Application of hierarchical modeling concepts to a multi-analysis environment

An environment which enables the application of multiple analysis formalisms or paradigms to a commonly defined problem is extended to include hierarchical modeling concepts. A description of the development of the object-oriented environment is provided as background. Concepts of model development are introduced in order to emphasize the value of hierarchical modeling concepts. Implementation of these concepts in the environment is then discussed. The implementation of experimental frame concepts, in which system behavior represented in the model is separated from behavior related to experimentation, is explored. Hierarchical concepts are then applied to the pairing of a model with an experimental frame in order to address future simulation goals such as hybrid and multilevel simulation.<
