Transcribed Image Text:**Title: Aggregate Demand and Production Planning at Hill Enterprises**
**Introduction:**
Terri Hill, the president of Hill Enterprises, forecasts the firm's aggregate demand requirements over the forthcoming eight months. Her operations manager is evaluating a plan to meet this demand using a strategic workforce level adjustment, termed Plan A. This involves aligning production to the quantity demanded in the previous month, beginning with a standing inventory of 200 units.
**Demand Projection (Monthly):**
- **January:** 1,500 units
- **February:** 1,700 units
- **March:** 1,600 units
- **April:** 1,700 units
- **May:** 2,200 units
- **June:** 2,200 units
- **July:** 1,900 units
- **August:** 1,900 units
**Cost Metrics:**
- Inventory holding cost: $25/unit per month
- Stockout cost: $100/unit of lost sales
- Hiring cost: $50/worker
- Layoff cost: $80/worker
**Plan A:**
- Adjust the workforce to produce quantities aligned with the prior month’s demand.
- Deduct any incurred stockout, hiring, or layoff costs from the monthly budget.
**Planning Notes:**
Hiring and layoff expenses are accounted for in the same month in which changes occur. For instance, transitioning from a requirement of 1,600 units in January to 1,500 units in February incurs layoff costs for 100 units.
**Analysis Table:**
| Period | Month | Demand (units) | Production (units) | Hire (units) | Layoff (units) | Ending Inventory (units) | Stockouts (units) |
|--------|---------|----------------|--------------------|--------------|----------------|--------------------------|-------------------|
| 0 | December| 1,600 | 1,600 | | | 200 | |
| 1 | January | 1,500 | 1,600 | | | | |
| 2 | February| 1,700 | 1,500 | | | | |
| 3 | March | 1,600 | 1,700 | | | | |
| 4 | April | 1,700 |
