# Purse Company produces a line of purses

Chapter 13

1. The Purse Company produces a line of purses. The manager, Sally Smith, is interested in using a level aggregate plan. Inventories and backorders will be used to handle demand fluctuations. She has asked you to develop such a plan.
 Use the following data to solve the first seven problems. Problem Data Cost data Regular-time labor cost per hour \$17.00 Overtime labor cost per hour \$21.00 Subcontracting cost per unit (labor only) \$80.00 Holding cost per unit per period \$13.00 Back-order cost per unit per period \$20.00 Hiring cost per employee \$550.00 Firing cost per employee \$400.00 Capacity data Beginning workforce 300 employees Beginning inventory 600 units Labor standard per unit 8 hours Regular time available per period 200 hours Overtime available per period 35 hours Subcontracting maximum per period 1200 units Subcontracting minimum per period 600 units Demand data Period 1 6000 units Period 2 5000 units Period 3 8000 units Period 4 6000 units Period 5 7000 units Period 6 5000 units
1. Calculate the aggregate production rate.
2. Calculate the appropriate workforce given the aggregate production rate. If Sally will need to hire workers, include this.
3. Show what would happen if this plan were implemented.
4. Evaluate the plan in terms of cost, customer service, operations, and human resources.
1. Sally has decided that the Purse Company must have very good customer service. She has asked you to develop a level aggregate plan using inventories but not backorders. All demands must be met each period. You must:
1. Calculate the aggregate production rate.
2. Calculate the appropriate workforce given the aggregate production rate.
3. Show what would happen if this plan were implemented.
4. Calculate the costs of this plan.
5. Evaluate the plan in terms of cost, customer service, operations, and human resources.
