摘要

Stochasticity and stochastic variations in inputs and outputs represent a form of uncertainty. In this sense, incorporating stochastic variations of the input/output data into DEA models is an important subject that has received considerable attention over the past two decades. The underlying theories of DEA under a stochastic environment are presented in this chapter. This allows us to replace terms such as “efficient” and “inefficient” with “probably efficient” and “probably inefficient”, respectively.
