Project management exercise questions Lecturer: Q17-3) Your company has asked you to determine the financial risks of manufacturing 6, 000 units of a product rather than purchasing them from a vendor at $66. 50 per unit. The production line will handle exactly 6, 000 units and requires a one-time setup cost of $50, 000. The production cost is $60/unit. Your manufacturing personnel inform you that some of the units may be defective, as shown below:
% defective 0 1 2 3 4
probability of occurrence (%) 40 30 20 6 4
Defective items must be removed and replaced at the cost of $145/defective unit. However, 100 percent of units purchased from vendors are defect-free. Construct a payoff table, and using the expected-value model, determine the financial risk and whether the make or buy option is best.
Units purchased= 6000
Cost per unit=$66. 50
Set up cost=$50000
6000*66. 50+6000*60+50000= 809000

= 6000*60= 360000 = 6000*60= 360000 = 6000*60= 360000 = 6000*60= 360000 = 6000*60= 360000
Total Cost = 410000 418700 427400 436100 444800
Expected Cost of manufacturing = 410000*0. 4+418700*0. 3+427400*0. 2 +436100*0. 06 +444800*0. 04
= 419048
Expected cost of manufacturing = 41*0. 4+418700*0. 3+427400*0. 2= 419048
The total cost of manufacturing is $419048, but if the firm buys from a vendor, the total cost would be $809000. The firm should therefore manufacture instead of purchasing the product from vendors. In manufacturing, the firm will be able to save $389952.
