Case Study: Lennox improves service levels and inventory turns with Brookes Supply Chain Solutions

Lennox - Customer Case Study

Lennox Residential Heating and Cooling, a division of Lennox International, faced the challenge of managing a complex and rapidly expanding North American distribution network. Their goals were to improve service levels and optimize inventory, but they were hindered by a daunting multi-echelon supply chain, extreme seasonality, and highly variable demand for hundreds of thousands of SKUs. To address this, they partnered with vendor Brookes Supply Chain Solutions and implemented their SO99+ solution for supply chain planning.

The solution from Brookes provided a flexible, self-adjusting system that used statistical forecasting and machine learning to model demand and set optimized inventory targets at an SKU-location level. This integrated system automated the rebalancing of network inventories and managed deployment, which was crucial for their hub-and-spoke model and highly seasonal products. As a result, Brookes helped Lennox achieve a 16% improvement in service levels and a 25% increase in inventory turns, supporting significant sales and market share growth.
