Abstract: Aiming at the lack of supporting data, description specifications and auxiliary tools in the process of combat scene design, this paper proposes a combat scene design method based on knowledge graph. By using combat scene as the core conception when constructing the knowledge graph model, this method can more efficiently and concisely describe the relationship between various elements in the process of combat scene design, so as to lay a foundation for solving the problem of data silos in the military field. This work has theoretical significance for optimizing the engineering design of combat scene.
