Priority should be given in the order mentioned below.
1. Maintain maximum capacity output even though demand is lower for the period because demand for the next period is higher and inventory holding costs are only $1 per unit per period.
2. Over time output for remaining demand, including demand for the following year, since it is less costly than subcontract production and inventory keeping costs are just $1 per unit per period.
3. There is no obligation for output to be subcontracted.
