One of the most important tools for a systems engineer is their system model.
From this model, engineering decisions can be made without costly integration,
fabrication, or installations. Existing system modeling languages used to create
system models are detailed and comprehensive, but lack a true ability to unify
the system model by showing all relationships among all components in the
model. This paper shows by example how higraphs, a type of mathematical
graph, allow systems engineers to not only represent all required information in a
system model, but to formally show all relationships in the model through
hierarchies, edges, and orthogonalities. With a higraph system model, all
