“…An extended factor model, including both absolute factor indicators and relative ones (coefficients), directly characterizing the efficiency of the use of freight transport, will allow a more in-depth analysis of the dynamics of the efficiency of its work and, thus, identify "bottlenecks" in the use of freight transport [8][9][10].…”

The article outlines certain methodological aspects of substantiating ways to increase the efficiency of using freight transport. One of the priority areas in training highly qualified specialists in the economic field is teaching them the most rational and objective methods of analysis, the results of which are necessary for the development and substantiation of real and objective management decisions, the implementation of which in production and financial activities of enterprises will help to increase the economic efficiency of using material resources, including trucks. The system of performance indicators for the work of freight transport includes summarizing and particular indicators. The research results show that the efficiency of trucks has significantly decreased: the truck availability rate by 5.6%, the loaded mileage proportion by 24.0%, the load factor by 26.8%. The decrease in the efficiency of using trucks indicates the need to develop and substantiate optimal management decisions in order to improve the use of trucks. In order to increase the validity of management decisions, it is proposed to use a new coefficient characterizing the level of use of the operating factor of technically ready trucks. This makes it possible to improve the accuracy of calculating reserves and planning the work of freight transport.

To optimize energy costs during the cutting process, a mathematical model is constructed and the calculation results are studied to optimize the cutting process. The proposed model is built for the operation of the rotor of the haulm shredder, but the technique of its construction can be used for any systems in which rotational movements are used to cut plants. A method for constructing a rotation model of the haulm shredder rotor with respect to two centers of rotation is presented. The method is based on the solution of differential equations of motion, the theorem on the center of mass of the system and the energy conservation law. To obtain an analytical expression, differential equations were solved that related the deviation of the cutting element of the haulm shredder from a radial position. Modeling showed that in the operating mode, at an angular velocity co of rotor rotation of more than 100 rad s1, the dependence is almost linear and can be replaced by the formula in the characteristic mass range of rotating knives 0.7-1.5 kg in relation to T ∼ 0.6-0.001co.
