Below is a partially completed aggregate production plan for Finestra Window Ornaments Co. There are currently 4 employees. Assume each worker produces 100 ornamental window coverings per month. The owner needs to build a feasible aggregate plan. Aggregated demand is 500 units in May, 540 units in June, 470 units in July, and 390 units in August. These numbers have been entered in the Forecast Sales row, in the table below. Worker production on regular time has also been added in the table below. Here are additional labor, inventory, and other production policies to assist in building an aggregate plan for Finestra. Cost per ornament produced on regular time = $80 each Cost per ornament produced on overtime = $120 each Cost per ornament if subcontracting is used: $150 each A maximum of 80 ornaments may be produced on overtime per month A maximum of 50 ornaments may be produced on subcontracting per month Inventory carrying cost: $50 per ornament in average inventory per month Backorders (stock outs) are not allowed.
