英文摘要
      In this paper, a reasoning method based on knowledge Petri nets and resolution rules is proposed. First, a knowledge base in the form of propositional logic is described as a knowledge Petri net. Second, a resolution structure is defined in a knowledge Petri net according to the input and output relationship of places and transitions. Third, a reasoning algorithm is presented to perform resolution operations by resolution structures. Further, a reasoning algorithm is given for an extended knowledge base. Finally, the Wumpus world problem is taken as an example to illustrate and verify the reasoning algorithm. It is proved that the reasoning method is sound and complete. The computational complexity involved in reasoning processes can be reduced by utilizing network structures of a knowledge Petri net.
