Decision Support System of Bridge Risk Based on CBR

According to the basic principle of case-based reasoning (CBR), the bridge risk decision support system was presented in this research. Firstly, the various risk factors in every stage of the bridge construction were analyzed in a multi-level way. Specially, the ones in the operation stage were decomposed in detail. Consequently, the operation process of the bridge risk decision support system was introduced in a general way, and the method of case representation, case retrieval and case preservation were elaborated in detail. Finally, an example was given to illustrate the effectiveness of the proposed approach. The result shows that, as one of the new reasoning methods of artificial intelligence, The techniques of CBR can provide the reference for the bridge risk decision research.
