基于多层模糊Petri网的编队空战战术决策

Tactical Decision-Making for Formation Air Combat Based on Hierarchical Fuzzy Petri Net

对于编队空战战术决策这一个动态的不确定性决策问题,FPN是一种快速、适用、直观的方法,但存在不能适应知识库的扩展和更新,以及不能利用结构化方法对知识库进行建模的问题。为此,根据编队空战战术决策过程,利用抽象库所和抽象变迁来提高模型对复杂知识的表示能力,建立基于HFPN的编队空战战术决策模型。以典型的"二对一"空战战术为例建立决策规则库,经过抽象库所和抽象变迁的逐步精细化,并用模块合并方法和"补弧"对模型进行简化,建立"二对一"空战战术决策的精细化FHPN模型。通过算例验证表明,基于HFPN的建模方法用于编队战术决策不仅发挥了模糊Petri网基于知识的表达和逻辑推理能力,而且降低了编队空战战术决策的复杂性。

Tactical decision-making for the formation air combat is a dynamic decision-making process with uncertainty,and the Fuzzy Petri Net（FPN） is a fast,practical and intuitionistic method for it.However,FPN is not adaptable to extension,updating and modeling of knowledge base.In order to apply structure theory to knowledge base analysis and modeling by utilization of Abstract place and Abstract transition conveniently,Hierarchical Fuzzy Petri Net（HFPN） was used for modeling in tactical decision-making for the formation air combat.The knowledge base of tactical decision-making of the 2∶ 1 formation air combat was built up,which were then refined through the Abstract place and Abstract transition.Model reduction method and complementary operations were introduced to simplify the reasoning,and a refined HFPN model for the 2∶ 1 tactical decision-making of the formation air combat was established.Finally,the advantages of HFPN was validated by the results of example in the 2∶ 1 tactical decision-making for the formation air combat,which showed that the HFPN based modeling can not only has the expression and reasoning ability of Petri net,but also reduce the complexity of the reasoning.
