✦ Synopsis

Ž

. Quality Function Deployment QFD has been used to translate customer needs and wants into technical design Ž . requirements in order to increase customer satisfaction. QFD utilizes the house of quality HOQ , which is a matrix Ž . providing a conceptual map for the design process, as a construct for understanding Customer Requirements CRs and Ž . establishing priorities of Design Requirements DRs to satisfy them. Some methodological issues occurring in the conventional HOQ are discussed, and then a new integrative decision model for selecting an optimal set of DRs is presented using a modified HOQ model. The modified HOQ prioritization procedure employs a multi-attribute decision method for assigning relationship ratings between CRs and DRs instead of a conventional relationship rating scale, such as 1-3-9. The proposed decision model has been applied to an indoor air quality improvement problem as an illustrative example.
