In order to solve the problem that the current combat simulation Agent can not adapt to the complex battlefield environment and lack of dynamic planning ability,a multi-Agent intelligent development platform JACK based on BDI behavior model is found.Based on this platform,the armored infantry squad position attack combat simulation system is developed.The structure,function class and behavior algorithm of the Agent capability component of combat simulation are designed based on JACK Team platform.The individual soldier behavior model and team behavior model are constructed.The data exchange between JACK Team and Unity3D simulation environment is realized by Embedded models.The validity of the BDI model of JACK platform and good interaction with the open environment is verified by the system simulation data statistics.
