摘　　要：为了增强虚拟环境中虚拟角色行为表现的多样性和变化性,从虚拟角色不确定性行为的相关概念入手,系统地研究了虚拟角色的不确定性行为及其建模的基本问题.指出并证明了个体与群体不确定性行为的关系,基于不确定性函数证明了虚拟角色不确定性行为建模的3种途径—不确定性决策、规划和动作建模,分析了不确定性行为建模的具体实现方法.最后基于坦克群对战仿真实验,说明了相关概念的合理性,验证了相关结论的正确性,实验表明,虚拟角色不确定性行为对仿真应用具有重要的影响.In order to improve the diversity and variability of behavioral representations of virtual characters in a virtual environment, we systematically studied associated modeling problems. Relationships between the uncertain behavior of individuals and of the colony were found and proven. Based on the definition of an uncertainty function, it was proven that we have three ways to set up mathematical models of uncertain behavior in virtual characters. These are： uncertain decision-making; planning; action modelling. Furthermore, the practical ways in which uncertain behaviors could be modeled were analyzed. Finally, in a battle simulation among tank groups, we proved the effectiveness of the concepts presented and validated the conclusion. Experiments were also carried out, showing that the uncertain behavior of virtual characters has important effects in applications using simulations.
