SysML (Computer science), System design, Sociotechnical systems


In modern design of complex systems, there is lack of consideration of social elements in Socio-Technical Systems. The Human Mental Model is a vital part of multidisciplinary system design, and can contribute to the potential for system failure when not considered during the design phase. This thesis will examine the Systems Modeling Language (SysML) viewpoints and views to determine whether they illustrate elements of human mental models, and increase communication between individuals holding different perspectives. Two models were created in SysML, the first comparing SysML to mental model graphs, and the second was the Lynx X-ray Observatory, a project in concept development at NASA. This research discovered viewpoints and views relate favorably with aspects of mental model. It was also found that illustrating Lynx viewpoints and views was a valuable aid in eliciting concerns and desires of stakeholders, leading to a project more in line with desires of the stakeholders.
