Question 1

Which type of automated storage and retrieval system (AS/RS) uses cranes that travel along a fixed aisle to store and retrieve unit loads?

Accepted Answer

Unit-load AS/RS

Answer

Unit-load AS/RS systems use aisle-bound storage/retrieval machines (SRMs) or cranes to handle full pallets or large totes in high-bay racking.

Question 2

In a WMS, 'cycle counting' using ABC classification means:

Accepted Answer

Counting high-velocity (A) items more frequently than slow-moving (C) items

Answer

ABC cycle counting prioritizes frequent counts for high-value or high-velocity A items, reducing counts for B and C items to focus effort where accuracy matters most.

Question 3

What does 'lot traceability' in a WMS enable a warehouse to do?

Accepted Answer

Link products to their specific production batch for recall or quality purposes

Answer

Lot traceability allows the warehouse to record and query which lot or batch a product came from, critical for recalls, expiration management, and quality control.

Question 4

A 'goods-to-person' (GTP) fulfillment system improves productivity primarily by:

Accepted Answer

Bringing products to a stationary picker rather than sending pickers to products

Answer

GTP systems (carousels, VLMs, robotic shuttles) deliver inventory to an ergonomic workstation, eliminating travel time which can represent 50-70% of picking labor.

Question 5

Which data element in a GS1-128 barcode uniquely identifies a specific shipment unit globally?

Accepted Answer

SSCC (Serial Shipping Container Code)

Answer

The SSCC is an 18-digit GS1 identifier that uniquely identifies a logistic unit (pallet or case) worldwide and is encoded in the GS1-128 barcode.
