1. What is the primary purpose of analytics modeling?
A. To eliminate all uncertainty
B. To represent real-world systems mathematically or
computationally
C. To guarantee perfect predictions
D. To replace all business decisions
Correct Answer: B. To represent real-world systems
mathematically or computationally.
Rationale: Analytics models simplify real-world systems so that
relationships, predictions, decisions, or optimization problems
can be studied systematically.
2. Which type of model is primarily concerned with finding the
best possible decision?
A. Descriptive model
B. Predictive model
C. Optimization model
D. Classification model
Correct Answer: C. Optimization model.
,Rationale: Optimization models identify decision-variable
values that maximize or minimize an objective while satisfying
constraints.
3. In a linear programming model, what does the objective
function represent?
A. A restriction on variables
B. The quantity being maximized or minimized
C. A random variable
D. The feasible region only
Correct Answer: B. The quantity being maximized or minimized.
Rationale: The objective function expresses the goal of the
optimization problem, such as maximizing profit or minimizing
cost.
4. Which of the following is a decision variable?
A. Total profit already calculated
B. Number of products to manufacture
C. Historical sales data
D. A fixed production cost
Correct Answer: B. Number of products to manufacture.
Rationale: Decision variables are quantities whose values are
selected by the optimization model.
,5. What is a constraint in an optimization model?
A. The desired outcome
B. A mathematical restriction on decisions
C. The model's prediction
D. A random observation
Correct Answer: B. A mathematical restriction on decisions.
Rationale: Constraints limit feasible decisions because of
resources, capacity, regulations, or other requirements.
6. What does the feasible region contain?
A. All theoretically possible solutions
B. Only solutions satisfying all constraints
C. Only optimal solutions
D. Only infeasible solutions
Correct Answer: B. Only solutions satisfying all constraints.
Rationale: The feasible region consists of all decision
combinations that satisfy every constraint.
7. In linear programming, the optimal solution is generally
found at:
A. Any random point
B. A corner/extreme point of the feasible region
, C. The midpoint of the feasible region
D. An infeasible point
Correct Answer: B. A corner/extreme point of the feasible
region.
Rationale: For a linear objective and linear constraints, an
optimum, when one exists, occurs at an extreme point.
8. What does an infeasible optimization problem mean?
A. It has infinitely many optimal solutions
B. No solution satisfies all constraints
C. The objective function is linear
D. The solution is always zero
Correct Answer: B. No solution satisfies all constraints.
Rationale: Infeasibility occurs when the constraints are
mutually incompatible.
9. What is a binding constraint?
A. A constraint that has unused capacity
B. A constraint satisfied with equality at the solution
C. A constraint that is ignored
D. A constraint containing no variables
Correct Answer: B. A constraint satisfied with equality at the
solution.
