 λ-퍼지측도를 사용한 질적, 양적혼합품질특성을 가진 부품의 군집화 김정만1, 이상도2 1경북산업대학교 산업공학과2동아대학교 산업공학과 The Clustering of Parts with Qualitative and Quantitative Quality Properties using λ-Fuzzy Measure Jeong-Man Kim1, Sang-Do Lee2 1Dept. of Industrial Engineering, Kyungpook-Sanup University2Dept. of Industrial Engineering, Dong-A University ABSTRACT In multi-item production system, GT(Group Technology) is used effectively in order to cluster various parts into groups. GT is based on clustering parts which have similar features, and these features are classified into two properties, namely crisp(quantitative) feature and fuzzy(qualitative) feature. Especially, many difficult problems are often faced that have to evaluate the properties of parts with the crisp and fuzzy feature together. As the basis of determining the similarity of inter-parts, in this method, one aggregate value is calculated on each part. However, because the above aggregate value is only gained from simple additive weighted sum, there is one problem in this method that has been handled the combination effect of inter-parts. For these reasons, in this paper, a proposed method is suggested for representing combination effect in order to cluster parts that have crisp and fuzzy properties into groups using ${lambda}$-fuzzy measure and fuzzy integral.
