Demanding Customers that require high Service Level

Plastic Omnium is an automotive supplier that produces pre-assembled auto parts and delivers them to the assembly line of the car manufacturers.

Providing a high customer service is a key factor for the company success: Plastic Omnium must produce under a mix of Make to Order and Just-In-Time for its automotive customers. With demands that should be satisfied within 5 hours, it is essential to have enough stock of semi-finished products (painted parts) and be able to react very quickly. This translates into a schedule of the paint line that gives the right priority to each product.

The pilot implementation delivered strong results along all these operational KPIs with a running time below two hours. Different scenarios were made by changing constraints and demands, and all delivered satisfactory results, such as 48% improvement in the service level and 67% in capacity usage. The solution allows planners to adjust the schedule depending on the KPI that needs to be optimized.
