Question 1

Which slotting strategy places the fastest-moving SKUs closest to the shipping dock to minimize travel time?

Accepted Answer

Velocity-based slotting

Answer

Velocity-based slotting assigns high-turnover (A-items) to locations nearest the outbound dock, reducing picker travel distance.

Question 2

A warehouse uses a 'fishbone' aisle layout. What is the primary advantage over a traditional straight-aisle design?

Accepted Answer

Reduced average travel distance for order pickers

Answer

Fishbone (herringbone) layouts create diagonal cross-aisles that cut average picker travel distance by roughly 10–20% compared to straight-aisle grids.

Question 3

What is the purpose of a 'golden zone' in pick-face design?

Accepted Answer

The ergonomic height range (waist-to-shoulder) where the most active SKUs are stored

Answer

The golden zone (approximately knee-to-shoulder height) minimizes bending and reaching, so placing fast movers there reduces pick time and injury risk.

Question 4

In warehouse layout planning, what does 'clear height' refer to?

Accepted Answer

The usable vertical space from floor to the lowest overhead obstruction

Answer

Clear height is the unobstructed vertical dimension inside the building, which determines the maximum rack height and cubic storage capacity.

Question 5

Which type of racking system is best suited for storing products that require strict first-in, first-out (FIFO) rotation without a pallet-mover entering the rack?

Accepted Answer

Pallet flow (gravity flow) rack

Answer

Pallet flow rack uses gravity rollers so pallets load from the rear and automatically advance to the pick face, ensuring FIFO without forklifts entering the lane.
