Applications of DEA and SFA in benchmarking studies in forestry: state-of-the-art and future directions
(Peer reviewed; Journal article, 2021-05-17)The forestry sector is constantly looking for ways for making data-driven decisions and improving efficiency. The application of Data Envelopment Analysis (DEA) and Stochastic Frontier Analysis (SFA) allow the users to go ... -
Coupling a differential global navigation satellite system to a cut-to-length harvester operating system enables precise positioning of harvested trees
(Peer reviewed; Journal article, 2021-03-30)Cut-to-length harvesters collect detailed information on the dimensions and characteristics of individual harvested trees. When equipped with global navigation satellite system (GNSS) receivers and motion sensors, the ... -
Depth-to-water maps as predictors of rut severity in fully mechanized harvesting operations
(Peer reviewed; Journal article, 2022-03-14)The preservation of the functionality of forest soil is a key aspect in planning mechanized harvesting operations. Therefore, knowledge and information about stand and soil characteristics are vital to the planning process. ... -
The effect of tree and harvester size on productivity and harvester investment decisions
(Peer reviewed; Journal article, 2021-11-02)Long-term machine-derived data sets comprising 140,000 trees were collected from four harvesters of equal age and similar working conditions, into two machine size classes, viz. two Ponsse Bears and two smaller Ponsse ... -
Efficiency drivers in harvesting operations in mixed Boreal stands: a Norwegian case study
(Peer reviewed; Journal article, 2020-06-17)This paper uses Data Envelopment Analysis (DEA) to evaluate how the technical efficiency of forest harvesting operations is influenced by terrain conditions and forest attributes, in addition to exploring the existence of ... -
Pothole detection in the woods: a deep learning approach for forest road surface monitoring with dashcams
(Peer reviewed; Journal article, 2023-12-18)Sustainable forest management systems require operational measures to preserve the functional design of forest roads. Frequent road data collection and analysis are essential to support target-oriented and efficient ... -
Predicting delay factors when chipping wood at forest roadside landings
(Journal article; Peer reviewed, 2018-05-15)Chipping of bulky biomass assortments at roadside landings is a common and costly step in the biomass-to-energy supply chain. This operation normally involves one chipping unit and one or several transport trucks working ... -
Quality variation in comminuted forest fuels delivered during the winter in north Sweden
(Peer reviewed; Journal article, 2020-10-17)Swedish legislation stipulates the precision required for estimates of parameters used to determine the value of various forest fuels. The net energy value of fuel, as it is received, is often used to set the trade price. ...
