The application relates to the technical field of
computer simulation, and discloses a military
simulation scenario description method based on a
knowledge graph, which comprises the following steps: acquiring command message data and
electromagnetic environment link state data, and dividing a command session set according to message header identification; constructing a multi-layer associated
knowledge graph comprising a
session layer, a
sentence layer and a
traceability layer; according to the
electromagnetic environment link state data, the cumulative link connection duration is counted, and when a preset threshold is met, a
scenario grounding operation is triggered, and an execution element layer is generated in the graph; the graph element scale change amplitude before and after each grounding operation is counted, and a session
traceability inflation index is generated through weighted
processing; finally, a complexity identification node carrying the index is established and written into the graph, and the final
knowledge graph file, the replayable command message sequence and the
simulation executable scene
package are output. The application can quantify the structural inflation risk caused by the environment and the protocol mechanism in the description stage, and is suitable for large-scale
simulation interoperation.
