Quality Control Expert System of Pump Concrete Based onTechnology of Data Mining XIA Hong-xia, ZHAO Jing-jing, CAO Bin, WANG Lei,ZHONG Luo(School of Computer Science and Technology, Wuhan University of Technology. Wuhan 430070, China)This paper introduced the whole process that how to apply the technology of data mining into the design of the system of Pump Concrete Expert System. Owing to the problems existing in the technologies and the environment of construction, the application of data mining was imperative under the situation. Firstly the technology of data mining was analyzed and then the statistic analysis and decision trees were used successfully in the system based of the actual requirement. The model of data mining and the whole framework founded on the quality control were provided at the same time. The system was triumphantly applied into the factual production, which was worth mentioning.quality control; data mining; statistic analysis; decision trees
