Abstract
Abstract The instant invention is a system performance simulator which includes a library of expression-literate model artifacts, each of which is at least partially representative, mathematically and operatively, of a model element which includes at least one virtual interface point suitable for operative association with another such point. Assembly means are operatively and disconnectably communicative with the library for accessing selected model artifacts and is capable of understanding the representative expression-literacies characterizing the artifacts, for establishing operative associations between interface points of the artifacts to establish an organized assembly of such artifacts. Means are also provided which are operatively communicative with the assembly means for conducting a performance simulation of such an assembly.
