An assessment of sustainable house using FST-QFD-AHP multi-criteria decision-making approach

The proposed method is used in the selection of sustainable residential house using relative benchmarking (against other sustainable residential housing projects) as well as absolute benchmarking (against an ideal residential housing), which offers a tangible means by which to evaluate residential house. In light of the heterogeneous capabilities of sustainable residential housing project, the decision-makers can objectively assess each residential house interface and detect when corrective action may be necessary. A sample sustainable housing project as a strategic tool to facilitate marketing decisions system design is used to illustrate the proposed approach. Implementation results show that the proposed approach is able to eliminate the burden of quantifying qualitative concepts in sustainable quality function deployment (QFD) and model the customer variability and the design team's preference. Due to its easiness in articulating preferential information, our approach can reduce the cognitive burden of QFD planning team and give a practical convenience in the process of QFD planning.
