Abstract:Aiming at the problem that the quantitative analysis of preemptive or postemptive operational thinking in the military field is not comprehensive and thorough, this paper uses Lanchester equation to carry out theoretical analysis, establishes 2 models of preemptive and postemptive, and gives the general conditions that the application model needs to meet. The simulation results show that the model can provide some help for military training and command decision-making.
