Abstract: | Each are (i, j) of the network has capacity

where
ij
is a non-negative random variable. The capacity of any arc may be reduced increased by an amountu

wherev is the expected maximum flow. This problem is formulated as a two-stage linear program under uncertainty. Each feasible
generates a constraint
where
is the probability arc (i, j) is in the minimum cut set and
the expected value of the maximum flow under
