Abstract

This work presents a single-allocation hub location problem with uncertainty that aects the amount of product sent between origins and destinations, thetransportation costs and the capacities of the hubs. This uncertainty is modelledby a set of dierent scenarios occurring with a given probability only after thehubs are selected. In order to minimize the expected overall costs of the system,two decisions have to be made: (i) the location of the hubs (this location doesnot change in the scenarios), and (ii) the allocation of each origin/destinationto one of these hubs. A mixed integer programming formulation and some validinequalities are provided for the introduced problem.
