Stochastic discrete resource allocation problems are difficult to solve. In
this paper, we propose a new algorithm designed specifically to tackle the
m. The algorithm combines with the Nested Partitions method, the Ordinal Op
timization techniques, and an efficient simulation control technique. The r
esulting hybrid algorithm retains the global perspective of the Nested Part
itions method and the fast convergence properties of the Ordinal Optimizati
on. Numerical results demonstrate that the hybrid algorithm can be effectiv
ely used for many large-scale stochastic discrete optimization problems.
