Final Report :
EXECUTIVE SUMMARYThe
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.
