Whittle Simultaneous Optimisation (SIMO)

Simultaneous Optimisation (SIMO) finds a higher NPV by optimising the schedule, cut-off grade, stockpiles and blend at the same time instead of one after the other. This course starts with the economics behind it (discounting, NPV and how Whittle treats costs) and the conditions where SIMO adds most value. You then add SIMO nodes under a bulk blend scenario, an extractive blend scenario and an operational scenario, compare each against its parent node's NPV, read the schedule reports, export mining sequences and examine how the NPV and mill feed grades are built up.
