Simplon Manufacturing must decide on the processes to use to produce 1650 units. If machine 1 is used, its production will be between 300 and 1500 units. Machine 2 and/or machine 3 can be used only if machine l's production is at least 1000 units. Machine 4 can be used with no restrictions. Machine 1 Fixed cost 500 800 200 50 Variable cost 2.00 0.50 3.00 5.00 Minimum Production 300 500 100 any Maximum Production 1500 1200 800 any 3 4 (HINT: Use an additional 0 - 1 variable to indicate when machines 2 and 3 can be used.)
