Abstract :
To evaluate product design schemes with qualitative information on indices weights, we introduce data envelopment analysis (DEA) and analyze its disadvantages in processing qualitative weight information, and then propose a modified DEA model. In the method, first, evaluation indices are normalized. Secondly, based on the normalized indices and qualitative weight information, we present a DEA model with outputs only and preference information to calculate synthesized attribute values of schemes. Experiment results show that the method can not only evaluate products with complete and incomplete qualitative weight information, but also with entirely unknown weight information.
