Description

Abstract
"在資料包絡分析的應用中,投入或者產出變數可能是整數。因此這些整數值變數的投影應該 是整數。然而,傳統的資料包分析模型,例如CCR或BCC模型不能處理這樣的狀況。Kuosmanen and Kazemi (2009) 提出了一個模型可以找出整數值變數的整數投影。然而,此模型所找出的 整數投影可能不是整數型柏拉圖最佳。近期,Chen et al. (2015)提出另一個模型。此模型可能 會無可行解,如果要求非整數值變數其投影必須為整數時。在本研究計畫中,我們將提出一 個兩階段模型克服以上缺點。""在資料包絡分析的應用中,投入或者產出變數可能是整數。因此這些整數值變數的投影應該 是整數。然而,傳統的資料包分析模型,例如CCR或BCC模型不能處理這樣的狀況。Kuosmanen and Kazemi (2009) 提出了一個模型可以找出整數值變數的整數投影。然而,此模型所找出的 整數投影可能不是整數型柏拉圖最佳。近期,Chen et al.

Therefore, the projections of those integer-valued variables should be integers. However, traditional DEA models such as CCR or BCC cannot deal with such situation. Kuosmanen and Kazemi (2009) propose a model which can identify the integer projection for integer-valued variables. However the projection identified might not be integer valued Pareto optimal. Recently, Chen et al. (2015) propose another model which might not be feasible when the projection of a non-integer-valued variable is required to be integer. In this project, we are going to propose a two-stage model to overcome these issues."
