| Abstract: | Taking into account the complexity of aeronautical structure, an integrated knowledge representation model applicable to four stages of finite element modeling is presented. Based on it, the resultant process solution models featured by logic reasoning and algorithm based task planning at each stage are specified, which fall into the framework of blackboard mechanism. Through various application examples, the proposed approach proves to be effective and practical. |
