Komatsu – Codelco • Change how mine operations are planned & implemented • Must consider all vehicles, not only AHS trucks • Complexity increases exponentially with number of trucks “There are hardware restrictions...Information exchanged between trucks and central control is enormous. At Gaby, 11 trucks and 30 pieces of equipment...limit...information transfer.” – Jeffery Dawes, Komatsu Chile
