Structural and Landscape Analysis for the Robust Capacitated International Sourcing Problem (RoCIS)

In this paper the robust capacitated international sourcing problem (RoCIS) is approached. It consists of selecting a subset of suppliers with finite capacity, from an available set of potential suppliers internationally located. This problem was introduced by Gonzalez-Velarde and Laguna in 2004(1), where they propose a deterministic solution based on Tabu Search memory strategies. In this work a structural and landscape analysis for the larger problem instances is reported, to try of explain the relative hardness observed when the improved tabu solution (11) is applied to solve the instances.
