ITLS5250 Chap.4 Distribution Networks and Last-Mile Choices
Distribution Networks and Last-Mile Choices
Distribution design decides which facilities exist, where inventory sits, which origins serve which destinations and how transport and information connect them. This chapter compares centralised and decentralised networks across inventory, facility, handling, transport and service dimensions.
It then distinguishes inventory-holding warehouses, cross-docking and direct shipment before evaluating home delivery, lockers, collection points and retail pickup as last-mile choices with different customer burdens.

Assign products to different fulfilment routes
- 1Segment the products by demand rate, space, value density, lead-time need and handling requirement.
- 1Hold fast-moving screws regionally because volume supports replenishment and local availability matters.
- 1Keep shed panels centrally or at a supplier and schedule direct delivery after the order.
- 1Pool specialist tools centrally because scarce uncertain demand should share one inventory buffer.
- 1Use faster transport selectively when specialist-tool urgency justifies the premium.
- 1Maintain one order view and return policy even though physical fulfilment routes differ.
Key terms
- Demand Pooling
- Combining uncertain demand so positive and negative variation can offset and reduce duplicated safety stock.
- Safety Stock
- Inventory held beyond expected cycle demand to protect service against uncertainty in demand or replenishment.
- Cross-Docking
- Coordinating inbound and outbound flows through a facility with little or no storage between them.
- Direct Shipment
- Sending goods from supplier or producer toward the customer without an inventory-holding intermediate facility.
- Response Time
- The elapsed delay before a customer can receive an order, including processing, picking and delivery.
- Returnability
- The ease with which a customer can return a purchase and obtain the required recovery outcome.
Distribution Networks and Last-Mile Choices FAQ
Does centralisation always reduce availability?
No. Pooling demand in fewer locations can provide higher in-stock probability for the same total safety stock, or preserve availability with less stock. Delivery response may still worsen, so availability and speed must be evaluated separately.
How does facility count affect total cost?
Fewer sites can reduce duplicated safety stock and facility expense, while outbound distance or service penalties may rise. Inbound consolidation, handling, information and automation can change the result, so combine relevant costs at the required service level.
When is cross-docking attractive?
It fits scaled, predictable flows whose inbound and outbound timing can be coordinated. The facility mixes and redirects product rather than storing it, reducing inventory and lead time but increasing dependence on information quality and schedule reliability.
How should I compare last-mile options?
Compare successful-delivery cost, response time, customer travel, failed attempts, capacity, returns and visibility for a defined segment and geography. Home delivery, lockers and pickup move burdens between carrier and customer rather than eliminating them.
Why must returns be designed with outbound delivery?
An outbound route can look efficient while creating a slow or expensive reverse path. Evaluate drop-off access, inspection, consolidation, refund timing and information ownership when selecting the channel. Returnability influences customer value and can reverse the ranking between home delivery, pickup and direct shipment.
Exam move
Draw three paths for every distribution scenario: the product path, information path and return path. Mark where inventory is held and what each facility contributes beyond storage. Compare centralisation using separate columns for safety stock, facilities, handling, transport, response time, variety, availability and returns, because several effects move in different directions.
On last-mile questions, specify the customer segment and geography before ranking options. Audit every claimed saving for a hidden transfer of travel, waiting, stock or exception work. Close with a conditional recommendation and a monitored threshold, such as promised-date performance or expedited-freight spend, that would trigger redesign.
Practise segmenting a catalogue by demand rate, value density, bulk, urgency and return behaviour before assigning routes. Redraw the same network with a warehouse, a cross-dock and direct shipment, then explain what coordination function changes in each version. Separate product availability from delivery response whenever centralisation appears, because pooling can improve one while distance worsens the other.
For resilience, identify the critical node and propose a selective alternative rather than duplicating the entire network. End by checking whether the customer sees one coherent promise across physically different fulfilment paths.
