SACON

SACON eases structural analysis by suggesting specific analysis strategies. The system uses knowledge about stresses and deflections of the structure under different load conditions to determine the appropriate strategy. SACON is designed to identify the type of numerical analysis, the needed modeling detail, and specific analysis data required. Decisions are constructed on the basis of material behavior,relations between geometry and structural behavior, measures of the importance of time and temperature changes, and user-supplied specifics such as characteristics of the spectrum of analysis types, the relation between accuracy and model detail on the structure, its mechanical loadings, and its temperature states. The system is rule based, employs backward chaining, and was implemented using EMYCIN. The system was developed at Standford University. (1977-1978)
