Abstract
ABSTRACT This paper presents a new mathematical formulation to address mine production scheduling with multiple processing streams, under mineral supply uncertainty, and where the destination is formulated as a variable for each block. The proposed mathematical model maximises discounted cash flows and penalises deviations from production targets. A parallel multi-neighbourhood Tabu search metaheuristic is developed to optimise the proposed model. An application at a gold deposit shows the practical aspects and computational efficiency of the model, as well as its ability to provide a schedule that meets production targets and provides a stable destination feed in term of tonnage.
