Abstract: Safety evaluation index is a fundamental and key element in composing hydraulic metal structure healthy diagnostic model, however,the determination of weighting of Indexes is closely related to the reasonability and reliability of the whole evaluation result.Based on the safety level, importance and expertise of the main factors on hydraulic metal structure,we also combine integration of AHP method of nine marks and expert evaluation method to determine the weight coefficient of each index, the comprehensive health diagnosis of gates and hoists based on AHP method are first constructed in line with scientific and rational principles .And we use the model to achieve the specific project safety evaluation of hydraulic metal structures, also comparing it with the traditional comparative analysis, proving the comprehensive health diagnosis based on AHP model to be a more scientific, reasonable and reliable one.

Abstract: Combining the successful applications in AI, in this paper, an expert system is studied and designed for evaluating the safety of hydraulic metal structures, whose goal is compute the reliability of hydraulic metal structures. Applying the techniques of AI, a framework is made up for evaluating the safety of hydraulic metal structures. The framework of knowledge base system is designed and presented with the domain knowledge. Based on the theory of relational database, the conceptual and logical views of database system are designed and analysed. Additionally, method base system is designed. A practical example is given to illustrate the process of using this system. This system has features of practical and advanced and expand.
