Abstract: The strategy of solving problems in carburizing expert system is studied in this paper. In order to advoid subjective view and one-sidedness,multiblackboard strategy of solving problems is proposed, which are problem blackboard, domain blackboard, argument blackboard and conclusion blackboard.The problems of no generally-acknowledge are multiple experts.Tnis paper builds a theoretical framework of argument on the basis of propositional knowledge,and the argument algorithms is designed. The results of the experiment are satisfactory.

Key words: expert system, blackboard structure, carburizing
