One of the most overlooked sources of logistics expense is the continued use of a distribution network designed around historical business conditions. Companies evolve. Customer locations change, sourcing shifts between countries, product mixes expand, and transportation markets fluctuate. Yet distribution centers, port routings, and inventory strategies often remain largely unchanged.
Consider a company operating a single distribution center serving customers nationwide. Adding a second facility might reduce outbound transportation expense by $3 million annually and improve delivery times. But if the new facility adds $1.8 million in operating costs and $500,000 in annual inventory carrying costs, the net annual benefit before transition expenses would be approximately $700,000. The decision becomes more complex when you consider service improvements, future growth, additional inventory requirements, and the risk of splitting stock across multiple locations.
Network optimization requires evaluating these trade-offs together. Ocean freight, port selection, rail, trucking, warehousing, labor, inventory, and customer service must be modeled as components of one system. Changing a single variable can produce savings in one area while creating costs in another. The analysis should also consider alternative demand scenarios, changes in freight rates, and the potential impact of disruptions.
The most effective network reviews begin with a basic question: If we were designing this supply chain from scratch today, would we build it the same way? If the answer is no, the next step is understanding what the difference is worth.
For companies with substantial transportation and distribution spending, network design can be one of the most consequential financial decisions they make. The challenge is recognizing when the existing network has stopped being the best answer.
