What are automatic systems that can make decisions referred to as?

Automatic systems that can make decisions are referred to as logic systems. These systems utilize logical operations to process input data, evaluate conditions, and produce outputs based on predetermined rules or algorithms. In the context of refrigeration and similar fields, logic systems are essential for automation, allowing processes to run efficiently, respond to various inputs, and ensure the system operates within desired parameters.

Logic systems can be programmed to adapt based on varying conditions, which is critical for applications where precision and responsiveness are required. These might include controlling temperature regulation in refrigeration systems or managing operational alerts based on system performance.

In contrast, the other options are not directly associated with the ability to make decisions autonomously. Open loop systems operate without feedback and do not adjust their operation based on the output, making them less flexible. Annunciation systems are primarily designed to provide alerts and warnings rather than make decisions. Indicating systems focus on displaying information rather than processing inputs to make decisions. Therefore, the term that accurately describes automatic decision-making systems is logic systems.
