this thesis examines the performance of harvesting equipment in british columbia's forestry sector. the study examines two forest stands under canfor ltd. in prince george, british columbia. it uses data from modern monitoring technology, fptrak, to collect real-time data on two feller-bunchers, including their working and idle time. the primary goal is to collect data on the performance characteristics of these two feller-bunchers and determine whether there is variability in machine productivity under similar terrain conditions. the research also aims to identify factors that affect operational efficiency, reduce environmental consequences, and promote sustainability. it also seeks to analyze the productivity and utilization of the harvesting equipment and the amount they harvested. the study helps maximize efficiency, reduce environmental effects, and optimize harvesting machinery in the forestry industry. the results shed light on the variables impacting machine productivity, the effects of technology improvements, and the significance of sustainable forest management techniques. they also offer insightful information about the performance of feller-bunchers in british columbia.
