This is a good overview of single-stage optimization vs multi-echelon by Bluecrux:
Plenty of articles have been written about MEIO, but this one from Slimstock is a recommended reading.
What is MEIO?
Multi-Echelon Inventory Optimization (MEIO) is an advanced inventory management approach that optimizes stock levels across an entire supply chain network, rather than focusing on isolated nodes. Throughput has written a quite exhaustive article about this here. This article by O9 is also a useful starting point to understand the concept, benefits and common challenges.
Unlike single-echelon inventory optimization (sometimes called SEIO), which manages inventory levels at individual stages (such as a central warehouse or distribution center), MEIO provides a holistic optimization by considering all supply chain tiers simultaneously.
MEIO is particularly valuable in environments with complex, multi-location supply chains or where products face variable demand and high distribution costs.

Key Benefits of MEIO
Cost reduction: MEIO minimizes holding costs by optimizing stock levels across interconnected locations. By adjusting safety stock and replenishment policies for each “echelon”, MEIO prevents redundant stock buildups in a location without considering the other locations.
Improved service levels: By optimizing inventory across all locations rather than focusing on individual nodes, MEIO helps ensure products are available at the right locations to meet demand. This leads to better fill rates and reduced lead times, directly impacting customer satisfaction and reducing the risk of lost sales.

Complexity of MEIO
Implementing MEIO requires sophisticated tools, data integration, and analytics capabilities. It involves tracking demand, lead times, and stock movements across multiple echelons, such as central warehouses, regional distribution centers, and final sale points.
The complexity of MEIO lies mostly in collecting and analyzing data from all nodes simultaneously. Successful MEIO depends on high data accuracy, strong forecasting capabilities, and system integration.
