The problem of production planning in open pit mines

摘要

The variables in open pit mine production interact in a circular fashion, that is, without knowledge of one variable the next variable in the circle cannot be determined. fixing or assuming the values of one or more variables along this circle will lead to inferior planning. An efficient plan will require simultaneous solution to the variables in the circle. However, such a solution is not easy to obtain due to complexity and shear size of the problem. During the last three decades, partial solutions have been found using operations research techniques and heuristic algorithms.
