中文摘要：

利用目标编群思想描述多agent行动之间的协作关系，建立了一种基于多agent计划识别的战术态势估计模型。分析了计划库的构成及结构层次，给出了一种基于多agent假设的计划识别算法。以一阶谓词逻辑为形式语言，扩展了战术智能规划的一个实例，引入了描述多agent完成同一任务的谓词和算子。对实例的分析说明了基于多agent计划识别的态势估计过程，表明了使用该方法求解态势估计问题的可行性。

英文摘要：

To describe the cooperation relations among the actions of multi agent in the situation assessment system, the paper utilizes the idea of target classification to set up a tactical situation assessment model based on the multi agent plan recognition method. The components and structure hierarchy of the plan library are analyzed and a plan recognition algorithm based on multi-agent hypotheses is proposed. Using the first-order predicate logic as formal language,an instance of tactical intelligent planning is extended and some predicates and operators for expressing the multi agent tasks are introduced. The instance is analyzed in detail to explain the situation assessment process based on multi-agent plan recognition, which shows the feasibility of using the presented method for solving the problem of situation assessment.
