A kind of dominance chance constrained DEA model is provided in this paper based on the DMUs' stochastic inputs/outputs and DM's preference structure. The stochastic DEA efficiency of DMU is defined and the necessary conditions for efficiency evaluation are discussed. With the single random factor assumption, the stochastic DEA problems can be solved via the method of chance constrained programming and the goal programming theory. Finally, a case is given to point out that dominance chance constrained DEA model has a promising use in practice.
