Variability Analysis in QFD: Prioritizing Engineering Characteristics

품질기능전개에서의 변동성 분석: 설계특성의 우선순위 결정

This paper proposes a new framework for variability analysis in QFD. The proposed framework considers the uncertainty of the information contained in the house of quality chart and analyzes the variability resulting in the outcome. A new framework provides a dominance index and a difference index for each pairwise ECs. The indices are helpful to evaluate priorities of each pairwise EC.
