network design

The ongoing need to speed deliveries, reduce risk and improve sustainability while managing expenses drives the need to increase efficiency throughout supply chain networks.

Balika Sonthalia, a partner with the global strategic management consulting firm A.T. Kearney and co-author of the 34th Annual State of Logistics Report, said shippers are increasingly focused on resiliency, which means they need to look at the end-to-end supply chain and optimize the entire network.

"You need to truly understand where you have a weakness and where there is vulnerability," Sonthalia said. "It doesn't mean the issue is exactly where the pain is felt."

Improving Overall Network Design

By evaluating the network as a whole — including sourcing locations and product demand —shippers can improve the overall engineering of the supply chain and increase efficiency. "You can look for opportunities to multi-source to avoid the risk associated with being single-sourced, and you want to make sure your sources are close to your customers," said Amy Ilyes, vice president of logistics engineering for Penske Logistics.

When engineering a network design, Penske relies on proprietary and off-the-shelf technology to model its customers' supply chains and find the ideal sourcing, sites, modes and routes.

Engineers run 'what if' scenarios using different ports, routes, alternate suppliers, and varying levels of inventories and modes of transportation. The models help shippers identify which channels should be served by which locations, optimal supplier base locations, the best ports of entry, and where bricks-and-mortar warehouses should be positioned.

"We've worked with customers interested in micro-fulfillment and opened smaller warehouses closer to where the demand points are," Ilyes said, adding that it is also essential to look at the availability of labor, especially warehouse workers and professional drivers, when considering the ideal locations.

Making Transportation More Efficient

By optimizing the network, shippers can eliminate miles, which Ilyes said increases efficiency, frees up capacity and improves the utilization of equipment and drivers. More importantly, it cuts costs.

Penske reviews its customers' current routing to establish a baseline when analyzing routes. "Then we run an optimization scenario and look at how many fewer miles there are. Because there are fewer miles, drivers will have more hours. Then we develop an optimal schedule and determine the number of drivers, tractors and trailers needed to run the routes," Ilyes said.

Changing business rules could create even more savings opportunities. "Take, for example, retail stores with two-hour delivery windows. If the customer widens that and allows a longer period to make the deliveries, we can usually come up with more efficient routes and increased resource utilization," Ilyes explained.

Another option could be moving to larger equipment. "Maybe right now the routes are run with 48-foot trailers, and there could be an opportunity to go to 53-foot trailers," Ilyes said.

There are also gains to be had by filling empty backhaul miles. "We manage a lot of freight besides our dedicated operations. Usually, when we're putting together any design, our backhaul coordinators help fill empty miles, which is a cost savings opportunity for the shipper," Ilyes said.

The Benefits of Increased Visibility

Sonthalia said visibility into inventory helps shippers make data-driven decisions and increases resiliency. "Inventory visibility helps you build resilience by either preventing something from happening or allowing you to react to it happening. Visibility into inventory allows you to pivot quickly," she said.

Knowing where inventory is located also ensures that shippers deploy it from the correct location. "You don't want to be shipping an order from California to a customer on the East Coast when there is a distribution center in the East," Ilyes said.

Making Continuous Improvements

Once the model is established, Penske runs alternate scenarios regularly to determine when an update is warranted.

Companies with seasonality tend to look at new scenarios twice a year or even more frequently if there is enough variability in the network to warrant it. Other companies typically review their networks annually.

More than ever, supply chains need to be agile and resilient. Control towers deliver the supply chain visibility that underpins agility and resilience, hence shipper interest in these information hubs has increased dramatically. Supply chain control tower implementation in stages starting with less challenging nodes makes these solutions affordable and accessible. Also, today's control towers are more powerful than earlier versions, allowing the ability to integrate disparate data sources and information systems while using technologies like Artificial Intelligence and Machine Learning to improve network visibility and performance.

This new e-book from Penske Logistics explores the multiple benefits provided by control towers. You'll learn what they are and why they provide a more responsive management of inventory at rest and in transit, improved order fulfillment and enhanced network design.

One-way networks provide transportation or interaction in one direction. An example would be a delivery route that has no planned return channel. Some of the points to take into consideration when planning or designing a network include: the optimal number and location of plants and warehouses, the best mix of transportation modes and routes, which customer fulfillment strategy to adopt when preparing e-commerce, and an evaluation of supply chain strategies such as localization, offshoring or nearshoring.

Network optimization is about creating the most efficient and cost-effective supply chain network possible by monitoring performance, analyzing logistics, and implementing tools and techniques to make improvements. It is a set of best practices used to improve the overall performance of a network, cut costs and ensure things are running as efficiently as possible.

What Is Network Design?

Network design refers to the planning and design of manufacturing, warehouse or distribution locations and transportation routes that are focused on speed, efficiency and cost. Sometimes network designs must be updated as a response to supply chain growth or an increase in customer base or to incorporate more sustainable business practices. As an example, a business may choose to reduce waste, save money and shrink its carbon footprint by designing a more streamlined distribution network.

As companies respond to increasing demand for sustainable products and services, the role of supply chain network design in supporting and furthering their green goals is gaining in importance.
