Improving productivity in forest logging operations while reducing negative impact on soil
and streams has gained increasing attention. Positioning primary extraction routes is crucial …

This article presents a study on the world's first unmanned machine designed for
autonomous forestry operations. In response to the challenges associated with traditional …

The mechanization of roundwood harvesting in Sweden has historically cut costs rapidly.
However, machinery and work methods have conceptually stayed the same since the …

Crane work is the most time-consuming work element in forwarding. Hence, assist systems
like boom-tip control are of interest. The first commercially available boom-tip control for …

Most forest operations are complex problems that require the weights of relevant criteria–
representing trade-offs between various economic, ecological, and social aspects of the …

High productivity in forest harvesting requires efficient forwarding. Planning is complicated
by multiple choices of routes and their order, the number and types of assortments, the …

Designing an optimal machine trail network is a complex locational problem that requires an
understanding of different machines' operations and terrain features as well as the trade-offs …

Tree-level planning is gaining relevance supported by continuous advances in forest remote
sensing methods. Spatial connectivity under spatial optimization methods applied to …

As various methods for precision inventories, including light detection and ranging (LiDAR),
are becoming increasingly common in forestry, planning at the individual-tree level is …

ABSTRACT This paper uses Data Envelopment Analysis (DEA) to evaluate how the
technical efficiency of forest harvesting operations is influenced by terrain conditions and …
