Algorithms may employ dynamic programming and continuous or discrete linear programming and may require quick computer systems to handle numerous variables and constraints. Heuristic methods may assign or dispatch trucks, one at a time, without taking into consideration the present or future behavior of other trucks. Heuristic algorithms may be simple to implement, but in employing incomplete data, the resulting improvement may not be optimal. The latter may require ore in different parts of the mine to be transported and blended together. Plan-driven dispatching tries to meet haulage targets while satisfying production constraints.
Development follows a literature survey which compared different approaches.
