Chapter 11, Problem 13P
Summary Introduction
To determine: The total cost of the plan using subcontract with no overtime.
Introduction: The aggregate plan is the output of sales and operations planning. The major concern of aggregate planning is the production time and quantity for the intermediate future. Aggregate planning would encompass a time prospect of approximately 3 to 18 periods.

Although the BackPack Company has always used a levelaggregate plan, Jill is interested in evaluating chase aggregateplans also. She has asked you to calculate how many hires and fi reswould be necessary to adjust capacity to meet demand exactlyeach period. If necessary, incur some undertime. Calculate thenumber of workers needed each period.
suppose that the demand for personal computers increased each month, as follows: Month Demand Month Demand January 410 April 620 February 320 May 430 March 500 June 380 In addition to the regular production capacity of 300 units per month, PM Computer Services can also produce an additional 200 computers per month by using overtime. Overtime production adds 20% to the cost of a personal computer. Determine a production schedule for PM that will minimize total cost.

- Plan production for a four-month period: February through May. For February and March, you should produce to exact demand forecast. For April and May, you should use overtime and inventory with a stable workforce; stable means that the number of workers needed for March will be held constant through May. However, government constraints put a maximum of 5,000 hours of overtime labor per month in April and May (zero overtime in February and March). If demand exceeds supply, then backorders occur. There are 100 workers on January 31. You are given the following demand forecast: February, 90,000; March 65,000; April 110,000; May, 55,000. Productivity is four units per worker hour, eight hours per day, 20 days per month. Assume zero inventory on February 1. Costs are hiring, $50 per new worker; layoff, $70 per worker laid off; inventory holding, $10 per unit-month; straight-time labor, $10 per hour; overtime, $15 per hour; backorder, $20 per unit a.
