Abstract:The design of Distributed Mineral Processing Expert System (DMPES) based on Internet/Intranet was explored under slack coupling with Agent-oriented Programming (AOP) method and Multi-agent distributed cooperating solution pattern. Inhomogeneous agents were proposed，that is，agents may be built on WAN，LAN and single CPU by tense coupling mode，and solution agents need interoperation of heterogeneous software agents based on symbol system， neural network，gentic algorithm for backgroundanalytical applications. All agent communication is performed through message passing and blackboard mechanism. Message passing includes synchronous communication method and asynchronous communication method. Cooperative mechanism includes negotiatory mechanism and dividual mechanism. Based on Distributed Component Object Model (DCOM) technology，building frame class by C++，it accelerates the execution of Agent. It makes knowledge transferred among Agents easy，and brings up communicating efficiency greatly.
Key words: multi agent; communication mechanism; negotiatory cooperation; dividual cooperation; distributed component object model; framework class
