Abstract： In the aviation field，the reuse rate of process design knowledge for parts with long cycles and complex processes was low，and there was a lack of effective knowledge recommendation and inheritance.The current methods for process knowledge generalization mainly focused on using fuzzy knowledge and reasoning algorithms to overcome the dependence of process methods on the environment. These methods did not significantly help in addressing the incompleteness and inconsistency of formalized expressions. This paper was based on the standardized expression of process data，the knowledge graph construction and heuristic search for process recommendations were carried out，resulting in a higher knowledge reuse rate， which provided a way of thinking for the high-reusability，high-eficiency，and knowledge-driven process planning of parts with long cycles and complex processes.

Key words： process knowledge generalization； process planning； standardized expression of process data;knowledge graph；heuristic search
