Integrating Production Planning with Truck-Dispatching Decisions through Reinforcement Learning While Managing Uncertainty

Joao Pedro de Carvalho, Roussos Dimitrakopoulos
2021 Minerals  
This paper presents a new truck dispatching policy approach that is adaptive given different mining complex configurations in order to deliver supply material extracted by the shovels to the processors  ...  The approach is tested at a copper–gold mining complex, characterized by uncertainties in equipment performance and geological attributes, and the results show improvements in terms of production targets  ...  The mining complex shares the truck fleet between pits A and B.  ...
