By using data mining and communicating with customers, Komatsu is able to assist mines
in minimizing overtime costs while helping them operate machines at optimum performance
setpoints to prevent unscheduled maintenance.
5 CONCLUSION
Through data analytics and prognostics, Komatsu has evolved its focus from optimizing
the performance of individual pieces of mining equipment to optimizing the systems across the
fleet of equipment deployed in the mine. When the Joy Faceboss products are connected to the
cloud analytics framework, Komatsu is able to drive the continuous improvements that result in
lower operating costs, increased productivity and improved safety throughout the mine.
