Group multi-criteria design concept evaluation using combined rough set theory and fuzzy set theory

作者：

Highlights：

• An interval-based relative closeness index is proposed to rank design concepts.

• Design concepts with respect to quantitative criteria are evaluated with rough set.

• Design concepts with respect to qualitative criteria are evaluated with fuzzy set.

• The weights of criteria are obtained using the extent analysis method on fuzzy AHP.

• The results of design concept evaluation for our method are compared to TOPSIS.
