Abstract The conditional work of the driver performed at wheeled vehicle braking control is determined. The dependence of maximum effort on pedals from the maximum wheeled vehicle movement speed is determined, and it is offered to use the conditional work of steering on brake pedal as a generalized for brake control assessment.
Keywords effort, brake pedal, braking control operation, wheeled vehicle.

Abstract In work the problem of influence of the human factor is displayed at management of a road vehicle. The decision for an exception of some of them on an example of the car a gazelle by means of it роботизации is offered. Noted their functional advantages and disadvantages.
Abstract The analysis of technical and economical parameters of cogeneration systems working on biomass gasification products is presented in the article. Energy and economic efficiency parameters systems based on internal combustion engines, syngas generating reactors and modular cogeneration systems are estimated.
Abstract The article presents derivation and following evaluation of the formula for determination of the of the internal-combustion engines, depending on the volumetric part of air in the fuel mixture.
Keywords internal-combustion engines, type of the fuel, recirculation, indicated measures
Abstract In article there is description different politics of supply management. Work of a warehouse in the form of "birth-death" process is presented, formulas of calculation indicators efficiency of maintenance are resulted by spare parts. The analysis of results calculations function of distribution a waiting time and ways of transformation congestion models.
Keywords birth-death model, service level, an error of transformation, service parts.
Abstract The way of automatic control is developed on the basis of construction of structural model of an automatic regulator of coupling weight of the tractor-tower of air courts with the brief description of work and research of stability of hydraulic system. The basic limiting factors of size of loading in addition effort to a frame of the tractor are considered. Application of automatic control raises efficiency of carrying out of towage on all parameters.
Keywords Automatic control, the tractor-tower, coupling weight.
Abstract In article necessity of the account is proved at an estimation of efficiency of reproduction of road constructions of the stochastic approach to forecasting of their transporting-operational condition.
Keywords Reproduction strategy, road construction, the stochastic approach, efficiency estimation

Abstract The article considers the subject of convolution of business processes effectiveness indicators. To evaluate effectiveness of the development programs, the authors suggest using the concept of strained option. The authors define and solve the problem for effectiveness estimation of the joint investments distribution in circumstances of parameterization of the business processes with mixed funding.
Keywords aggregation, convolution, operating cycle, business process.
Abstract World's leading transport companies have realized that success achievement in competition on different markets is impossible without using modern IT. Development of ready program solution on high quality level and in-time requires high-end professional knowledge and great experience in this scope. From solu-tion of this problem depends present and future of every transport organization.
Keywords Transport organization, "net" information system, business-processes, IT, competition.
Abstract Mathematical model for reliability estimation of the recoverable ASIPM with the partial control of the equipment in the periodic prevention and the average period of preventive maintenance defining algorithm were developed, ensuring maximum availability of the system. Periodic preventive maintenance procedure requirements were identified on the basis of mathematical modeling system.

Abstract The article deals with the subject of organizational structures models building. The process for organizational structure development is considered as an iterative-cyclic process which is implemented under structural-parametric description as object design by means of and/or graphs. In addition, the article describes usage of fuzzy sets instruments, which provide more adequate structure parameterization based on expert evaluations of the connection between the structure and the technological graph.
Abstract Paper presents probabilistic methods normalization load of automobile applicable to bridges in Vietnam. Developed computational models of random automotive loads and spans of bridge construction. Performances computational received the correct coefficients to the Vietnam normative automobile loads.
Keywords probabilistic, normalization load of automobile, random columns automobile, terms of service, bridges.
Abstract In article the analysis of road norms on designing of flexible pavement from the point of view of search of possibilities of increase of working life. It is shown that presence vibrating loading doesn't allow to raise essentially durability of road designs known modes. The mode of increase of working life, consisting in drop of levels of vibration of layers of pavement is offered.
Keywords road norms, flexible pavement, vibration, working life.
Abstract On the basis of perfection of normative method of calculation of deposits the formulas are offered for the calculation of descriptions of difficult SSC through maximal main tension. The demonstrations of possibility of the offered decision is completed, in accordance with which the offered model degenerates in the row of the known engineering decisions, that confirms the self-consistency of this model to orthodox principles of engineering calculations.
