Abstract:

Combined with Fuzzy DEA model, an extended fuzzy DEA model based on the independent multi-subsystems was built. It was found that the whole system efficiency can be improved by raising each subsystem′s efficiency. Efficiency evaluation of five universities was studied as a numerical example to illustrate the relationship between the whole system efficiency and subsystems′ efficiencies. And the practicability and feasibility of the model are demonstrated.

Key words: fuzzy DEA; multi-subsystems; efficiency evaluation
