Samisko D. The productivity of quarry trucking

Thesis deals with the systemic influence research of parameters of freightage process by quarry dump-trucks. With this in view: - mathematical models of dump-truck transportation in the homogeneous areas of transport route and traffic route in general and fuel costs determination are worked out. The variables of dump-truck specifications and its interconditionality with the driving speed on nearby areas are taken as; - algorithms that taking into account mathematical models proposed enable the simulation of the process of quarry dump-truck transportation in the areas of transport route are worked out. They determine the productivity of trucking and fuel costs process in the homogeneous areas of transport route and traffic route in general; - mechanism of systemic influence of dump-truck carrying capacity, traffic route travel time, loading and unloading time on the productivity of trucking process that enables the selection of a rational dump-truck is specified; - dependency of the productivity of quarry dump-truck on its carrying capacity, traffic route travel time, loading and unloading time is formalized. This dependency unlike existing, is nonlinear; - scientific principles of thesis attaching the output data of the Open Joint Stock Company "Komsomolske rudoupravlinnya" are approved officially.
