In order to grasp the overall perspective of joint fire planning system, the concept of systems engineering can be applied to the system analysis on joint fire planning. Analyzing from the dimensions of time, logic and profession, it can be divided into 3 relevant stages from the preparation of joint fire planning to the end of the battle, and then each stage of the time dimension can be divided into 4 logical steps, and by using various professional knowledge to complete various stages and steps. The results show that stylization of the fire planning command can be achieved and the command efficiency can be enhanced comprehensively by this method.
