New Methods Based on Distance Stability of Weights for Efficient DMUs in DEA

: 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 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 output. For illustration numerical example is given.
