Optimisation tools for open pit mines such as the scheduling and pit optimisation tools have become cost-effective ways to evaluate open pit mine project as well as improving mine project value. However, algorithms employed by major commercial tools on the market were developed almost a decade ago, or even earlier, without considerable improvement for last decade.In this paper, the author has conducted a review to the technique and algorithms on optimisation tools for open pit mine as well as the major commercial tools on the market. A new scheduling tool and a pit optimisation tool are then presented to improve the scheduling algorithm and reflect the improvement of optimisation technology on pit optimisation.The newscheduling tool incorporates with stockpiles, multiple processes as well as multiple mines into a single mixed integer linear programming (MILP) optimisation model and simultaneously optimises schedule in one optimisation._x000D_
Considerable increase in net present value (NPV) has been achieved for all test cases when comparing with Whittle's Milawa and NPV scheduler.CITATION:Ren, Y, 2013.
