Which term refers to simulations run entirely without human intervention?

The term that refers to simulations run entirely without human intervention is "Closed Simulations." In this context, closed simulations are designed to operate autonomously, meaning that they rely on predefined parameters and algorithms without the need for real-time human decision-making or input. This allows for the exploration of various scenarios and outcomes without the complexities and variability introduced by human operators.

Closed simulations are particularly valuable in situations where consistent and repeatable results are necessary, such as in training environments or in testing theoretical models. They enable researchers and practitioners to analyze data and refine models based on the simulation outcomes, all while maintaining control over the entire process without external influence. Such a setup can be useful in military operations, engineering, and other fields where precision and consistency are crucial.

In contrast, the other terms mentioned relate to different types of simulations. For example, "Live Constructions" may involve real-life elements, "Semiautomated Forces" includes some level of human oversight, and "Real-World Simulations" incorporate real-life scenarios that may require human interaction. Thus, the specificity of "Closed Simulations" accurately aligns with the descriptor of being fully autonomous.
