Abstract There is the analysis of the influence of vertical strengths to scraper during soil digging in the article. Considerated force scheme acting to scraper during the filling in the bucket. Determined the meaning of vertical strengths.
Abstract In the article numerical modeling of process of contournant of the fulfilled gases cooled and sated with oxygen is spent to deadlock development, for the purpose of definition of the guaranteed operating time diesel engine, working with partial recirculation.
Keywords recirculation the fulfilled gases, a diesel engine, factor recirculation, modeling.
Abstract The system of equations of state of the two-phase gas-liquid medium with the bubble structure, that take into account heat and mass exchange between phases have been defined and resolved jointly with the unsteady two-phase flow equations within the fuel pipe. Calculated diagrams of two-phase medium parameters change in flow of the diesel injection system are given.
Abstract The main methods of the efficiency increasing of bulldozer-ripper are considered. The events that equipment manufacturers carry out to improve efficiency are presented. The influence of computer software and satellite systems in work production of dozing and ripping operations is considered.
Keywords bulldozer, efficiency increasing, productivity, leveling, control systems, satellite systems.
Abstract The current trend of unsatisfactory state of economic entities in the road freight transport field makes it necessary to study the methods of implementation of the theory of crisis management in transport. Unpredictable devel-opment of the transportation market led to a loss the control of motor transport enterprises in fluctuations in demand, downturn, the factors of instability and crisis impact.
Keywords crisis management, business entity, the market.
Abstract The article defines the concept of transport efficiency of a large city. Consistently addressed the goals and limitations of functioning transport system in the city. Formed and formalized in a system of inequalities, the basic values of important restrictions on the development of transport systems in cities. The mathematical formulation of the model, the optimal problem of forming an efficient transport system of the city of Perm, and presented a solution.
Keywords transport system, city, model, efficiency.

Abstract It is considered the task of the research of the probabilistic transport floods of region. There are formulated the peculiarities of the formalization of traffic network with the multitude of entrances and ways out for building of simulation model, with the purpose of searching maximal flood. It is informed about composition and assigning of the procedures of simulation model the algorithm of Ford-Falkerson and method Monte-Karlo.
Keywords simulation modelling, probabilistic transport floods, the search of maximal flood, the algorithm of Ford-Falkerson, method Monte-Karlo.
Abstract This article is focused on transport telematic system detailed definition. Also base theory of conception telematic system like alliance system is presented. Criterion function application is described.
Keywords transport telematic system, criterion function, alliance system strategy.
Abstract Method of graphical modeling of steadiness of informational systems (IS), functioning on the special condition in form of unified scheme of functional integrity-transition graph (SFI-TG) is proposed. Composed ambiguity of structure charts, using for formalization of their functioning processes with purpose of following definition of logical function of capacity for work of system by means of computer.
Keywords steadiness, model, capacity for work, structure chart, informational system.
Abstract In article the emphasis on perfection of methodology and automation of inspection of aerodrome pavement for the purpose of working out of strategy of repair work is placed, their classification, proceeding from building practice is specified. The factors promoting intensity of development of damages to aerodrome pavement are considered. Criteria of decision-making in the ways and terms of appointment of reconstruction of pavement are offered.
Keywords aerodrome pavement, inspection of pavement (monitoring), the strategy of works, supporting repairs, management of a condition of pavement.
Abstract The article gives recommendations on the number of optimum criteria for mass quantities of materials and height of the girders of spans on the magnitude of their flight, the dependence of the mass of the spans on the used steels, the fraction of the calculated resistance of steel allocated to the local perception of the live load.
Keywords optimization, spans with an orthotropic plate of the carriageway, the optimum height, the optimal number of beams, the dependence of the mass of the superstructure.
