준에 따라 이루어지고 있다. 그 과정은 자산분석, 위협분석, 취약성분석, 대응책분석의 순서로 이루어져있다. 이 과정은 분석 대상, 즉 자산을 명확히 파악하는 것부터 시작된다. 기존의 방법은 그 대상을 물리적 자산에 따라 분류하는 것이 일반적이다. 한편, 국제결제은행 규약이 제시하는 방법에 따르면 위험 분석의대상을 운영에 따른 분류를 통해 규명하게 된다. 본 논문에서는 물리적 자산 중심의 기존 방법과 더불어 업무 중심의 분석 방법이 유용할 수도 있음을 보이고자 하였다. 컨조인트 분석 기법을 활용하여 상황에 따라 물리적 자산 중심의 방법과 업무 중심의 방법의 유용성의 차이를 예를 들어 분석하였다.
