The objective is to maximize net present value under access and capacity constraints. The problems are currently solved in a sequential way: First, production rates and corresponding costs are initiated. Using this cost structure, a cut-off schedule is determined. Finally, the block sequencing is executed for marginal cut-off grades and pre-defined production rates. This process is repeated until maximum net present value (NPV) is found. However, these problems should be solved simultaneously instead of iterative procedure because production rates and cut-offs cannot be known without block sequencing. In this paper, ore-waste discrimination and block sequencing are optimized concurrently through mixed integer programming (MIP) model. This procedure also considers relationship between capacities and accessibility. To observe the performance of new model, a case study is implemented. An increase in NPV is observed.eninfo:eu-repo/semantics/closedAccessProduction controlSchedulingCapacity constraintsCost structureCut-off gradeMine productionMixed integer programming modelNet present valueProduction ratesSub-problemsInteger programmingConference Object37402-s2.0-84923073978N/A
