Planning humanitarian and relief supply chains in crisis situation is fought of operational and tactical challenges such as uncertainty in injured people demands and magnitude of the crisis, lack of reliable information, destroying of connection links, and so on. This paper proposes a new two-stage multi-period stochastic blood supply chain network model to help the flow of blood supply to solve the demands of injured people and emergency hospitals. In this model, blood units and its derivatives considered for the first time in the literature simultaneously and application of the model tests with real data of likely earthquake in Tehran mega city (Densest city of Iran). Proposed network consists of three layers including the donated areas, the collection blood centers and the transfusion blood center, which is usually a governmental organization. In order to solve the proposed two-stage stochastic model L-shaped algorithm, an efficient algorithm to solve scenario based stochastic models, has been used.
