大坝安全监测专家系统的总体设计

Overall design of dam safety monitoring expert system

建筑物安全监测专家系统属大型的实用复杂系统．从系统组成、系统结 构到知识表示、推理机制等都提出了很高的要求．结合具体工程项目，研制开 发了大坝安全监测专家系统ＤＳＭＥＳ．给出了ＤＳＭＥＳ的总体构成及实现策 略、各部分的技术措施等．包括恰当的知识表示及不确定性推理方法、综合推 理机、外部数据库技术、支撑软件库、图形库、定性推理与定量分析之间的接 口设计等．

As a kind of large complex ES for practical use, hydraulic structure safety monitoring expert system puts much more requirements on considerations for from system composition and system structure to knowledge representation and inference engine. As a real engineering project, the Dam Safety Monitoring Expert System (DSMES) is developed by the author. This paper describes the overall construction of DSMES, its implimentation strategy and some technical considerations. Included are proper knowledge representation methods,inexact inference model, synthetic inference engine, external database technique, software base, graph base and interface between logical inference and numerical analysis.
