“…Operational performance includes several indicators essential for the planning of forest harvesting operations, such as operational cycle time, productive capacity, among others. There are previous studies on chainsaw logging performance presented by Holmes et al (2002), Cándano Acosta et al (2004), Wang et al (2004), Ghaffariyan & Shobani (2007) and Leite et al (2014). Specifically, in the natural forest of the Amazon region, the works presented by Winkler (1997), Minetti et al (2000), and Batista (2008), developed in the state of Amazonas, stand out where the characteristics of trees to be logged differ compared to those in the state of Mato Grosso.…”
