Study of Situation Assessment Method Based on Plan Recognition Theory
基于计划识别的态势估计方法研究

For the shortage of plan recognition method presented by Kautz(1987) in controlling mechanism, a plan recognition method based on planning knowledge graph is discussed in detail. Using first-order predicate logic as formal language, an instance of tactical intelligent planning is analyzed and a situation assessment model combined tactical intelligent planning system and a tactical plan recognition system are proposed. The plan library, which is dynamic set up, could break through the limit of closed world hypothesis in Kautz's plan recognition method. The model is capable of supplying reasonable hypothesis for enemy's action goal and plan and projecting enemy's future action, which is helpful to command decision.
