Technologies ranking in the presence of both cardinal and ordinal data

Ranking of technologies is an important phase for technology transfer. To rank the best technologies in the presence of both cardinal and ordinal data, this paper proposes an innovative approach, which is based on imprecise data envelopment analysis (IDEA). The objective of this paper is to propose a comprehensive reference that discusses the use of IDEA in technology ranking. A numerical example demonstrates the application of the proposed method.
