One of the promising directions of increasing productivity in forestry production is a systematic approach to specifying the process efficiency of the wheeled forwarder based on constructing a single technological connectivity of all performed operations from the initial “loading” to the final “start of unloading”. System analysis allows to form coherent and flexible technological processes as single space-time production structures. The process efficiency of such structures depends on the extent to which the basis of the system analysis is used in assessing the fleet of forestry equipment or its elements. The basis of the unified connectivity of the discrete operations (the movement of the forest machine along the skidding track from pack to pack, setting the crane to the operating position, moving the grip towards the log, grabbing the log on the ground, sorting the log, aligning the pack, moving the pack into the cargo compartment, placing the log into the cargo compartment, installation of the crane into the transport position, and movement along the skidding track) from the position of the system theory is a representation of the functional time of manufacturing a production unit (1 m3 of wood) by operation and its superposition for all production operations. The superposition builds a single functional time for the integrity of the operations performed, in which the target function of the production structure is efficiently implemented. An analytical study of determining the effective performance in the functional time of the production process of the wheeled forwarder is given from the position of the system analysis. The article examines the timing of the work of the Ponsse Buffalo wheeled forwarder in the most typical natural and industrial conditions of the rental base of the Mondi Syktyvkar JSC (middle taiga of the Komi Republic). The method of calculating the total capacity of the wheeled forwarder as a result of performance of all operations (loading, storage, and transportation to the place of unloading) is proposed. The possibility of applying the proposed method of assessing the wheeled forwarder efficiency is shown in terms of implementation of forecasting the total productivity of the forest machine in the functional time of manufacturing a production unit. The method allows you to choose the directions of increasing the labor productivity by synchronizing the functional time of all production operations.
