大型复杂系统是21世纪的核心技术之一，而军用复杂系统是各发达国家优先考虑的发展对象。在此背景下，简述了Agent的组成和原理，并对Agent用于军用复杂系统的建模过程进行了深入细致的分析，给出了复杂系统仿真模型和仿真结果，对仿真结果进行了分析。

First of all this paper introduces the composition and the principle of agent and makes thorough analysis of modeling process of military large-scale complex system, then presents the modeling and simulating result of the military large-scale complex system, and makes an analysis of the simulating result.
