Question
What-if analysis:A) may involve changes in the objective function coefficients.B) requires that only one parameter change while the rest are held fixed.C) may involve changes in the right-hand side values.D) All of the choices are correct.E) None of the choices is correct.
Solution
D) All of the choices are correct.
Explanation: "What-if analysis" in the context of decision-making or problem-solving often involves adjusting various parameters to see how those changes could affect the outcome.
A) It may involve changes in the objective function coefficients. This is because the objective function defines the goal of the model, and changing its coefficients will change the model's predictions.
B) It requires that only one parameter change while the rest are held fixed. This is a common approach in what-if analysis, known as sensitivity analysis. It allows for understanding the impact of one variable at a time, keeping others constant.
C) It may involve changes in the right-hand side values. In the context of constraints in optimization problems, changing the right-hand side values will alter the feasible region and potentially the optimal solution.
Therefore, all the choices A, B, and C are correct aspects of what-if analysis.
