Jill has decided that the BackPack Company must have very good customer service. She has asked you to develop a level aggregate plan using inventories but not back orders. All demand must be met each period. You must: (a) Calculate the aggregate production rate. (b) Calculate the appropriate workforce given the aggregate production rate. (c) Show what would happen if this plan were implemented. (d) Calculate the costs of this plan. (e) Evaluate the plan in terms of cost, customer service, operations, and human resources.
