Super-efficiency based on a modified directional distance function

Chen, Yao; Du, Juan; Huo, Jiazhen - In: Omega 41 (2013) 3, pp. 621-625

The problem of infeasibility arises in conventional radial super-efficiency data envelopment analysis (DEA) models under variable returns to scale (VRS). To tackle this issue, a Nerlove–Luenberger (N–L) measure of super-efficiency is developed based on a directional distance function....
