Ideal location selection for new stone crusher machine and landfill using FAHP and TOPSIS method: a case study in a copper mine

This study presents a practical approach used to find the best location for installing new stone crusher machine and landfill (waste) in Sarcheshmeh copper in-pit mine located southeast of Iran. Fuzzy analytical hierarchal process (FAHP) technique order preference by similarity ideal solution (TOPSIS) are two methods, which applied as part multi-criteria decision making (MCDM) analysis. In first FAHP method was utilized machine, next TOPSIS (in combination with Shannon entropy weighting) selection. The analysis performed using data collected from experts (engineers, specialists, managers). North, South, East, West sides were considered potential alternatives, 21 factors criteria computational obtained results suggested that alternative 3 (East side mine) place machine. Considering solid waste management, demonstrated 1 (North be landfills. Finally, sensitivity carried out examine effects changes weights on results.
