Non-Topological Model - a model that represents elements of a system, device or process without representing the relationships between those elements. Although easier to develop than topological models, non-topological models (when used for diagnostic applications) force the Analyst to model test coverage explicitly. Non-topological models are sometimes used to model "black box" devices, when engineering details are not available. Like topological models, non-topological models are not diagnostic models in and of themselves, since they contain no information about tests. Compare with structural model, topological model, diagnostic model.
