The problem
Weinig AG is a German engineering company specializing in woodworking machines and systems, providing solutions for the industrial production of solid wood and wood-based products. The company faced significant challenges in spare parts planning, characterized by high manual effort and a lack of transparency regarding inventory levels and demand across its production sites. Different planning and procurement methods within various business units led to redundant processes and excess inventory. At the same time, inaccurate safety stock levels negatively impacted the availability of critical spare parts. While certain parts were frequently out of stock, there were also substantial surplus inventories and high write-offs.
