Abstract :
One of the drawbacks of Data Envelopment Analysis (DEA) is the problem of lack of
discrimination among efficient Decision Making Units (DMU) and hence yielding
many numbers of DMUs as efficient. The main purpose of this paper is to overcome
this inability. In this paper, we explain new methods based on stability ranges for
weights of inputs and outputs, these weights are the weights, that DMUs remain
efficient. For illustration numerical example is given.
