퍼지추론모델에 의한 계층적관능품질구조를 가진 제품의 만족도평가 = Sensory Evaluation on Degrees of Satisfaction of Product With Hierarchical Quality Structure Using Fuzzy Inference Model

다국어 초록 (Multilingual Abstract)

In the quality evaluation of product with sensory characteristics, there is a case that these characteristics are connected one another from the lowest rank to highest one as hierarchical structure. In this case, considering the relative importance and ralation of these characteristics, we have to do overall evaluation by means of input informations of the lowest rank. In this paer, an attemp is made to develop a synthetic analytical method of hierarchical structure based on the fuzzy infrence model.
At first, the evaluation is performed through such as linguistic variables as "good", "ordinary", "bad", etc.. Information of the linguistic variables is transmitted from the input events to the top event, in which weightening is taken into account on the evaluation of each element. The final result, which is obtained at the top event in the form of membership function, is interpreted by use of the concept of pattern recognition.
