MATHEMATICAL MODELS OF SELECTION OF VEHICLES AND THEIR DISTRIBUTION ON TECHNOLOGICAL OPERATIONS
DescriptionThe article describes the models of selection and distribution of vehicles in the life cycle transport company based on the principle of hierarchical modeling for various manufacturing operations
-
Description
In this article, the second group of optimum speed of diagrams of moving actuating device of electric drive of alternating current is described. Parameters, condi-tions of existence and analytical dependences of an angle of rotation of actuating device of electric drive of alternating current on time for each of diagrams are defined
-
Description
In this work, the example of skidding vehicle passes distribution along a skidding trail is considered. The distribution is determined when vehicle capacity is being decreased in skidding process because of rut depth increasing on the soils with low bearing capacity

STUDY OF WORKFLOWS WITH HYDRAULIC CUTTERS TO LOWER HARDWOOD STUMPS AT FOREST SITES
DescriptionIn the article, the dynamic characteristics of frictiondual-tillage of a wood soil-cultivating mill as object of automatic control are presented
-
Description
The variant of the decision of a task of management of a transport resource of buses is submitted on the basis of the current information on a condition of a route. The real speed of movement of transport, change of number of the passengers is taken into account. The considered task concerns to a class of extreme tasks on networks and is complicated by a set of restrictions
-
Description
In the article, application of methods of self-organizing for identification of processes of weight carrying polluting components of underground waters for the purpose of optimization of technogenic loading on environment is considered
-
THEORETICAL SUBSTANTIATION OF CON-STRUCTIVE-REGIME PARAMETERS OF THE COMBINED ARABLE UNIT
DescriptionIn the article, questions of a substantiation and calculation of the basic constructive-regime parameters of the combined arable unit as a part of a plough and rotational working body of active action with a horizontal axis of rotation are considered
-
NUMERICAL SOLUTION TRANSPORT MODEL BINARY ELECTROLYTE IN APPROXIMATION OF OHM'S LAW
DescriptionThe article is devoted to the numerical solution of boundary value problem of the binaryelectrolyte model of transport in membrane systems in the approximation of Ohm's law. Different numerical methods are offered. The main regularities of transfer are established
-
INCREASE OF SOWING QUALITY OF LARGE SEEDS OF FOREST SPECIES BY SYLVULA SEEDING MACHINE
DescriptionThe article examines the process of large forest seeds sowing and adjustment of wide-gate way of sowing with the possibility of choice of sowing machine optimal working parameters
