Based on Capability of C4ISR Architectural Modeling and Analysis
C4ISR system is complex system. Such systems architecture and complex needs of many. Then complex system’s capability requirements are difficult to catch. Description of capability requirements are usually imprecise and do not support architecture analysis. The paper uses an extended UML modeling technique to analyzing the requirements of C4ISR capabilities. It also introduces a new model convert domain model into the Description Logic ontology. Use Description Logic ontology description the standard DoD Architecture Framework, the proposed method may populate C4ISR architectural analysis.
