Question

Haley Photocopying purchases paper from an out-of-state vendor. Average weekly demand for paper is

180

cartons per week for which Haley pays

$30

per carton. Inbound shipments from the vendor average

950

cartons with an average lead time of

5

weeks. Haley operates 52 weeks per year; it carries a

6

-week

supply of inventory as safety stock and no anticipation inventory. The vendor has recently announced that they will be building a facility near Haley Photocopying that will reduce lead time to

four

weeks

.

Further, they will be able to reduce shipments to

200

cartons. Haley believes that they will be able to reduce safety stock to a

4

-week

The changes decrease Haley's average aggregate inventory level by how many cartons AND HOW MUCH VALUE?

Explanation / Answer

Average aggregate inventory level can be defined as :

Average aggregate inventory level

= Cycle inventory ( ie the order quantity) / 2 + Safety stock

In the first case, aggregate inventory level

= Order quantity /2 + Average weekly demand x Number of weeks of supply inventory

= 950/2 + 180 x 6

= 475 + 1080

= 1555

In the second case, aggregate inventory level

= Order quantity / 2 + annual weekly demand x Number of weeks of supply inventory

= 200 / 2 + 180 x 4

= 100 + 720

= 820

Decrease in Haley’s average inventory level = 1555 – 820 = 735

Decrease in Haley’s average inventory level by value = $30 / carton x 735 cartons = $22050

DECREASE IN HALEY’S AVERAGE INVENTORY LEVEL = 735

DECREASE IN HALEY’S AVERAGE INVENTORY LEVEL BY VALUE = $22050

DECREASE IN HALEY’S AVERAGE INVENTORY LEVEL = 735

DECREASE IN HALEY’S AVERAGE INVENTORY LEVEL BY VALUE = $22050
