The development of scientific and methodological approach to increase the efficiency of grain road transportation in the region

In goal of this study is to determine the efficiency of the distribution of cargo flows in the implementation of road transport of the bulk stock during the harvesting company. The authors propose a solution to the problem by means of a semantic two-stage model for the transportation of bulk cargo, which reduces the negative anthropogenic impact of vehicles on the density of the soil cover of agricultural land, and also improves the quality and safety of the goods. The authors analyzed general approach to the results of the organization of grain transportation by road transport in terms of the distribution of cargo flows, considered the principles of customer focus, operating both on the basis of a traditional approach and a multi-agent approach. The solution of the task is implemented in the form of an economic-mathematical model based on the well-known minimum element method for developing a sequence for the distribution of cargo flows, taking into account the ratios between the total volumes of production, consumption and capacities of transshipment points. The presence of direct transportation between points of production and consumption of cargo is also important. The multi-stage transport problem of linear programming is implemented based on the use of standard algorithms. A scientifically based economic and mathematical model of the distribution of automobile cargo flows with direct deliveries allowed the authors to determine the degree of influence of additional factors on the sequence of distribution of automobile cargo flows, as well as to obtain economic benefits by reducing the total run of the rolling stock while minimizing its quantity and optimizing its carrying capacity. This scheme ensures the efficient organization of the grain transportation process through temporary storage facilities, as well as the rational and environmentally less harmful use of trucks.
