A manufacturing firm uses a level utilization production-planning horizon of three months.They have developed a forecast for the coming three quarters that appears in the table.They can add no more than 10% of their production capacity as overtime and can order no more than 10% of a month's regular capacity via subcontractors.The company has a zero backorder policy but has space for a maximum of 100 items in their finished-goods inventory.If all extra costs are shown in the table,what is the minimum cost sales and operations plan?
