He holds a PhD from Missouri S&T (he did most of his PhD work at the University of Alberta). Dr. Awuah-Offei has extensive experience in modeling and simulation of discrete and dynamic systems in mining. His current research interests include modeling and optimization of energy use in mining. Dr. Awuah-Offei’s recent work includes optimizing cable shovel digging trajectories by minimizing energy per unit loading rate and stochastic modeling of truck-shovel operations for diesel fuel savings. His ongoing efforts explore the effect of power quality on performance and energy needs of electric mining tools like draglines.
