Abstract: This paper presents an efficient exact solution procedure for a general stochastic hub location problem with single allocation, incorporating uncertainties in origin–destination flows, transportation costs, and hub capacities. A scenario-based model is used to minimize the expected overall costs, requiring two decisions: (i) the location of hubs, which remains fixed across all scenarios; and (ii) the allocation of each origin/destination to one of these hubs in each scenario.
