|Ore loading and transport can constitute some 50% of the total operating costs in a typical opencast mine. Any small reduction in these components can therefore result in substantial savings in the total cost. In this paper, a mathematical model is introduced that aims to optimize equipment allocation in opencast mines. In this model, optimization of loading and transport machinery is carried out using goal programming with Fuzzy constraints. Since in a typical mine the output of any loader can be variable, Fuzzy values have hence been used for all variables. The devised model has been tested in Sarcheshmeh and Songun copper mines of Iran. Both mines are amongst the largest operations in the world. The flexible allocation system, prescribed by the model, resulted in 15% increase in the mine output, as opposed to the rigid method of equipment allocation.
