Super-efficiency in stochastic modified directional distance function-based model

This essay addresses super-efficiency issue based on modified directional distance function-based(modified DDF-based) model in stochastic data envelopment analysis. The modified DDF-based super-efficiency model is developed in stochastic data envelopment analysis, and its deterministic equivalent, also, is derived which is a nonlinear program. Furthermore, it is shown that the deterministic equivalent of the stochastic super-efficiency model can be converted to a quadratic program.
