When it comes to designing your supply chain network, one of the biggest decisions is do you start from scratch or work with what you’ve already got. Whether you’re planning your first warehouse or adjusting a well-established network, knowing the difference between greenfield and brownfield approaches can make a big difference. 

In this blog, we’ll break down what each approach means, when to use them, and how leveraging supply chain tools can help you in the process. 

What Is Greenfield Network Design?

Definition & When to Use It

Greenfield network design treats your logistics as a clean canvas. No existing warehouses, no inherited layouts, just open space and opportunity. This approach gives you the freedom to build your network purely around your customers’ needs, transport costs, and the level of service you want to deliver. 

You’d typically turn to a greenfield model in situations like: 

✓ Expanding into a completely new region 

✓ Launching a new product that requires a fresh distribution setup 

✓ Running a theoretical “best-case” network scenario to use as a benchmark

How Greenfield Analysis Works 

At its core, greenfield relies on the center of gravity method. You start by gathering customer data like addresses and volumes and then choose how many distribution centers (DCs) you would like to open. The algorithm calculates weighted centers of demand, pinpointing coordinates that minimize aggregate shipping distances. What you end up with is a visual layout of your “ideal” supply chain network. 

In practice, a planner might run a series of simulations: three DCs vs. four DCs, or focusing only on express delivery zones. 

A Real Greenfield Example: When Starting Fresh Makes Sense 

To give you a real-world snapshot, let’s look at how one apparel company in Germany used greenfield analysis to redesign its entire supply chain network. 

The company had been operating with a single central warehouse in Hesse, serving over 250 retail locations across the country. But as demand grew, that setup started to struggle. Deliveries slowed down, customers complained, and the system just couldn’t keep up. So, they made a bold decision: retire the old warehouse, if that’s what the data recommended, and rethink everything from scratch. 

Using Log-hub’s Advanced Center of Gravity App and Network Design Plus App, the team ran simulations without forcing any fixed warehouses into the model. They started by mapping their current setup (the “as-is” model) and then explored multiple “to-be” scenarios. The selected option led to a leaner, smarter network that reduced delivery distances, improved service levels, and, even with higher fixed costs, set the business up for scalable growth.

What Is Brownfield Network Design? 

Definition & Typical Scenarios 

To brownfield design, by contrast, you turn to when you already have a supply chain setup in place, but it’s time to update or improve it. Maybe some facilities are maxed out, others are underused, or maybe you’ve just acquired a new set of warehouses and need to figure out how it all fits together. With brownfield, you don’t throw everything out. Instead, you take stock of what’s working and explore how to adapt around it. Here’s what the process usually involves: 

✓ Lock in your current facilities as your starting point 

✓ Identify potential new locations or closures 

✓ Run optimization models to balance cost, service level, and capacity 

Rather than one single “best” answer, brownfield gives you a range of options. You might get a recommendation to add one new DC and consolidate two existing ones. Or maybe you’ll find that relocating a single site could drastically cut your transport costs. 

Greenfield vs. Brownfield: A Comparative Narrative

Rather than a dry table, let’s walk through a story. Imagine you are a retailer eyeing two opportunities: 

EXPANDING INTO THE SOUTHWEST: No existing DCs. You need to design a footprint that serves new customers cost-effectively. This is a greenfield moment; you would run an unconstrained site selection study, test three vs. four facilities, and choose a network that balances cost with proximity to key markets. 

INTEGRATING A RECENTLY ACQUIRED NETWORK: Your legacy network covers the Northeast, but you’ve just acquired a competitor’s Midwestern warehouses. Here, brownfield analysis shines: you evaluate which of the combined dozen sites to keep, which to consolidate, and where a new facility might salvage service gaps. 

In both scenarios, you might also run a complementary greenfield study to see the theoretical optimum, but then use brownfield to craft a practical evolution plan. 

Why is Supply Network Design Important? 

Supply chains today face rising fuel costs, volatile demand, and sustainability mandates. A poorly designed network can inflate costs, slow deliveries, and undermine environmental goals. Research from the Council of Supply Chain Professionals (CSCMP) shows that analytics-driven network redesigns yield up to 15% in logistics cost savings and 20% faster average delivery times. 

Relying on dated tools leaves too much margin for error. Modern network design tools automate scenario runs, integrate real transport distances (road, rail, sea), and produce interactive maps, helping planners and executives to see where things could be improved, pinpoint the bottleneck in their network and speed up the decision-making process based on reliable data.
