摘　　要：探索了基于Internet/Intranet松耦合环境设计分布式选矿专家系统DMPES ,采用面向Agent的系统开发方法和Multi agent分布协作求解模式。基于DCOM技术 ,以C ++构建框架类加速了Agent的实现。文中提及的智能主体的通信机制、协同求解中的领域问题描述、协商及分布式协作机制的建立思想对复杂问题求解提供了支持。DMPES系统在网络环境下基于WindowsNT WorkStation采用C ++开发实现 ,这里描述的协作机制已在该系统中获得应用 ,运行结果表明其具有较好的性能。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, genetic algorithm for background analytical 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.
