SCHEDULE OPTIMIZER

OPTIMIZE SHORT AND MEDIUM TERM PLANNING

OVERVIEW

MineSight Schedule Optimizer determines the most productive cut mining sequence to achieve the highest project profitability, and then generates practical short to medium term project schedules. This versatile tool satisfies all project quality, quantity, market, and geotechnical constraints, as well as destination capacities, equipment resources, and economic parameters. Advanced integer programming engines are used to solve optimization/blending and scheduling problems.
