Abstract: In large complex systems such as national infrastructure and defense systems, the human component may account for more than half of the life cycle cost of the system. Model-based approaches for analyzing requirements, developing designs, prototyping systems, and testing and evaluating new systems are essential to necessarily incorporating people. The emergent properties of large complex systems will NOT behave according to established physical laws and this must be included in systems cognitive networks that are largely unknown and certainly uncontrolled. Without a comprehensive research effort based on simulation of the emerging network, it is not possible to predict how the system will behave — only that it will be capable of entering dynamical regimes that are not now known. These observations are examples of the kinds of insights that may arise from research in the fundamentals of human-system integration; particularly with respect to cognitive/decision-making systems. We will discuss the inherent complexity of even simply systems and their potential impact on the systems engineering community and efforts to develop and apply MBSE to any large-scale system acquisition enterprise.
Steve Harris is a former Navy Medical Service Corps officer who has conducted research and managed programs in human performance and human factors engineering for the Navy, DoD, NASA, Dept. of Energy, and others in his 40+ year career. He was head of Manned Flight Simulation at the Navy’s aircraft test center at Patuxent River. He was the Chief Military Scientist at the Navy’s Center for Applied Research in Artificial Intelligence. He has published research on system architectures for radar and sensor data fusion. He worked on Space Shuttle and X-38 crew systems for NASA in Houston. He worked on very large computer simulations of complex systems at Los Alamos National Laboratory. More recently he was Deputy Director of the Network Dynamics and Simulation Science laboratory at Virginia Tech. He helped Federal Railroad Administration develop requirements for a railroad locomotive cab simulator. He has worked on pipeline, transportation and Smart Grid SCADA systems. He is now working on a project to develop symbology standards for FAA’s NextGen systems. As he says, apparently he can’t keep a job.
Jennifer McGovern Narkevicius, PhD is CEO/Managing Director of Jenius LLC. Her clients have included the US Air Force, US Navy, and the US Federal Railroad Administration. Jen works in Human Factors and Human Systems Integration to bring human requirements to defining systems requirements including applications from high performance military aviation; civil aviation; highway, rail and web based enterprise applications. She has developed standards and policies as well as programs ranging from Air Traffic Management, Automated Systems, Collaborative Knowledge, and Distributed Decision Making, to development of research facilities and agenda for future work. She is the current Co-Chair of the INCOSE Human Systems Integration Working Group and Events Committee Finance Chair.
