Constraints in Word Problems

A sheet company produces standard and luxury sheets. Retail 80 and 145 respectively. Cost of materials 25 and 45 respectively.

Three production depts:

10 cutters

150 machinists

40 packers

The factory works 37.5 hr weeks.

Labor is as follows for standard and luxury respectively:

Cutting 0.25 and 0.375 w/charge per hour 40

Machining 2.50 and 6.25 w/charge per hour 8

Packing 1.25 and 1.25 w/charge per hour 12

How do I find the constraints?

Any assistance is greatly appreciated as this is greek to me.

Thanks!
