Abstract: The research on operational concept is a key to the design of intelligent wars in the future, and operational concept modeling applies language, symbols, tables, graphs, etc. to abstract and simplify the description of operational concept (imagined real war systems) which can provide a bridge for communication with experts in various fields. Firstly, the connotations, system framework and development and the other relevant contents of operational concept are sorted out and summarized, model-based system engineering and conceptual modeling are analyzed, and the connotations of operational concept modeling is described. Then, the characteristics and principles of operational concept modeling are induced, its modeling process is established. Finally, the advantages and disadvantages of relevant modeling languages and methods and their applications in operational concept modeling are discussed and summarized. The comprehensive integration method of operational concept modeling is established, it is expected to provide reference for future operational concept and its modeling.
