Abstract : The objective of this study is to explore the technical feasibility and issues involved in a broad cooperative effort to develop a knowledge-based expert system (KBES) environment for finite element modeling and analysis assistance. The environment is intended to serve the dual requirements of providing specialization capabilities to individual organizations so that they can 'customize' the KBES to reflect their own expertise and generalization capabilities to serve as a 'community memory' of the discipline. This report presents an architecture for such an environment. The key elements of the architecture are: a hierarchial, multiple-views representation of the spatial and functional characteristics of structural systems; an explicit representation and manipulation of modeling assumptions which allows fine-grained control over model synthesis; and an evolutionary model development strategy whereby modeling decisions can be methodically modified or retracted after an analysis iteration to generate more appropriate models. Keywords: Artificial intelligence; Mathematical models.
