Aiming at the problem that traditional operational command has been unable meeting the needs of combat, the paper established a basic carrier-based aircraft command and guidance workflow model. The whole process of attacking-ground guidance can be divided into several parts which can be build models using UML tool, under the thought of working flow theory. Because of the limits of the UML tools, Petri-net is used into these models to testify the validity and the rationality. Verification results show that the model can more quickly and accurately for battle command guidance system prototype development.
