Logistics Network Optimization: An Overview
Growth
As your business grows and expands, your supply chain may become more complex, necessitating a reevaluation and optimization.
Understanding Logistics Network Optimization
Your overall goal in logistics network optimization should be to maximize profitability by ensuring your supply chain network design is able to meet the demands of stakeholders, including shippers, procurement managers, and customers. So, an effective evaluation means taking a closer look at all of the individual components that make up your supply chain. This includes:
- Transportation (routes, product shipping methods, carrier negotiations)
- Facility locations (proximity to target market, infrastructure access)
- Inventory management (demand forecasting, product stock, storage space)
- Cost (ROI calculations, scenario analysis)
When It’s Time to Optimize
Every business will run into issues from time to time. However, if you notice an increasing number of challenges ranging from high costs to low, customer satisfaction, it’s probably a good time to consider upgrading your logistics strategies. Here are a few key indicators to look out for.
1. High Costs
High transportation, warehousing, and distribution costs can quickly eat into profitability. If your business is experiencing cost overages in any or all of these categories, network optimization can be a potent tool for reasserting control.
2. Inventory Challenges
If your business struggles to maintain appropriate inventory levels, experiencing either frequent stockouts or costly overstocking of excess inventory, it’s a sign that your inventory optimization and forecasting is in need of a tune up.
3. Dissatisfied Customers
Customer satisfaction is paramount to the success of all businesses. I’ve observed firsthand how a few bad reviews written by angry customers can ruin a business’ reputation. If you are experiencing frequent delivery delays, incorrect orders, damaged goods, or poor service levels, your logistics network could benefit from optimization.
4. Reactive vs. Proactive Decision-Making
If your staff frequently has to adapt spontaneously to address logistics issues, it’s a sign that your network is not running smoothly. The constant need for quick fixes can lead to unnecessary expenditures, rash decisions, employee burnout, and reduced productivity.
5. Abundant Capacity in the Freight Market
When the freight market has abundant capacity, it’s an opportune time to optimize your logistics network. This situation allows you to negotiate better pricing with carriers and improve transportation management.
6. Seasonality
Seasonal trends can have a massive impact on costs and efficiency. Major holidays, for example, present significant profit potential but can be a logistics nightmare if you are not adequately equipped to handle increases in sales. Optimizing your network in anticipation of seasonal peaks or troughs helps manage capacity and maintain service levels year-round.
Of course, you need not wait until you are experiencing the negative effects of a poorly optimized supply chain network to seek improvements. In fact, there can be other, more positive reasons for seeking network optimization:
Types of Logistics Networks
Once you’ve identified which areas of your supply chain are causing the most headaches, you can begin working on your plan to optimize your infrastructure. This could mean a complete change in the type of logistics network you use. There are three main types of networks: direct shipping networks, hub-and-spoke networks, and outsourced networks. Each network type has its unique advantages and challenges, and the right choice depends on your operational goals, customer requirements, and overall supply chain strategy.
Direct Shipping Network
A direct shipping network, sometimes referred to as a direct distribution model, ships goods directly from the supplier to the customer without any intermediate stops. This approach is ideal for businesses prioritizing speed and cost-efficiency in their delivery. Shipping directly to the consumer reduces lead times and minimizes transportation costs by eliminating the need for warehousing and multiple handling stages. However, it requires precise coordination and robust logistics management to ensure timely and accurate deliveries, especially when dealing with large volumes or diverse product lines. Dell Technologies is a well-known example of a company that utilizes a direct shipping network to sell directly to consumers. In addition, many leading ecommerce websites, ranging from Warby Parker (eyewear) to Casper (mattresses) and Dollar Shave Club (personal care products) utilize this approach.
Hub-and-Spoke Network
As its name suggests, a hub-and-spoke network utilizes central hubs where goods are consolidated before being distributed to their final destinations. This shipping model can significantly cut transportation costs and improve service levels by leveraging economies of scale. Centralized control at the hub also allows for more efficient inventory management and routing, reducing the complexity of managing multiple direct shipments. While it offers enhanced control and potential cost savings, the hub-and-spoke network requires substantial investment in infrastructure and technology to maintain smooth operations. The hub and spoke model is commonly employed by commercial airlines, such as Delta, American Airlines and United Airlines, and parcel delivery services such as FedEx, UPS and DHL. However, some retailers and ecommerce sites also utilize the hub and spoke approach. Walmart and Target both utilize regional distribution centers as hubs from which products can be distributed to individual retail store locations. Amazon uses a combination of direct shipping and fulfillment centers which act as hubs in their delivery network.
