A computer model has been developed which is capable of evaluating alternative production schedules (long- and short-range) of an open pit mine once the ultimate pit limits have been defined. The model user can choose the best alternative according to cashflow considerations and the particular mining conditions. The model involves a combination of simulation for long-range production scheduling and linear programming for short-range scheduling.
