用计算机试验获取知识以建立加速器故障诊断原型专家系统

USING COMPUTER TESTING TO ACQUIRE KNOWLEDGE IN BUILDINGTHE PROTOTYPE OF HEFEI SYNCHROTRON DLAGNOSIS EXPERT SYSTEM

开发的合肥同步辐射加速器故障诊断专家系统（ＨＳＤＥＳ）原型为产生式系统，由人机界面、时序分析器、知识库、“黑板”、推理机、解释子系统和知识获取子系统构成。该原型系统在过去３年已用来处理加速器调试、运行期间记录的与真空有关的故障数据。该原型系统知识库中的部分故障知识是借助于蒙特卡罗模拟、用计算机试验代替物理实验获得的──目前，这些知识从专家和书本都无法获得。

The developed prototype of Hefei Synchrotron Diagnosis Expert System (HSDES) is aproduction system and roushly speaking consists of an interface,a time series analysis subsystem,aknowledge base,a blackboard, an inference engine, an explanation subeystem and a knowledgeacquisition subsystem.The prototype of HSDES has ben uscd to deal with the data on malfunctionsconcerning vacuum recorded during try operating the synchrotron in the past three years.Someknowledge on malfunctions in the knowledge basee of the prototype, which can not be found from bothdomain experts and books, has been acquired and refined from those data obtained by computer testingwith the help of Monte Carlo simulation instead of physics experiment.
