CBR based expert system for house repair after earthquake

To improve practical efficiency and theory feasibility of house repair or reinforce measures so as to reduce life and property loss as could as possible after large scale earthquake, the two stage CBR implement mode is proposed to realize expert system for house repair or reinforce after earthquake. The first stage CBR system is employed to make out house repair strategies, and the second stage CBR systems is employed to make out house repair detail steps and instruction after earthquake. Thus, both the reasoning reaction velocity and the precision are ensured. In both stage CBR systems, four key technologies including case presentation, case retrieval, case adaptation and case maintenance are studied respectively. The system running result shows that, comparing with the conventional single state CBR system, both average case retrieved ratio and average case satisfactory degree by the two stage CBR system are obviously improved. The two stage CBR system is suitable for solving complex and multi disposing problems such as house repair after earthquake.
