ABSTRACT

Due to technogenic accidents at nuclear power plants, including the Chernobyl Nuclear Power Plant, part of the forests of the Russian Federation was exposed to radioactive contamination. As a result, it established the conditions under which multipurpose use of forests and forest resources is impossible over the long run. These forests pose a serious environmental hazard due to the possibility of transfer of radioactive contamination to clean areas, because of the occurrence of antropogenic and natural fires. Logging and use of wood from such regions is an urgent issue, which provides environmental problem solving by reducing the possibility of recontamination with radionuclides of surroundings. One of the solutions within the given senario is our proposed technology for the integrated processing of wood contaminated with radionuclides based on internally powered mobile packages of machinery and equipment operating directly on the cutting area or self-propelled vehicles in order to produce clear timber. Herewith, the arisen need to minimize the operating time of machines and equipment is capable of being achieved through the coordinated functioning of cutting machines with mobile equipment in terms of the volume of processed wood at each stage. Coordination of the production volumes of machines and equipment is possible through the creation and maintenance (consumption, replenishment and production) at a specific level of day-on-hand stocks for particular conditions. The operating modes of a set of machines as a whole are determined taking into account previously developed models, providing for an increase in the number and/or shift of machines and equipment functioning in logging operations. This problem solving approach will allow: to ensure the volume of production of a set of machines and equipment equal to the production volume of the leading equipment of the set; reduce the number of days required to harvest a given amount of wood; reduce the amount of pollutants (for example, carbon monoxide) that selfpropelled engines emit into the atmosphere.
