The aim of this paper is modeling the critical products' supply chain to supply suffering population by strong earthquakes and tsunamis. The supply chain of these products is described through the use of Supply Chain Operations Reference (SCOR) model using a set of standard processes. The developed model allows minimization of companies' complexity in the chain and identifies which are the critical links, obtaining an integral vision of the chain. It is concluded that the proposed model will contribute the improvement of delivering critical products to affected people.
