Abstract: For simulation deduction applications, a multi-granularity spatio-temporal representation model of operational plan is designed from a perspective of spatio-temporal modeling, Providing technical support for command and control systems. Firstly, the operational plan is abstractly expressed as a set of entities and event sequences. Then, the spatio-temporal analysis and design of the multi-granularity spatio-temporal representation model are implemented for the deduced entities and deduced events respectively. Finally, an experimental analysis is conducted with the simulation deduction of U.S. Army anti-carrier mosaic warfare, and the feasibility of the method is verified.
