Intelligent form selection system for large span structures

The intelligent design theory of structural form selection is applied in large span structures. A prototype system of intelligent choice of structural form for large span structures is developed. Microsoft Access 2000 for Windows is used as a foreground developing tool for building case base system, Microsoft Visual C + + 6.0 for Windows as a developing tool for scheme generation, and the Expert System Development tool C-ADVISOR 3.0 as a developing tool for scheme evaluation and decision-making. The system includes three sub-systems: case base system (CBS), scheme generation system (SGS), and scheme evaluation system (SES) and scheme decision-making system (SDS). CBS is built on the techniques of object-oriented programming, SGS on the Case Reasoning and data mining, and SES and SDS on fuzzy inference and fuzzy multiple-attribute decision-making.
