Homework answers / question archive / the following linear program: Min 8X + 12Y S
the following linear program: Min 8X + 12Y S.L. IX + 3Y 2 9 2X + 2Y = 10 6X + 2Y = 18 X,Y 20 a. Use the graphical solution procedure to find the optimal solution. b. Assume that the objective function coefficient for X changes from 8 to 6. Does the optimal solution change? Use the graphical solution procedure to find the new opti- mal solution. c. Assume that the objective function coefficient for X remains 8, but the objective func- tion coefficient for Y changes from 12 to 6. Does the optimal solution change? Use the graphical solution procedure to find the new optimal solution. d. The sensitivity report for the linear program in part (a) provides the following objec- tive coefficient range information: Variable Objective Coefficient 8.000 12.000 Allowable Increase 4.000 12.000 Allowable Decrease 4.000 4.000 ? Y How would this objective coefficient range information help you answer parts (b) and (c) prior to resolving the problem?
