This article presents a general model for effect-based multinational and interagency operations coordination by means of a Computer Aided Dispatch (CAD) tool. The focus is on the analysis of this model as integration based on CAD technology between incident, emergency, and crisis management C4ISR systems in order to be used in effect-based multinational/interagency operations with heavy military forces participation. A CAD-based C4 model for incident/emergency/crisis management requires a lot of tests before industry/field implementation owing to its complexity. This is the reason why the presented work considers the role of computer simulation experiments in driving this change, using the general process of Concept Development and Experimentation (CDE) used in NATO.
