For many decision making problems under uncertainty, it is crucial to specify decision makers' risk preferences based on multiple stochastic performance measures. We consider a class of multicriteria stochastic optimization problems that feature risk- averse benchmarking constraints based on conditional value-at-risk and second- order stochastic dominance. We develop alternative mixed-integer programming formulations and solution methods for cut generation problems arising in optimization under such multivariate risk constraints. We give the complete linear description of two non-convex substructures appearing in these cut generation problems. We present computational results that show the effectiveness of our proposed models and methods.
