Q. Jack is concerned about his company's corporate image and has decided against using
hires and fires. Instead, he has asked you to consider a chase aggregate plan using the current
workforce supplemented by either overtime or undertime to change capacity to match
demand exactly. He has asked for the following information from you:
(a) How many production hours would be required each period to produce the exact quantity
needed?
(b) How many regular-time production hours are available each period?
(c) How many overtime production hours would be needed each period?
(d) Show what would happen if this plan were implemented.
(e) Calculate the costs associated with this plan.
(f) Evaluate the plan in terms of cost, customer service, operations, and human resources.
(g) Compare this chase strategy with level strategy and conclude which is better.
