An integrated supplier selection methodology incorporating QFD and DEA with imprecise data

Highlights：

• A novel fuzzy decision framework that integrates QFD and DEA is presented for supplier selection.

• The proposed approach incorporates imprecise data into the analysis using linguistic variables.

• Both relationships among product features and supplier attributes (SAs), and dependencies among SAs are considered.

• FWA is used to compute the lower and upper bounds of the weights of SAs utilizing the data from the HOQ.

• DEA is implemented using weights of SAs computed by FWA and supplier ratings with respect to SAs.
