Abstract: Joint operations plan generation, both domestic and international practices predominantly adhere to two models: the“rapid revision of plan”approach grounded in pre-existing plans, and the“slow plan-making”method rooted in operational procedures and combat rules. However, the process of plan making is often encumbered by disorganized combat information management, a complex information exchange process, and cognitive biases among personnel, collectively leading to protracted planning cycles that fall short of meeting the exigencies of actual combat scenarios. Consequently, framework for intelligent generation of joint operations plans based on KG+LLM is proposed. The period of plan making is shortened by knowledge graphs and large models technologies. Furthermore, the “Antonov Airport Blitzkrieg”scenario is integrated to design a human-machine collaborative“intelligent drafting”model based on KG+LLM. The feasibility and viability of this framework have been demonstrated through its application in the CMO sea-air wargaming system.
