Textbook Question
Chapter 9, Problem 14P
Consider again the kitty litter ordering policy for Sam’s Cat Hotel in Problem 13.
- Suppose that the weekly demand
forecast of 90 bags is incorrect and actual demand averages only 60 bags per week. How much higher will total costs be, owing to the distorted EOQ caused by this forecast error? - Suppose that actual demand is 60 bags but that ordering costs are cut to only $6 by using the Internet to automate order placing. However, the buyer does not tell anyone, and the EOQ is not adjusted to reflect this reduction in S. How much higher will total costs be, compared to what they could be if the EOQ were adjusted?
