Abstract :

Abstract:One of the drawbacks of Data Envelopment Analysis ( DEA ) is the problem of lack of discrimination among efficient Decision Making Units ( DMUs ) and hence yielding many numbers of Decision Making Units 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 Decision Making Units remain efficient. For illustration numerical example is given.
