Resumen
This paper introduces a holistic framework, underpinned by Category Theory, for the process of conceptual modeling of complex engineered systems, generically representing the models as graph data structures, rendering stakeholder-informing views like matrices and visual graphs from the graph data structure, and reasoning about the visualized information in order to refine and enhance the concept of the system. This iterative process?a composition of a cognitive segment with a computational segment?proves to be an important formulation of the model-based systems architecting cycle.
