摘　　要：结合模糊数据包络分析(data envelopment analysis,DEA)提出了基于独立子系统的模糊DEA模型。研究结果发现提升子系统效率能够达到改善整体系统效率的效果。以5所高校系统效率评估为例,进一步阐述了整体系统与子系统之间的效率关系,诠释了所提模型的可行性及实用性。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.
