Supervisory control is a research area that focuses on developing control strategies for complex systems where human operators are involved in making high-level decisions. This field aims to design control systems that allow operators to supervise and/or interact with automated processes in order to achieve optimal system performance. Supervisory control research often involves studying human-machine interaction, decision-making processes, and the development of algorithms and techniques to support operators in managing and controlling complex systems. This area of research is particularly relevant in fields such as manufacturing, transportation, and process automation.
