INTERACTIVE SIMULATION

IIncreasing computing power and continuously lowering costs of computing have resulted in greater attention to the field of interactive simulations. In interactive simulations, visual interfaces display the state of the simulated system and also allow an analyst to actively change the simulated system during execution. Interactive simulations are particularly suitable for large and semi-structured problems especially in which human interaction is an important consideration. Dr. Narayanan and his students at the interactive systems modeling and simulation laboratory in the industrial and human factors engineering program at Wright State University have integrated concepts/tools including object-based programming, model-view-controller paradigm, distributed computing, and web-based systems development to design, implement, and apply interactive modeling and simulation architectures for analysis of several complex dynamic systems, including problems in airbase logistics and discrete-part manufacturing.

HUMAN OPERATOR MODELING

As advances are made in computerization and automation, the role of humans in complex technological systems are shifting from primarily physical to cognitive problem solving and decision making tasks. This research theme is based on the premise that models and theories grounded in emerging work domains and operator activities are needed to support principled design. Using field studies, computational representations, and applications to domains such as logistics planning, manufacturing, and information search from large databases, Dr. Narayanan and his students have developed models of problem solving, decision making, troubleshooting, planning, and real-time control and applied it for design and implementation of human-centered decision support systems and user interfaces.
