Test on Logistics and Supply Chain Management

Question 1: Do companies primarily aim to keep inventory levels low in order to guarantee the immediate availability of every single product at all times?

A. Ano

B. Ne

Explanation: The study materials describe 'lean production' as using 'small quantities avoiding any waste' and mention 'stockless production' as a name for pull strategies, indicating that low inventory aims to minimize waste and streamline production based on current demand. Conversely, push strategies, which often include 'safety stocks' to meet expected demand, are associated with ensuring availability and would typically involve higher inventory, not lower. The materials do not state that the primary goal for keeping inventory low is to guarantee immediate availability of every single product.

Question 2: According to the study materials, what is the primary reason push strategies often incorporate safety stocks?

A. To ensure production constantly reacts to actual consumption of components.

B. To satisfy current demand directly from a small inventory.

C. To mitigate risks arising from inaccurate demand forecasts.

D. To signal the need for replenishing components in bins.

Explanation: The study materials state: "Supplies are scheduled to meet expected demand, but because demand forecasts are not always accurate, push strategies often incorporate safety stocks and safety lead times." This directly indicates that safety stocks are used to manage the risk of inaccurate forecasts.

Question 3: Wal-Mart stores primarily receive their inventory directly from individual suppliers, rather than through a central distribution center.

A. Ano

B. Ne

Explanation: The study materials describe a 1.2-million-square-foot distribution center where thousands of different suppliers deliver their merchandise. This merchandise is then sorted and loaded onto Wal-Mart trucks to be rushed to particular Wal-Mart stores.

Question 4: The Wal-Mart supply chain system described in the passage automatically triggers a reorder to the supplier immediately after a product is scanned at the checkout.

A. Ano

B. Ne

Explanation: The moment a customer lifts a product off the shelf and it is scanned at checkout, a signal is generated and sent across the Wal-Mart network to the supplier. This signal prompts the supplier to make another of that item and ship it, restarting the entire supply cycle.

Question 5: According to the provided extract, what is the primary role of the main conveyor system, described as a 'Wal-Mart river,' within the Wal-Mart distribution center?

A. To continuously move products received from suppliers, read their bar codes, and then direct them to specific Wal-Mart stores for onward shipment.

B. To store a large volume of products temporarily until they are manually retrieved and sorted by staff.

C. To transport goods directly from manufacturers to customer homes, bypassing retail store locations entirely.

D. To generate reordering signals to suppliers as soon as a product is placed onto the conveyor belt.

Explanation: The extract describes the main conveyor system: 'the conveyor streams feed into a huge Wal-Mart river of boxed products. As the Wal-Mart river flows along, an electric eye reads the bar codes on each box... Electric arms from each stream reach out and guide the boxes – ordered by particular Wal-Mart stores – off the main river... into a waiting Wal-Mart truck.' This indicates its role in receiving, sorting by barcode, and directing products to specific stores for delivery.
