面向土建工程的专家系统建造工具C-ADVISOR及其应用

The Tool——C-ADVISO——for Building Expert Systems in Civil Engineering Design Aids

本文介绍了一个面向土建工程设计的专家系统建造工具—C—ADVISOR.该系统采用分级知识获取策略,通过知识获取模块与问题求解模块之间的信息反馈,实现了动态知识获取.在解决冲突问题上,采用了模糊决策方法,使问题的解决更为合理.系统集定性推理与定量计算于一身,从而能够满足建造设计型决策专家系统的需要.系统还应用预制文本法和执行追踪法对推理过程进行解释,使系统具有良好的透明性.在C—ADVISOR 系统的支持下,建造了“抗震结构最优设防水平决策专家系统”,并在IBM—PC/AT 机上实现,运行效果良好.

The article introduces a tool,C-ADVISOR for building expert systems in civilengineering design aids.With graded tactics of knowledge acquisition,we realize thedynamic knowledge acquisition through the feedback of information between theknowledge acquisition module and problem-solving module.In solving the clashedproblems.we use the fuzzy-decision method,and thus the problem can be solvedmore reasonably.The system puts together the qualitative reasoning and quantita-tive calculating,therefore,it can satisfy the need for decision expert system of con-struction-design.The system also explains the reasoning process with the methodof pre-written version and the tracing method.As a result,the system has goodtransparence.Under the support of C-ADVISOR system,we have set up the Deci-sion Expert System of Best Fortified Level for Anti-Seismic Structure and operatedon IBM-PC/AT.The results are satisfactory.
