The expert system knowledge experession of computer generated air forces systems

摘要

in this computer generated air forces (CGAF) system,object oriented method is used to express expert knowledge.First of all,the entities functioning in the virtual basslefiedld environment needed to be modeled corresponding to the objects in real world,and expert knowledge was embedeed in entity model.Then,on the point of decision making,the expert knowledge expression feature and method were introduced in this paper.Therein,hierarchical knowledge expression method was convenient for sufficiently expert knolwedge expressing and rapid decision making;logical validation judge of decision rule base was the valid measure to make the rule set to meet sufficiency and uniqueness principle,and to make knowledge expressing simple and decision making rapidly .real effect of CGAF indicated that this expert knowledge method was valid to ensure the implement of system intelligent decision making ability sufficiently.
