Abstract: A multi-experts knowledge processing system is presented in this paper. The system is mainly composed of five modules which are knowledge representation, knowledge acquisition, knowledge organization, problem-solving and arbitration system. The system is composed of three blackboards which are problem blackboard, argument blackboard and conclusion blackboard. Each knowledge source (ks) may solve the problems shown on the problem blackboard, or put its views, or argue with other KSs on the argument blackboard. The conclusion blackboard can record the final conclusion.
