Doesn NPV Scheduler compete with DATAMINEs own scheduling and blending modules?
No. The two programs complement each other. NPV Scheduler is a long term planning tool which solves the problem of how to sequence the extraction of blocks to meet targets over the life of the mine and deliver the optimal NPV. DATAMINE’s ACHIEVE product is a short term planning tool which solves the problem of which of the available blocks should be mined in any given period to meet the current period target. By using ACHIEVE on its own, you will be able to meet your period to period targets, but without NPVS you will probably reach the point where there is insufficient ore of a particular type to continue blending at the required ratios – short term solutions can create long term headaches. ACHIEVE uses a Linear Programming technique which is well suited to the task of selecting the required mix from a limited number of available blocks or faces. NPV Scheduler on the other hand uses a Dynamic Programming technique which is ideally suited to dealing with sequencing a very large number
