Michelin is considering going "lights out" in the mixing area of the business that operates 24/7. Currently, personnel with a loaded cost of $600,000 per year are used to manually weigh real rubber, synthetic rubber, carbon black, oils, and other components prior to manual insertion in a Banbary mixer that provides a homogeneous blend of rubber for making tires. New technology is available that has the reliability and consistency desired to equal or ex- ceed the quality of blend now achieved manually. It requires an investment of $3.75 million, with $80,000 per year operational costs and will replace all of the manual effort described above.
