ERP (Enterprise Resource Planning) information system has been widely applied in business for its powerful features and is seen as essential in integration management. From the perspective of resource integration, the logistics operation of immediate disaster relief and reconstructions in the aftermath do have something in common to that of business operations. However, little research has been done in applying the ERP concept to the resource management of humanitarian relief of natural disasters. Streams of unsolicited and inappropriate supplies often flow into the disaster areas and clog the ports and warehouses, or even become obstacles to the aid agencies in making the supply of much-needed goods more difficult. This paper aims to introduce the ERP concept into the strategic planning and logistics operation procedure for disaster relief. The case of Typhoon Morak (2009) which caused widespread flooding in Southern Taiwan is simulated to the ERP Workflow system of Data Systems Consulting Co. This paper strives to urge the attention to build an ERP System for Disaster Relief Management so as to promote the integration of relief resources by balancing supply-demand sides and improving the efficiency of relief operations.
