Abstract
directly onto a symbolic mathematical model, a qualitative model, and a numerical simulation model if necessary. An object-oriented programming environment can easily be built in terms of a collection of bond graph elements. These elements are then mapped directly into a qualitative equation and a symbolic mathematical equation. This capability results in a powerful approach to integrating various symbolic reasoning methods with standard numerical techniques. As there is a direct association between the bond graph element and the mathematical relationships, this knowledge representation scheme allows for a systematic approach to creating the models required for the symbolic reasoning mechanisms. For qualitative reasoning, each relation maps directly into a qualitative representation.