Outsourced Network
Some companies opt to outsource part or all of their logistics network by partnering with third-party logistics provider (3PL) to handle their transportation, warehousing, distribution, inventory management, reverse logistics or other needs. Companies that choose this route sometimes opt to partner with a 4PL to manage their network of 3PL providers.
Outsourcing logistics to 3PLs or a 4PL provides flexibility, cost savings, and access to specialized expertise that you probably don’t have within your own company. This type of partnership can drive improved visibility, efficiencies, and reduced costs and allows you to focus on the core competencies of your business.
Strategies for Optimizing Your Logistics Network
In addition to an honest reevaluation of your logistics network type, you can implement other strategies into your supply chain optimization plan to target specific needs. Here are a few that I recommend.
Transportation Management
If you lack transportation management technology, implementing a Transportation Management System (TMS) can be a transformative step in the volution of your supply chain. Sheer Logistics has supported many companies by implementing the SheerTMS, driving significant cost savings, creating vibility to shipments and data, and creating efficiency in the supply chain.
Warehouse Management
A Warehouse Management System (WMS) can help to streamline every facet of your warehouse operations, including receiving, storing, picking, packing, shipping and inventory tracking.
Inventory Management
Effective inventory management ensures that the right products in the right quantities are available at the right locations. Gaining control over your inventory reduces holding costs and prevents stockouts, boosting overall supply chain efficiency. Modern Inventory Management Systems (IMS) help you track inventory, control stock levels, handle orders, and generate timely reports.
Technology Integration
Integrating modern technologies such as a TMS, WMS and IMS as well as deploying automation, machine learning, and real-time data analytics, is a key component in successful logistics network optimization. These technologies streamline your operations and allow you to make better decisions. For example, one study conducted by McKinsey and Company showed that integrating AI (artificial intelligence) tech into supply chains could reduce inventory by 35% and lower costs by 15%, leading to a potential 65% improvement in overall efficiency.
Route Optimization
Optimizing routes can reduce transportation costs and improve delivery times. Sophisticated routing software can help identify the most efficient paths, taking into account traffic, weather, and other real-world factors.
Network Redesign
Redesigning your logistics network might involve changing the location of distribution centers, adjusting transport modes, or re-evaluating facility locations. A well-designed network supports operational efficiency and cost savings. For example, Sheer Logistics helped a client that was expanding into a new product category determine where to locate a new production facility and warehouse in order to optimize transportation costs, minimize transportation times and improve customer satisfaction.
Sustainability Initiatives
Putting sustainability on your business’ list of priorities is a great way to save money in the long run, as well as improve public perception. Implementing green practices such as switching to a hybrid or electric delivery fleet and using eco-friendly packaging contributes to sustainability goals. Capturing and measuring your Scope 3 CO2e emissions is a great start toward managing and ultimately reducing them.
Performance Monitoring
Continuous performance monitoring allows you to identify and address inefficiencies quickly. Key performance indicators (KPIs) such as on-time delivery rates, transportation costs, and inventory turnover help track progress and guide optimization efforts.
Collaboration and Partnerships
As noted above, partnering with 3PLs to manage specific supply chain functions, or with a 4PL to oversee management of your entire supply chain can deliver cost savings, efficiency gains, enhanced visibility and control, service improvements, access to business intelligence and more.
Future Proof Your Business with Logistics Network Optimization
It’s important to remember that Logistics network optimization is not a “one-and-done” solution to all a company’s supply chain issues. Instead, it’s an ongoing process that requires strategic planning, continuous monitoring, and a willingness to adapt to changing conditions.
By understanding when to optimize, exploring different types of logistics networks, and implementing effective strategies, your business can achieve significant cost savings, improved service levels, and enhanced operational efficiency.
