Concept explainers
The president of Hill Enterprises, Terri Hill, projects the firm’s aggregate demand requirements over the next 8 months as follows:
Her operations manager is considering a new plan, which begins in January with 200 units on hand. Stockout cost of lost sales is $100 per unit. Inventory holding cost is $20 per unit per month. Ignore any idle-time costs. The plan is called plan A.
Plan A: Vary the workforce level to execute a strategy that produces the quantity demanded in the prior month. The December demand and rate of production are both 1,600 units per month. The cost of hiring additional workers is $5,000 per 100 units. The cost of laying off workers is $7,500 per 100 units. Evaluate this plan.
Note: Both hiring and layoff costs are incurred in the month of the change. For example, going from 1,600 in January to 1,400 in February incurs a cost of layoff for 200 units in February.

- A barbershop has been using a level workforce of barbers five days per week, Tuesday through Saturday. The barbers have considerable idle time on Tuesday through Friday, with certain peak periods during the lunch hours and after 4 p.m. each day. On Friday afternoon and all day Saturday, all the barbers are very busy, with customers waiting a substantial amount of time and some customers being turned away. What options should this barbershop consider for aggregate planning? Howwould you analyze these options? What data should be collected, and how should the options be compared?arrow_forwardA barbershop has been using a level workforce of barbers five days per week, Tuesday through Saturday.

The operations manager is going to use a new plan, which begins in January with 200 units on hand and ends with zero inventory in August. Assume, Inventory holding cost is $20 per unit per month and stockout cost of lost sales is $100 per unit. The plan is called plan A. Compute the cost of plan A. Plan A: Vary the workforce level to execute a “chase” strategy by producing the quantity demanded in the prior month. The December demand and rate of production are both 1,600 units per month. The cost of hiring additional workers is $5,000 per 100 units. The cost of laying off workers is $7,500 per 100 units. Evaluate this plan.arrow_forward
- WSS company makes weatherproof surveillance systems for parking lots. Demand estimates for the next four quarters are 25, 9, 13, and 17 units. Prepare an aggregate plan that uses inventory, regular time and overtime and back orders. Subcontracting is not allowed. Regular time capacity is 15 units for quarters 1 and 2, 18 units for quarters 3 and 4. Overtime capacity is 3 units per quarter. Regular time cost is $2000 per unit, while overtime cost is $3000 per unit. Back order cost is $300 per unit per quarter; inventory holding cost is $100 per unit per quarter. Beginning inventory is zero. Questions At the end of quarter 3, what is the ending inventory of finished systems? Answer: No ending Inventory =0 What is the total cost? 15*2000 + 6*2300 +4*2600 + 9*2000 + 13*2000 + 17*2000 =$132, 200 What is the average cost per unit?

- evelop a production plan and calculate the annual cost for a firm whose demand forecast is fall, 9,700; winter, 8,000; spring, 7,000; summer, 11,700. Inventory at the beginning of fall is 485 units. At the beginning of fall you currently have 35 workers, but you plan to hire temporary workers at the beginning of summer and lay them off at the end of summer. In addition, you have negotiated with the union an option to use the regular workforce on overtime during winter or spring only if overtime is necessary to prevent stockouts at the end of those quarters. Overtime is not available during the fall. Relevant costs are hiring, $80 for each temp; layoff, $160 for each worker laid off; inventory holding, $5 per unit-quarter; backorder, $10 per unit; straight time, $5 per hour; overtime, $8 per hour. Assume that the productivity is 0.5 unit per worker hour, with eight hours per day and 60 days per season.

In January, the company produces 15,000 windows and ended the month with 9,000 windows in inventory. EZ-Windows' management team would like to develop a production schedule for the next three months. A smooth production schedule is obviously desirable because it maintains the current workforce and provides a similar month-to-month operation. However, given the sales forecasts, the productioncapacities, and the storage capabilities as shown in Table 2, the management team does not think a smooth production schedule with the same production quantity each month possible.The company's cost accounting department estimates that increasing production by one window from one month to the next will increase total costs by $1.00 for each unit increase in the production level. In addition, decreasing production by one unit from one month to the next will increase total costs by $0.65 for each unit decrease in the…arrow_forward
