question

True

answer

True or False: In the quantity discount model, it is possible to have a cost-minimizing solution where annual ordering costs do not equal annual carrying costs.

question

D) ABC analysis is based on the presumption that controlling the few most important items produces the vast majority of inventory savings E) Criteria other than annual dollar volume, such as high holding cost or delivery problems, can determine item classification in ABC analysis

question

answer

answer

question

A) Effective control of all goods leaving the facility is one applicable technique

answer

Which of the following statements regarding control of service inventories is TRUE? A) Effective control of all goods leaving the facility is one applicable technique B) Service inventory needs no safety stock, because there's no such thing as a service stockout C) Service inventory has carrying costs but not setup costs D) Good personnel selection, training, and discipline are easy E) Service inventory is a fictional concept, because services are intangible

question

True

answer

True or False: The fixed-period inventory model can have a stockout during the review period as well as during the lead time, which is why fixed-period systems require more safety stock than fixed-quantity systems.

question

False

answer

True or False: Safety stock in inventory systems depends only on the average demand during the lead time.
