- . ( ) W W W Q W Q III questions 25 thru 26 reference the following linear programming formulation 27. What is the correct equation for computing the Interest on 1-year investments is 5%, interest on 2-year expected value of perfect information (EVPI)? investments is 11%, and interest on 3-year investments III is 17% a. EVPI = expected value under risk for best Deposit alternative - expected value under certainty. $10,000 b. EVPI = expected value under certainty - Year 1 expected value under risk for best alternative. C. EVPI = expected value with sample information X 12 - expected value without sample information. d. EVPI = expected value without sample Year 2 X13 information - expected value with sample Withdrawal information. $5,000 X 23 X14 e. none of the above Year 3 1 X24 28. In a linear optimization model the variables X, Y, Withdrawal X3 and Z are binary. Which of the following would be the [X] constraint(s) required to ensure that two and only two of Year 4 these variables are positive? a. 2X + 2Y + 22 53 b . X + Y + 2=2 25. What is the objective function? X s 2, and Y S 2, and Z S 2 a. Maximize X4 d. X+Y+Zs3 b. Maximize X4 + $5,000 e. None of the above c. Maximize X14 + X24 + X34 + $5,000 29. One possible objective function in an investment d. Minimize X12 + X13 + X14 over time problem e. None of the above Is to minimize the deposits b. Is to maximize the deposits 26. What is the constraint at year 3? . Is to minimize the withdrawals a. X13 + X23 = X34 + $5,000 d. Is to maximize the number of investments b. 1.05X13 + 1.11X23 - 1.17X34 = 10,000 . None of the above c. 0.11X13 + 0.05X23 - X34 = 5,000 d. 1.11X13 + 1.05X23 - X34 = 5,000 30. An unbounded solution must have at least one variable that can go to e. None of the above infinity b. must be constrained C. must have its solution become more optimal as a decision variable goes to infinity d. is not possible with more than 2 variables e. None of the above
