A comparison of decision-maker perspectives for optimal cholesterol treatment
IBM JOURNAL OF RESEARCH AND DEVELOPMENT, 56(5).

Optimal Allocation of Surgery Blocks to Operating Rooms Under Uncertainty
OPERATIONS RESEARCH, 58(4), 802–816.
TL;DR:
A fast and easy-to-implement heuristic works fairly well, on average, across many instances, and the robust method performs approximately as well as the heuristic, is much faster than solving the stochastic recourse model, and has the benefit of limiting the worst-case outcome of the recourse problem.
