AN INTEGRATED SYSTEM FOR CONCURRENT DESIGN AND ANALYSIS IN CONCEPTUALAEROSPACE DESIGN

This paper describes a knowledge-based system to support concurrent de sign and analysis. The system, DESSIA (DEsign Support System for Integ rated Analysis) provides designers with information to analyze a probl em and obtain design outputs by using the expertise accumulated in the system. The system Combines a knowledge base, engineering database, a nd program library in an object-oriented expert shell. The system is f lexible and evolutional. Programs and data can be registered, maintain ed, and developed with little labor, thereby providing a systematic fr amework for constructing and developing hierarchical databases of prog rams and data for concurrent design and analysis.
