Answer 2

Decision variables in a linear programming model are controllable. So option 2 is the correct answer.

• Decision variables are the unknown quantities that are estimated as an output of the LPP solution.
• Function of decision variable: All linear programming problems aim to either minimise or maximise some numerical value representing cost, profit, quantity of production etc.
• The decision variable is a quantity that a decision maker can control.
• For example, in a hospital for labour scheduling, the number of nurses to employ during that shift in an emergency room may be a decision variable.
• Decision variables are unknowns of a mathematical programming model.
• We can typically determine their optimum values with an optimisation method.
