Te krytyka Role of Human Operators in Closed Loop Systems

Automation does neeliminate thee need for human judgment; it shifts thee nature of that judgment. In a closed loop environment, operators move from direct manual control to superiory roles. They monitor trends, analyze event logs, andd make decisions about setpoint changes, tuning parameters, and system reconfiguration.

Training bridges thee gap between system compledity and d operator capability.
