The Department of Homeland Security (DHS) is funding the development of a Critical Infrastructure Protection Decision Support System (CIP DSS) that is intended to be used by DHS decision makers to assess the impacts of deliberate attacks or disruptions on the United States’ infrastructures and how they might be mitigated by investments in protective or recovery technologies.  One of the 17 critical infrastructures is the “Defense Industrial Base.”  The basic mechanisms of such a model are the flows, especially surge response flows, of war materiel from private sector defense industries to the Department of Defense (DoD).  In order to capture surge flows, additional models of military logistics, especially deployment, and military missions are needed to drive the behavior of interest.  Basic system dynamics models are being considered to provide this feedback to the basic mechanisms.  With this consideration of military mission effectiveness, the models main output decision metric is an estimation of casualties, which presents its own system dynamics modeling challenges.
