Research On Modeling Of C~4ISR Architecture Based On UML

Architecture design is an important content of top level design and key element to ensure integration, interoperation between C~4ISR systems and realization of the efficient integrative C~4ISR systems. Therefore, to study the C~4ISR architecture design is of great theoretical and practical significance.The research of C~4ISR architecture needs to be under the guidance of the scientific methods and take the architecture description norm as its main basis. With the C~4ISR architecture norms DoDAF, this does research in the C~4ISR system architecture modeling based on UML.Focused on the C~4ISR system architecture framework DoDAF, the thesis introduces its modeling method and discusses its deficiencies and the existing problems. Then a UML-based architecture modeling method is provided, which is about that how to use UML develop DoDAF standard compliant architecture models from three levels - the view, the visualization of products and the precise definition and constraints of the data model. It not only provides a good visual representation of the symbol, but also makes the data model be strictly defined with UML semi-formal semantics. So it has some practical value on the development of C~4ISR systems. The thesis also provides a UML-based C~4ISR architecture development process, and discusses the design process of the products using UML and the validating method of the models.Finally, a brigade-level air defense scenario is provided. Using the modeling methods and development process as described above, the thesis provides some architecture product models, so as to test the practical method.
