Study of Situation Assessment Method Based on Plan Recognition Theory

摘要: 針對Kautz(1987)計(jì)劃識(shí)別方法在控制機(jī)制上的不足，討論了基于規(guī)劃知識(shí)圖的計(jì)劃識(shí)別方法；以一階謂詞邏輯為形式語言，研究了戰(zhàn)術(shù)智能規(guī)劃的一個(gè)實(shí)例，給出了一種集成了戰(zhàn)術(shù)智能規(guī)劃系統(tǒng)和戰(zhàn)術(shù)計(jì)劃識(shí)別系統(tǒng)的態(tài)勢估計(jì)模型。該模型通過動(dòng)態(tài)建立計(jì)劃庫突破了Kautz計(jì)劃識(shí)別方法中封閉世界假設(shè)的限制，可以對敵軍的行動(dòng)目標(biāo)和行動(dòng)計(jì)劃提出合理的假設(shè)，并在此基礎(chǔ)上預(yù)測敵軍的未來行為，為指揮決策提供依據(jù)。Abstract: 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 Kautzs plan recognition method. The model is capable of supplying reasonable hypothesis for enemys action goal and plan and projecting enemys future action, which is helpful to command decision.
