쌀밥의 관능검사 결과분석에 퍼지추론을 적용하였다. 관능검사시 쌀밥의 관능적 요인인 조직감, 맛, 냄새 및 외관이 각각 쌀밥 기호도의 결정에 역할하는 정도(기여도)를 매우중요, 요, 보통, 경시, 매우경시의 택일으로서 평가하도록 하였으며, 주어진 쌀밥 시료에 대하여 각관능척 요인의 기호도를 매우우량, 우량, 보동, 불량, 매우불량의 택일로서 평가하도록 하였다. 퍼지추론 과정으로 먼저 전체기호도에 대한 일반적인 관능적 요인의기여도를 추론하고, 시료에 대한 관능적 요인의 기호도틀 추론된 기여도와 퍼지합성하여 결과적으로 전체기호도를 추론하였다.
Fuzzy reasoning was applied to sensory evaluation of cooked rice. A sensory attribute diagnostics was done in terms of tour kinds of attributes-texture, taste, odor and appearance which determine overall palatability. First, rating for the contribution level of each attribute to the overall palatability was asked as one of five scales-very important, important, moderate, slight and very slight. Secondly, the preference level of each attribute for a cooked rice sample was asked as one of five hedonic scales-excellent, good, fair, poor and very poor. Thirdly, the results of the scales were converted into fuzzy values and operated by fuzzy reasoning. Finally, the contribution and preference levels of the attributes were composed to infer the overall palatability of cooked rice sample.
