• The theory should provide an open-ended set of abstraction methods (e.g., aggregation and omission) and characterize their applicability. The theory should characterize, and provide a means to estimate, the simulational complexity of a model (typically, abstractions are intended to reduce such complexity).


The theory should provide the elements of manipulation for more encompassing theories such as those of systems engineering, design, and management. 2
