Hetero-Functional Graph Theory for Interdependent Smart City Infrastructures
Development in the smart city literature has predominantly focused on device connectivity & control, data acquisition, and governance structures. Though these topics are both complex and valuable, smart cities are much more comprehensive. Infrastructure systems enable smart cities by providing critical services such as electric power, natural gas, potable water, wastewater treatment, and transportation. These infrastructures, however, do not operate in a vacuum, as the literature converges from individual smart infrastructure systems to an interdependent smart city infrastructure system. Methodological tools for design and analysis of such interdependent systems have been lacking. Some have used graph theoretic approaches, which neglect the distinct functionality of these systems. Others have used Model-Based Systems Engineering techniques, but those don’t lend themselves to quantitative analysis. Hetero-functional Graph Theory has been developed over the last decade and most recently it has specifically been applied to interdependent smart city infrastructures.
In this tutorial on Hetero-functional Graph Theory, We first guide participants systematically through the fundamentals of model-based systems engineering and graph theory, using smart cities as examples. Thereafter, the tutorial continues by providing the conceptual foundations of Hetero-functional Graph Theory, building on the discussion of MBSE and Graph Theory. The tutorial concludes with a demonstration of Hetero-functional Graph Theory on a smart city infrastructure test case. The test case demonstrates the use of hetero-functional graph theory to model an interdependent infrastructure system consisting of a water distribution system, an electric power system, and an electrified transportation system.[/collapse] [collapse title=”SPEAKERS” active=”true”]
