Information overload is a core problem that both complex military and civilian organizations referred to as Cyber-Physical and Social Systems (CPSS) are facing today. Executives or commanders want better ways to communicate complex insights so they can quickly absorb the meaning of the data and act on it. In recent literature, this problem has been referenced as BigData and data deluge. BigDatadata deluge are contextual to CPSS complex dynamic environments. Addressing the Big Data 4Vs (volume, veracity, variety and velocity) requires that Fusion of Information and Analytics Technologies (FIAT) be integrated. Integration is proposed here via a FIAT computational model to provide analysis (analytics) and synthesis (fusion) support to decision-makers in order to make sense (measuring, organizing, understanding and reasoning) of the data-information-knowledge hierarchy present in numerous domains of application.
