This order relation expresses the decision-makers satisfaction degree based on which the inequality constraints of interval DEA can be transformed into constraints with exact coefficients.
定义了一种反映决策者满意度的区间数序关系,基于此将区间DEA中的区间不等式约束转化为确定型约束。
Based on this, all the DMUs are classified into three types, which are interval DEA efficient, interval DEA partly efficient and interval DEA unefficient.
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。
According to whether the decision-makers subjective judgment is needed, the method of solving interval DEA is classified into the subjective method and objective one.
根据是否需要决策者的主观判断,将区间DEA的求解方法分为主观方法和客观方法。
