This paper presents a two-level stochastic scheduling tool. The proposed tool determines the optimal location and size of different schedules through a long-term scheduling as well as the optimal operation strategy for schedules through a short-term scheduling. The proposed scheduling tool considers distributed resources, physical and operational constraints, and blocks as candidates for the extraction. One of the key characteristics of the introduced scheduling is its ability to tackle the two schedules through s...

In open pit mining operations, production scheduling is a hierarchical process for optimization of extraction capacities, resource allocations and types of ore dispatches. Production scheduling deals with equipment capacities, time periods, reserve constraints, wall slope restrictions, ore grade averages and feed controls to mill over a reasonable long-term schedule. Its results then form the inputs of short-term functions more detailed such as scheduling and to control at a lower level which usually has more accu...
