System analysis of technological efficiency of forestry equipment module compositions

Abstract

One of the perspective directions of increasing productivity in forestry production is the application of a modular approach to the formation of forestry machine systems. The modular approach makes it possible to form coherent and flexible technological processes, the technological efficiency of which depends on the extent to which the basis of system analysis is used in the formation of the forestry equipment fleet. The system analysis provides an analytical view of the effective capacity and performance at the functional time of the production process. The article explores the energy and production efficiency of several of the most typical compositions of formation of modules and submodules of timber harvesting operations: trees (feller-buncher module, energy module, skidding module), fuel wood (cutting module, energy module, chipper module, chipper-transporting module), logs with sub-sorting in the cutting areas (technological modules of cutting, delimbing and cut-to-length, energy module, skidding module), three-length (feller-buncher module, delimber module, energy module, skidding module).
