A Novel Model for QFD of Categorical Data Using Target Based HOQ

Abstract—Quality Function Deployment (QFD) is an effective methodology for analysis of customer requirements in order to improve the performance of a service. In this paper A Novel Model for QFD of Categorical Data using Target based House Of Quality (NQTHOQ) model is proposed. The categorical data is considered for QFD analysis. Given model minimizes the analyst’s opinion to compute some of the parameters that constitute HOQ of QFD. The association rules are used for realizing relationship matrix between customer requirements and engineering characteristics. The chi-squared attribute evaluator is used to determine variable importance of each customer requirements based on target. The novel concept of THOQ is built using association rules and variable importance to compute importance rank of HOQ which constitute QFD. Index Terms—QFD, VOC, HOQ, Chi-squared attribute evaluato
