A Supply Chain Planning Case Study

  • Very heterogeneous product mix, including fashion items with high seasonality and short lifecycles
  • Global distribution network, including 26 distribution centers
  • Reduced stock and dramatically cut manual interventions, while maintaining high service levels

Project and Objectives

A study showed that Luxottica’s supply chain had the following features:

  • A very large number of models (more than 2,500), items (more than 30,000) and SKU-Locations (more than 600,000)
  • Very heterogeneous behavior i.e. some articles with low seasonality and relatively long lifecycles, and others (such as sunglasses) that behave like fashion items, with high seasonality and a very short lifecycle (in some cases even less than one year)
  • Same treatment for all products with no attempt to optimize product mix
  • Lack of a client service policy
  • Excess user intervention in the planning process
After a software selection process, Luxottica decided to implement a tool to strategically analyse and optimize stock levels. The company chose Service Optimizer 99+, ToolsGroup's service-driven inventory optimization solution, to:
  • Position inventory to promptly satisfy customer needs
  • Allow production to quickly adjust to market changes
  • Reduce inventories and global logistics costs
  • Improve forecast accuracy


ToolsGroup’s Service Optimizer 99+ manages all finished products in a distribution network comprising 5 sites, one central warehouse and 26 distribution centers. With Service Optimizer 99+, Luxottica maintains excellent customer service levels, while keeping minimum stocks and short time-to-market for all their products.

Results & Benefits

The entire Service Optimizer 99+ solution was implemented in six months and achieved the following benefits:

  • In the first six months, Luxottica reduced stock levels by 10% while maintaining the same high service level
  • In the following months, Luxottica was able to reduce manual intervention in the planning process by 50%, while then progressively increasing service levels

Following the success of Service Optimizer 99+ in the finished products implementation, Luxottica extended the use of the ToolsGroup solution to their spare parts operation (frame components and lenses). In less than three months from the project kick-off, the service level has reached 98.5%, with an 80% reduction in back orders, and no simultaneous increase in inventory levels.

“We have always guaranteed a high service level to our clients. The goals set for Service Optimizer 99+ were to reduce stock, to improve stock mix and to further increase our service level - were therefore very ambitious. With Service Optimizer 99+ and the support of ToolsGroup we were able to carry out this project and achieve the set goals”.
