Final Report :EXECUTIVE SUMMARY
The PROGNOS Knowledge Exchange Module (KEM) team has been tasked by the George Mason University, Department of System Engineering and Operational Research, C4I, to provide a system engineering approach to integrate FORCEnet’s Command and Control (C2) and Intelligence Surveillance and Reconnaissance (ISR) systems to the predictive naval situation awareness system, PROGNOS. FORCEnet is future Navy implementation of Network Centric Warfare, comprised of many Navy C2 and ISR systems and systems of systems. PROGNOS is designed to bridge “stovepiped” systems from data interchange to knowledge interchange and is divided into five different modules: Reasoning, Knowledge Storage, Knowledge Management, Knowledge Exchange, and Simulation. The team will focus on the PROGNOS Knowledge Exchange module which will be the primary interface to external systems.
Due to the quantity and complexity of the systems that PROGNOS is required to interoperate with, the team narrowed down our external systems to two: the Distributed Command Ground System – Navy (DCGS-N) and the Net Enabled Command Capability (NECC) system. The DCGS-N is the fleet variant of the Department of Defense (DoD) DCGS Family of Systems that provides integration of ISR support capabilities previously accessed from a variety of stand-alone systems. The NECC system, formerly known as the Global Command and Control Family of Systems, is the next generation DoD C2 system. Global Command and Control System-Maritime’s (GCCS-M) objective is to satisfy Fleet C4I requirements through the rapid and efficient development and fielding of C4I capabilt.
Using the Vee System Engineering model, a common and widely used system engineering approach, the team has developed a System Requirements Document (SRD) that captures the sponsor’s originating requirements and the team’s derived functional, interface, and performance requirements. The team has also developed SysML architecture diagrams that depict some DODAF operation and system views. We have developed requirements and architecture which fed into the System Requirements Document (SRD) and the Interface Control Document (ICD). The ICD describes the systems that the Knowledge Exchange Module must interface with and defines the interfaces. To verify and validate the requirements and the KEM, we provided a detailed scenario walkthrough for architecture verification and validation and a simulation that translates simulated DCGS-N XML message to PROGNOS ontology to verify key XML related requirements and validate the DCGS-N interface approach.The KEM team’s scenario and simulation only provides a limited verification and validation. To fully integrate PROGNOS with FORCEnet, the system Vee approach has to be applied many times for other external systems with different standards and formats. The PROGNOS team suggests that the Department of System Engineering and Operation Research continue our work and further define other types of external system interfaces by repeating our approach.
