Green III b,1 a Robins School of Business, University of Richmond, Richmond, VA 23173, USA b School of Continuing Studies, University of Richmond, Richmond, VA 23173, USA Received 17 December 2003; accepted 25 May 2005 Available online 16 August 2005 Abstract Disasters are large intractable problems that test the ability of communities and nations to effectively protect their populations and infrastructure, to reduce both human and property loss, and to rapidly recover. The seeming random- ness of impacts and problems and uniqueness of incidents demand dynamic, real-time, effective and cost efficient solu- tions, thus making the topic very suitable for OR/MS research. While social sciences and humanities literatures enjoy an abundance of articles on disaster management, the OR/MS community is yet to produce a critical mass. In this paper, we survey the literature to identify potential research directions in disaster operations, discuss relevant issues, and pro- vide a starting point for interested researchers.
