Somewhere in the country, a warehouse is facing product stockout and another is facing overstocking. This isn’t necessarily a procurement problem, it is a distribution problem. And it is a problem that is far more common across Indian ecommerce and retail brands than most business owners would like to admit.

There’s a smarter way to manage inventory across multiple locations and it’s called multi echelon inventory optimisation.

In this comprehensive guide, we will explore what multi echelon inventory optimisation is, how it can benefit Indian brands, and how you can get started with your own optimisation.

What is the Multi Echelon Inventory Optimisation Definition 

In simple terms, multi echelon inventory optimisation (MEIO) means that instead of managing stock at each warehouse in isolation, a business can manage all of the stock across multiple locations as one connected system. Each “echelon” is a stage of your supply chain. This includes your business’s central distribution center, your regional warehouse, your last mile delivery hub, and more. Optimisation means making sure the right stock flows to the right level at the right time.

Think of it like water through a pipe network. You’re not only controlling the pressure, but you’re also managing the whole plumbing system.

Most brands start out with one spreadsheet, one warehouse, one reorder point. When you’re dealing with Rs 50 Lakhs in revenue, this system works just fine. At Rs 5 Crore, however, this system of dealing with one warehouse at a time starts to weaken the overall supply chain.

Types of Multi Echelon Inventory Optimisation

Multi echelon inventory optimisation types include deterministic, stochastic, and hybrid models. It can also be implemented through centralised or decentralised systems.

Deterministic Models

Under deterministic multi echelon inventory optimisation, all variables, including lead times and demand, are assumed to be known and constant. Because these models do not take uncertainty or unpredictability into consideration, they are easier to execute. Optimising inventory levels based on predetermined factors is the main goal.

Stochastic Models

Stochastic models are the opposite of deterministic models. They account for variability and uncertainty in demand and supply. These models reflect unknown characteristics, including varying lead times and shifting client demand, using probability distributions. Although they are more complicated, stochastic models offer a more practical method for multi echelon inventory optimisation.

Centralised or Decentralised Systems

In centralised systems, the inventory choices are made centrally, to improve supply chain coordination and optimisation. Centralised systems take the entire network into consideration. Decentralised systems use local data to make independent decisions at different stages in the chain.

Hybrid Models

Hybrid models are a combination of deterministic and stochastic models of multi echelon inventory optimisation. For certain stable parts of the supply chain, the deterministic model works best. The Stochastic model, on the other hand, works best for areas with higher variability and uncertainty.

The Benefits of Multi Echelon Inventory Optimisation

Lower Inventory Costs

When stock is distributed intelligently, you don’t need to over-buffer at every location. Less dead stock means less cash locked up, and there’s less write-off risk! 

Fewer Stockouts

Demand goes during certain seasons, festivals, etc. With good multi echelon inventory planning, especially during high-demand periods like Diwali, you can be sure that you won’t run out of products in the middle of a sale season.

Quicker Deliveries

Stock positioned closer to demand means the last mile distances are shorter. Conducting your multi echelon inventory planning this way makes sure that your business stays on par with competitors. You can also save money on express shipping this way!

Better Demand Forecasting

Multi echelon inventory optimisation leads you to be better at demand forecasting. You need to be able to predict how demand is going to change. Real-time data from multiple stages of the supply chain will give you greater visibility into customer behaviour and market trends.

Cleaner Cash Flow

Moving from single-echelon to multi-echelon thinking often unlocks working capital, because you stop tying money up in inventory that’s sitting in the wrong place.

The brands that have figured out ecommerce fulfilment services in India, the ones consistently delivering in one or two days across geographies, are always the ones running some version of this model.

Why Indian Brands Need MEIO the Most

India is not a small market. The distance between a warehouse in Delhi and a customer in Coimbatore is really long. It costs time and money to move products from point A to point B. To add to that, there is an enormous variation in demand for a product in Tier-1, Tier-2, and Tier-3 cities. Compare how demand changes between these multiple echelons and you see why inventory management gets complicated fast.

