Abstract: As command and control(C2) systems become larger and more complex, architecture plays a more essential role during the whole life-cycle of the systems. Thereby, capability evaluation of C2 systems at architecture level becomes necessary and important for improving the system capability at the stage of architecture design. This paper proposes a method for information quality evaluation of C2 system at architecture level. First, the information quality model is proposed, including measures of information quality and methods of weights assignment and synthesis of the measures. Second, a framework for systematically conducting architecture-level information quality evaluation is provided. Finally, based on the framework, an experiment is conducted to validate the proposed information quality evaluation method. Experiment results show that the proposed method can effectively evaluate the information quality based on architecture models of C2 systems, which can help to identify key factors of impacting information quality and improve the system capability at the stage of architecture design of C2 system.
