  • 본 논문은 웹 상에서 음악을 듣는 사용자의 음악 취향을 평가 한 후, 취향에 맞는 인터페이스를 추천하는 시스템을 구현하였다. 초기 음악 취향 평가 단계에서는 평가 요소인 장르, 가수, 최신곡에 대한 사용자 데이터와 평가 요소에 대한 실험을 통해 얻은 중요도를 이용하여 퍼지측도.적분을 수행한다. 수행 결과 값이 높은 음악의 평가 요소에 의해 인터페이스를 추천하고, 추천된 인터페이스에 대한 선택 곡 수와 들은 시간으로 퍼지 추론을 통해 인터페이스에 대한 만족도를 평가한다. 평가된 만족도에 의해 중요도를 변경시킴으로써 사용자의 취향에 맞는 인터페이스를 제공하는 시스템 을 제안한다.

  • The fuzzy entropy is proposed for measuring of uncertainty with the help of relation between distance measure and similarity measure. The proposed fuzzy entropy is constructed through a distance measure. In this study, Hamming distance measure is employed for a distance measure. Also a similarity measure is constructed through a distance measure for the measure of similarity between fuzzy sets or crisp sets and the proposed fuzzy entropies and similarity measures are proved.

  • In this paper, we apply fuzzy theory in a discrete choice Contingent Valuation Method(CVM) in order for dealing preference uncertainty problem. Fuzzy membership function is used in an empirical analysis to estimate the willingness-to-pay(WTP) for the preservation of the endangered Asiatic Black Bear in Korea. The estimated WTP was about 9,090 Korea Won per household with 78 percent of confidence level. The advantage of applying fuzzy theory in the valuation method could be found in its ability to measure the confidence level of the estimated WTP.

  • All the visiting customers makes a queue and then can be served at an unoccupied server, in the queueing system of multi-server. The customer and server, however, have a conflictive feeling of satisfaction at all times. To solve the problem, in this paper, it is proposed that new design method of server number to maximize the satisfaction level of customer and server by the hzzy concept which is applied to the queuing system.

  • We construct the fuzzy entropy for measuring of uncertainty with the help of relation between distance measure and similarity measure. Proposed fuzzy entropy is constructed through distance measure. In this study, the distance measure is used Hamming distance measure. Also for the measure of similarity between fuzzy sets or crisp sets, we construct similarity measure through distance measure, and the proposed 려zzy entropies and similarity measures are proved.

  • For data analysis, fuzzy entropy is introduced as the measure of fuzziness, similarity measure is also constructed to represent similarity between data. Similarity measure between fuzzy membership functions is constructed through distance measure, and the proposed similarity measure are proved. Application of proposed similarity measure to the example of reliable data selection is also carried out. Application results are compared with the previous results that is obtained through fuzzy entropy and statistical knowledge.

  • This paper suggests an evaluation of risk level for damage of marine accidents in SRRs. This paper intoduces a concept of fuzzy logic with the plenty of related literature riview, fuzzy measure t-seminormed fuzzy integral and in the Korean SRRs of RCC and RSC. The methodology of this paper is max. min composition of fuzzy extensive principle, defuzzifiation is centroid of gravity methods. And final evaluation value using t-seminormed fuzzy integral. At the result, the evaluation of risk level is especially over serious for marine accident of Mokpo, Tongyoung, Yeosu SRRs.. This paper recommends that many rescue vessels and equipments need to the reduction of risk level about those.

  • The similarity measure is derived with distance measure, and the proposed similarity measure is proved to verily the usefulness. Conventional similarity measure which is constructed through fuzzy number and Center of Gravity(COG) is introduced, furthermore two similarity measures are compared through various types of membership function.
