Every term, definition, memory hook, and exam trap is written out here so you can review the whole set or print it.
A third-party logistics provider that performs logistics services such as transportation or warehousing for the shipper.
Mnemonic. 3PL does the logistics work. 4PL hires and orchestrates the providers, often including 3PLs.
Exam trap. Calling a lead logistics integrator a 3PL is the trap. If the firm manages other providers and does not primarily operate the assets, think 4PL.
Moving inbound freight across a dock to outbound doors with little or no storage, usually sorting and recombining loads in between.
Mnemonic. Cross-dock means the pallet changes trucks, not addresses inside the rack.
Exam trap. Cross-docking still needs an inbound schedule that matches the outbound plan. It is not a synonym for a warehouse that also happens to ship the same day.
The final leg from a local node to the end recipient. It is often the most expensive and least predictable leg per unit.
Mnemonic. The last mile is short on the map and heavy on the cost.
Exam trap. Do not design the last mile with line-haul assumptions. Density, failed delivery attempts, and delivery windows dominate this leg.
Moving the same loading unit, often a container, on more than one mode without unloading the cargo itself when the mode changes.
Mnemonic. Intermodal keeps the cargo sealed and changes the vehicle under it.
Exam trap. Transloading, which breaks and reloads the freight, is the contrast. If the container stays intact from rail to truck, the move is intermodal.
Assigning storage or pick locations based on velocity, cube, weight, and the way items are ordered together, so travel and strain go down.
Mnemonic. Slotting puts the fast, friendly items where the hands already are.
Exam trap. Slotting is not a one-time rack label. Velocity changes, and a permanent A location for a fading SKU becomes the waste the exam describes.
How completely the usable volume of a trailer, container, or storage location is filled. Weight limits can bind before the cube is full.
Mnemonic. Cube asks whether the box is full. Weight may say stop before the box looks full.
Exam trap. A visually full trailer can still be a poor cube result if unusable air was never the constraint, and a cube-full plan can be illegal if it exceeds axle weight.
The flow of goods backward from the customer for return, repair, remanufacture, recycling, or disposal, including the information that guides disposition.
Mnemonic. Reverse logistics is the plan for what comes back, not a surprise pile at the dock.
Exam trap. A forward missed shipment is not reverse logistics. Reverse starts when product or packaging moves back for a decision.
The days between paying suppliers for materials and collecting cash from customers for the finished sale. It ties inventory and terms to working capital.
Mnemonic. Cash-to-cash is how long your money is out of the house.
Exam trap. Lower is not automatically better if you created it by refusing to hold a component that then stops the line. Read the metric with service and supply risk.
