An expert system for security diagnosing of construction producing by CBR

For improving systematization degree and efficiency of security diagnosing for construction producing, the flow of security diagnosing for construction producing system by CBR is designed. By analyzing the security influence factors for construction production systemically, the case presentation technology for security diagnosing for construction producing is designed, and the case retrieval, case adaptation and case maintenance technologies are respectively studied. To test performance, random selection and case maintenance experiment modes are respectively designed, the system running result shows that under the second mode, average case retrieval ratio increases more and average case adaptation ratio decreases more with the increasing of case base scale. The obvious advantage of CBR is validated, the more the system is employed, the better performance it will appear.
