Iran is among the ten disaster-prone countries and, in terms of earthquake, it has been ranked the sixth in the world. Although the damages caused by the disasters are not irreversible from different aspects, they could be reduced to minimum by choosing appropriate preventive actions as well as preparedness plans to counteract the impacts of these incidents. According to the increasing trend of disasters and crises which destroy businesses and communities, considering relief supply chain under crisis situations (HDRSC), in the wide field of supply chain management (SCM), is necessary and vital. Even though considerable volume of research have been done in the field of supply chain and with the focus on the disaster relief, few studies have addressed its complex features and properties. So, this paper concentrates on the activities such as demand determination and supply chain coordination. This research provides the supply chain managers who are faced with similar problems in other environments with valuable insights.
