摘要: A new raster‐based GIS model that combines multi‐criteria evaluation and least‐cost path analysis was developed to determine the optimal haulage routes of dump trucks in large scale open‐pit mines. The logic can consider multiple criteria simultaneously (i.e. speed, water body, ore curve, visibility, haul road maintenance) rate adverse factor scores truck movement using fuzzy membership functions. After establishing weights five factors by pairwise comparisons, average score grid be generated weighted linear combination constraint scores. New software, called Dump Traveler, implemented improve availability model. An application Roto South pit Pasir coal mine, Indonesia, showed software provide rational solutions on operations. Moreover, layout available roads evaluated trade‐off between m...
