摘要
当投入和产出数据为区间数时,传统的DEA模型转化为区间DEA模型。首先建立了求解每个DMU的最高效率值和最低效率值的确定型DEA模型,从而求得每个DMU的区间效率值。然后按区间效率值将所有决策单元分为三类,即区间DEA有效、区间DEA部分有效和区间DEA无效。将文中方法应用于10省建筑业的效率评估和预测之中,结果较传统的DEA模型更具柔性、更为合理。
<Abstrcat>When the inputs and outputs are intervals, the original DEA model is transformed into interval DEA. Accurate DEA models of obtaining the highest and lowest efficiency score of each DMU are proposed firstly. As a result, an interval efficiency score of each DMU is gotten. Based on this, all the DMUs are classified into three types, which are interval DEA efficient, interval DEA partly efficient and interval DEA unefficient. Finally, on the basis of the interval data obtained by forecasting the construction industries of certain ten provinces, this method is applied in evaluating and forecasting efficiency on the construction industries. The result is more flexible and resonable than the original DEA model.
