How are scheduling targets defined and how many targets can be used at the same time?
Targets may be defined by either a Rate or Ratio formula: where x, y, z, are attributes and A, B, C, are constants. With these formulae it is possible to construct targets for stripping ratio, ore blending, machine hours, consumptions, mill feed grades, tonnes produced, waste movement, cashflow and so on. Targets are defined with a target value and an upper and lower bound which may be varied by period through the schedule.
