Abstract

AbstractHuman beings are integral to today's complex systems of systems. Human behaviour, interactions, abilities, complexity, and limitations will have a dramatic effect on the successful realization of system capabilities. Therefore the human factors considerations need to be evaluated in conjunction with the overall systems engineering. Systems engineers need to address them upfront and throughout the system life cycle resulting in effective Human Systems Integration (HSI). Systems engineers are increasingly using Model Based System Engineering (MBSE) techniques to define systems requirements, behaviour, structure, interactions, etc. Typical architecture notations are the Systems Modeling Language (SysML) for modelling systems and the Unified Modeling Language (UML) Profile for DoDAF and MODAF (UPDM). The metamodels defining these notations contain implicit, but not explicit elements for defining how the human fits into the architecture. The Unified Architecture Framework (UAF) has standardized a set of Human Views (called Personnel Views in UAF) into its system of systems framework, allowing the Human aspects to be considered in conjunctions with the rest of the architecture. The UAF Personnel views will not be standalone, but like SysML will allow users to interface with specialty to analyse human aspects in both quantitative and qualitative ways. It is only by taking this integrated approach that systems can be fit for purpose by including the human impact and contribution to overall system performance. This paper will describe these views and how they fit into the overall architecture as well as how they can interact with a spectrum of human factors and architecture tools.
