Mathematical modeling of specific energy consumption of machinery and mechanisms for reforestation
Timber harvesting and reforestation are conducted in the same territory almost simultaneously. Therefore, organizing logging operations, forestry and forest industry specialists ought to take all necessary measures to restore the forest within the shortest possible time. They must know the object of their labour - the forest, the nature of its origin, forest conditions in which it develops while shaping the composition, structure and productivity. The choice of optimal technologies of logging and reforestation, machinery and mechanisms usage, the costs of labor and expenses on logging and forestry work depend on these and many other features. Reforestation is an energy consuming process, which requires the use of power efficient technologies and equipment. The energy consumption of different operations is an indicator, which helps to make an objective assessment of processes and machinery. The article represents a calculation methodology for specific energy consumption of several types of machinery and mechanisms for reforestation. The developed formulas and calculations are important for enterprises of a forest complex. The implementation of the methods on justification of reforestation with minimum energy expenditure reduces the cost of production. In further studies it is planned to develop not only other types of machinery and mechanisms for reforestation, but also a complex technology assessment of logging and reforestation processes according to the criterion under investigation.
