Stochastically constrained problems also remain relatively unstudied, in particular in domain
focused articles. A nal promising area for research is robust simulation optimization.
Realizing the limitations of the Taguchi method, new robust sim-opt techniques have been
recently developed, but most of them have been tested only in theoretical settings thus far.
Applying these new techniques to more practical problems, and comparing their performance,
is an interesting area for additional research.
