Multi-echelon inventory optimization (MEIO) is a business strategy that focuses on the efficient management of inventory across multiple levels of the supply chain. It is a comprehensive approach to inventory management that takes into account the interdependencies between different levels of the supply chain, such as suppliers, manufacturers, distributors, and retailers. MEIO is designed to reduce costs and improve customer service by optimizing inventory levels across the entire supply chain. By using sophisticated algorithms and analytics, MEIO can identify opportunities to reduce inventory costs and improve customer service. MEIO also helps to reduce the risk of stockouts, which can lead to customer dissatisfaction and lost sales. By taking into account the entire supply chain, MEIO helps to ensure that the right inventory is available at the right time and place. Ultimately, MEIO helps businesses to maximize profits and reduce costs while improving customer service.
