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.
