Systems Engineering focuses on the design of a system, and Cybernetics focuses on understanding communication and control in designed and natural systems. In Systems Engineering, views of a system are typically represented in SysML in terms of Requirements, Structure, Behavior, and Parametrics. By supporting the analysis of constraints on subsystem properties, parametrics capture whether or not a system design “works”. Cybernetics measures the difference between current state and desired goal by accounting for information returning the system – “feedback” – and for the system's corrective action as it steers towards its goal. This paper shows how (1) cybernetic concepts can help focus a SysML modeling effort on critical questions, and (2) cybernetic characteristics of systems can be modeled in SysML.
