Jill Nicholas believes there must be a better aggregate plan. She has suggested a hybrid plan, using a permanent workforce of 195 employees and subcontracting as needed. Once again, Jill has requested that you provide the following information:
(a) Calculate the regular-time production possible each period given a workforce of 195.
(b) Show what would happen if this plan were implemented.
(c) Calculate the costs associated with this plan.
(d) Evaluate the plan in terms of cost, customer service, operations, and humanresources.
