The efficiency of a multi-stage dispatching model depends on the capability of the real-time dispatching algorithm to implement production maximization and quality control goals. In this paper, the formulation, development and validation of a transportation algorithm for real-time dispatching is presented. Needy shovels are selected to minimize the deviation of the cumulative tonnage of each shovel route from the target. Trucks are assigned to needy shovels in order to minimize the total waiting time of both shovels and trucks and maximize production. The dispatching system's response to shovel and truck breakdowns is investigated. The algorithm results in a significant production increase and the running average of each ore quality is kept on target, even in the event of a shovel breakdown.
