Data Envelopment Analysis is used to determine the relative efficiency of Decision Making Units as the ratio of weighted sum
of outputs by weighted sum of inputs. To accomplish the purpose, a DEA model calculates the weights of inputs and outputs
of each DMU individually so that the highest efficiency can be estimated. Thus, the present study suggests an innovative method
using a common set of weights leading to solving a linear programming problem. The method determines the efficiency score
of all DMUs and rank them too. 相似文献
