What is another term for decision variable?

The term "decision variable" is often categorized under "controllable input." This is because decision variables are the elements within a linear programming model that decision-makers can control or manipulate to achieve the best possible outcome. They represent choices that can be made, such as quantities to produce, resources to allocate, or investments to undertake.

By understanding that decision variables are controllable, one can appreciate how they enable decision-makers to explore various scenarios and optimize their objectives based on resource constraints and desired outcomes. Other terms like "uncontrollable input" denote factors that cannot be changed or influenced, while "feasible solution" refers to a potential solution that satisfies all constraints rather than the variables that can be adjusted. "Decision alternative" may imply options but does not specifically highlight the nature of variables that can be controlled in a mathematical model.
