Warehouse Design & Operations Flashcards

A warehouse is implementing a cycle counting program. What is the primary advantage of cycle counting over an annual physical inventory?

Answer: It provides ongoing inventory accuracy without shutting down operations for a full wall-to-wall count

Cycle counting audits a rotating subset of inventory continuously, catching errors sooner and maintaining accuracy without the cost and disruption of a complete stop-and-count.

What warehouse design principle does the 'I-shaped' flow pattern (straight-line from receiving to shipping) most directly support?

Answer: Minimal cross-traffic and a clear, linear material flow through the facility

The I-flow (straight-through) layout places receiving and shipping on opposite ends, creating a direct, conflict-free path that simplifies traffic management and material flow.

Which KPI measures the average number of times inventory is sold and replaced over a given period?

Answer: Inventory turnover ratio

Inventory turnover = Cost of Goods Sold ÷ Average Inventory Value; a higher ratio indicates faster-moving stock and more efficient capital use.

A 3PL warehouse provides 'value-added services' (VAS). Which of the following is an example of VAS in a warehouse context?

Answer: Kitting, labeling, or light assembly performed on products before shipment

VAS such as kitting, price-tagging, display-building, or repackaging add customer-specific value to products within the warehouse before they ship.

In a multi-level pick module (mezzanine picking), what is the main operational benefit compared to floor-level picking in a single-story rack?

Answer: Significantly higher pick-face density by utilizing vertical space to create multiple picking levels

Pick modules stack multiple levels of pick faces vertically, multiplying the number of SKU positions accessible to pickers within the same floor footprint.

What is the purpose of 'labor management standards' (LMS) in warehouse operations?

Answer: Establishing engineered time standards for each task to measure and improve workforce productivity

LMS uses engineered time standards (often from industrial engineering studies) to set expected completion times per task, enabling managers to track productivity and identify inefficiencies.

Which warehouse technology uses radio frequency to automatically identify and track tags attached to pallets or cases without line-of-sight scanning?

Answer: RFID (Radio Frequency Identification)

RFID readers communicate wirelessly with tags embedded in labels or packaging, enabling bulk reads of multiple items simultaneously without requiring direct scanner line-of-sight.
