Development of a new stochastic short-term production scheduling optimisation approach for open pit metal mines

露天矿的随机短期生产计划（STPS）提供了一个新的框架，允许生产计划在地质和采矿条件不确定的情况下稳健地管理风险。STPS取决于采矿（储存过程、多种矿石类型和加工商、废物产生、设备移动性、可行的排序）和地质（原地矿石可变性、地质不确定性、模拟的“未来”品位控制数据）因素。配方需要开发创新的随机目标规划技术和高阶空间随机模拟。STPS对数百万美元的采矿现金流产生重大影响，并影响到环境的可持续性。该项目是澳大利亚一些最大的矿业公司的战略优先事项。

Stochastic short-term production scheduling (STPS) in open pit mines provides a new framework allowing production schedules to manage risk robustly despite uncertainties in geological and mining conditions. STPS depends on both mining (stockpiling process, multiple ore types and processors, waste production, equipment mobility, feasible sequencing) and geological (in-situ ore variability, geological uncertainty, simulated 'future' grade control data) factors. Formulations require development of innovative stochastic goal programming techniques and high-order spatial stochastic simulations. STPS has a major impact on multi-million dollar mining cash flows and affects environmental sustainability. This project represents a strategic priority for some of Australia's largest mining companies.
