PLEASE DO NOT JUST COPY THE EXISTING ANSWER!

A parts supplier has a contract with a manufacturer to supply 1550 units of component C for the next 6 months. The demand from the manufacturer is given below.

Month (t)	Demand (Dt)
1	100
2	200
3	300
4	400
5	300
6	250

The supplier has 20 workers and 50 units of C on hand now. Each worker can produce 10 units of C per month. The company can recruit from the local labor market, but the recruits must be trained for 1 month before they can be used in production. Each worker can train at most five recruits during a month. A worker is paid $3000 per month, when used in production or training. Firing, or laying off, a worker costs $5000. Each recruit is paid $1500 during training.

Production ahead of schedule incurs an inventory holding cost of $50 per unit per month. Each unit of C not delivered on schedule involves a penalty cost of $75 per month until delivery is completed. All deliveries must be completed in 6 months. The supplier requires a labor force of 30 workers and 50 units of C at the end of the 6th month.
