What term describes automatic systems capable of making decisions?

The term that best describes automatic systems capable of making decisions is "logic systems." Logic systems are designed to process inputs and produce outputs based on a set of predetermined rules or conditions. They utilize Boolean logic to determine the appropriate response without human intervention, allowing for automated decision-making in various applications.

In contrast, annunciation systems are primarily used for alerting operators to certain conditions or alarms but do not make decisions themselves. Indicating systems provide information about the state of a process or system, helping users track performance but lacking the capability for decision-making. Open loop systems operate without feedback; they execute commands based on input without adjusting for results, which further differentiates them from logic systems that are designed to adapt and make informed decisions based on real-time data.
