Chapter 13, Problem 7P
Consuelo Chua, Inc., is a disk drive manufacturer in need of an aggregate plan for July through December. The company has gathered the following data:
*No costs are incurred for unmet demand, but unmet demand (backorders) must be handled in the following period. If half or more of a worker is needed, round up.
**Note that there is no holding cost for June.
What will each of the two following strategies cost?
a) Vary the workforce so that production meets demand. Chua had eight workers on board in June.
b) Vary overtime only and use a constant workforce of eight.

The costing information that is used to evaluate the total cost of each plan is as follows:• Inventory carrying cost: $4 per unit per month• Subcontracting cost per unit: $15 per unit• Working hours: 8 hours per day• Average pay rate: $12 per hour ($96 per day per worker)• Labour-hours to produce a unit: 2 hours per unit• Cost of increasing daily production rate (hiring and training): $300 per unit• Cost of decreasing daily production rate (layoffs): $700 per unitUse these information to formulate an aggregate plan. The firm would like to use level strategy: constant workforce for the aggregate planning. The firm chooses the average demand of the…
