value efficiency analysisin different technologies

One way to apply decision - making preference information in the efficiency evaluation process in data envelopment analysis is to use the value efficiency approach . in this paper , we first describe the concept of value efficiency and use the directional distance function to calculate the efficiency . by choosing different directions , we calculate the value efficiency scores in different orientations , and obtain value efficiency scores in constant and variable return to scale and ( free disposal hull ) fdh technologies by developing the directional distance function model . we apply the approach presented in the paper to the bank dataset in the following and show that we can obtain value efficiency scores for other banks by using bank management opinion in choosing the most valid and efficient branches as must prefer solution ( mps ) units . finally , we present the results of the research .