The rise of ecommerce has made customer expectations brutal. Two-day delivery is the norm now. To meet that, brands need stock close to customers. That means multiple fulfillment centers. And multiple centers means you’re now operating a multi echelon network, whether you planned for it or not.

Most Indian brands stumble into this complexity and are not entirely prepared for it. They experience overstocking in slow cities and stockouts in fast ones. Ultimately, it becomes a cash flow problem that quietly bleeds margins every quarter.

Which Industries Should Use Multi Echelon Inventory Management?

• Retail: Multi echelon inventory management can help the retail industry by optimising inventory across stores and distribution centers. MEIO can make sure that products are available where and when customers need them.
• Manufacturing: The manufacturing process is complex with multiple production stages. MEIO can optimise how inventory moves through these stages, so that raw materials are always available for production and there is a reduction in WIPs.
• Healthcare: Optimisation of multi echelon inventory means that medical supplies and pharmaceuticals are adequately stocked in clinics, hospitals, and pharmacies. Optimising the multi echelon inventory planning minimises waste and costs in patient care.
• Automotive: The automotive industry supply chain is massive and complex. It involves multiple suppliers, manufacturers and distribution centers. MEIO helps automotive companies to plan their inventory in a way that these echelons work together smoothly and finish and deliver vehicles on time.
• Consumer Goods: MEIO can help effectively manage seasonal and promotional inventory in the consumer goods industry. These companies are the most likely to feel the pressure of fluctuating demand, seasonal variations, and maintaining high service levels.

Companies That Use Multi Echelon Inventory Optimisation

Johnson & Johnson

• This multinational healthcare company adopted MEIO to manage their medical and pharmaceutical supplies.
• The aim was to make sure that critical medical supplies are readily available for patient care.
• Utilising multi echelon inventory optimisation reduced their inventory costs by 25% and stockouts by 30%.

Procter & Gamble (P&G)

• This global consumer goods company implemented multi echelon inventory optimisation in their supply chain, which thereby reduced their inventory costs by 20%.
• They analysed historical data, demand forecasts, and lead times to determine optimal safety stocks at each location.
• This helped P&G reduce stockouts and improve customer satisfaction and cost savings.

Amazon

• This retail and consumer goods giant uses MEIO to improve delivery times.
• Amazon uses AI-driven algorithms to analyse demand and optimise its inventory simultaneously across its network on a global scale.
• Multi echelon inventory management here reduces delivery times, regionalizes stock, and cuts down on holding costs by up to 20%.

How to Get Started on Multi Echelon Inventory Planning

Without overcomplicating the process, let’s look at how you can start the multi echelon inventory planning journey in a few simple steps.

• Map your echelons first. Where are your fulfillment centers? Which cities generate the highest demand?
• Identify your imbalances. Do you constantly run out of stock? Are there frequent instances of overstocking?
• Partner with the right ecommerce fulfillment service in India. Look for providers who show you a centralised view of multi echelon inventory.
• Set up a “safety stock”. This is backup stock, often considered a “buffer”, which is sized according to the location’s demand and lead time.
• Review every quarter. Demand changes frequently throughout the year. Your allocation logic should shift with it.

Figuring out multi echelon inventory planning is a complex task. You don’t have to have it all sorted out overnight. Even optimising the inventory movement from one warehouse to another is the beginning of multi echelon inventory management. As your network grows, gradually grow your inventory management process with it.

Conclusion

You don’t necessarily need big bucks to achieve multi echelon inventory optimisation. Companies that are excelling in MEIO are the ones who stopped treating each warehouse as its own island. They built visibility into their networks. They made smarter decisions when it came to storing their stock. That shift in thinking, where you go from thinking about each warehouse individually to thinking of all of them as a network, is where multi echelon inventory optimisation takes shape.

The earlier you make the decision to implement multi echelon inventory planning in your business, the less catching up you will have to do later.
