This study attempts to use the analytical hierarchy process to choose the most appropriate earthwork machine for slope classes of 30-50% and 50-70%. Required data were collected by pairwise comparison as questionnaires filled by experts of forest engineering. Results showed that cross-sections and grade line (Technical criteria), soil excavation and displacement (Environmental criteria), production rate and multi-application (Operational criteria), production cost (Economic criteria) with the respective weights of 0.345, 0.345, 0.136, 0.058, 0.058 and 0.058 were the most important criteria for choosing the earthwork machines in the slope class of 30-50%. These coefficients for the slope class of 50-70% were 0.329, 0.329, 0.174, 0.056, 0.056 and 0.056, respectively. Overall priority of bulldozer in slope classes of 30-50% and 50-70% was 0.51 and 0.48, respectively. Therefore, in slope class of 30-50% bulldozer and in slope class of 50-70% hydraulic excavator must be selected for earthwork operation.
