摘　　要：基于交叉效率概念,遵循自评与互评相结合的原则,提出三参数区间交叉效率DEA评价方法。运用不同的赋权策略,获得用最优效率值、最劣效率值和最可能效率值描述的决策单元三参数区间交叉效率值。该效率值能更全面合理地反映决策单元效率值可能的取值情况和实际评价问题的特点,利用三角模糊数期望值排序方法可以对该效率值进行比较排序。算例说明该方法具有可行性和有效性。Based on the concept of cross efficiency and the principle of self-evaluation and peer-evaluation,a method for analyzing three-parameter interval cross efficiency is proposed by using data envelopment analysis（DEA）.With different weighting strategies,the optimal efficiency score,the worst efficiency score,and the most possible efficiency score are obtained.These scores comprehensively and rationally reflect all possible efficiency scores for the evaluation problem.Then,by using the expected value of triangular fuzzy number,this interval cross efficiency can be properly ranked.A numerical example is given to illustrate the feasibility and effectiveness of the proposed method.
