◆ Plan A: Production at a fixed rate (equal to minimum requirements) of 1,000 units per month and subcontracting additional units.
◆ Plan B: Vary labor, to produce previous month's demand. The company produced 1,300 units in June. The cost of hiring additional workers is IDR 45,000,000 per 100 units produced. The layoff cost is IDR 90,000,000 per 100 units cut.
◆ Plan C: Maintain current workforce at a production rate of 1,300 units per month. Subcontract the rest to meet demand. Assume that the remaining 300 units from June are available in July.
◆ Plan D: Maintain current workforce at a level capable of producing 1,300 units per month. Allow a maximum of 20% overtime (from production level per month) with a premium of IDR 600,000 per unit. Any additional requirements are subcontracted.
