Due to the unpredictable nature of sudden onset disasters the humans are often caught with surprise so are the humanitarian relief organizations. In order to quickly react to the emergencies, supply chain networks are built instantly by the actors of the relief management. Parallel to this process, need assessment is started with the help of local experts which also confirm that the response cannot be lingered on due a delay in need assessment. After wards the supply chain structure needs to be changed once the right information is gathered by the passage of time. This is not all, actually the situation of the disaster prone area and people also changes by that time which always brings a challenging scenario for humanitarian relief actors to develop the supply chain design with flexibility.Primary focus of this paper is to define right supply chain designs for disaster response and post disaster phases in humanitarian relief.
