摘要
提出了基于数据包络法的劣势效率评价模型,将其与现有数据包络模型结合起来,得到了一种综合评价决策单元相对有效性的效率评价方法.该方法分别从有利于被评决策单元和不利于被评决策单元的角度对被评决策单元的相对有效性进行研究,由此得到其综合有效性值,据此可以对决策单元进行排序.
Based on the DEA model, a new model is proposed in this paper to measure the relative efficiency of the assessed DMU(Decision making unit) through analyzing its disadvantages, and the results coming from the DEA model and the new one are combined to get each DMU's efficiency. By this way, we can compare the DMUs' efficiency rates and give their order.
