On the estimation and selection of the delivery system for metal production

In the paper a multicriterion problem of selection of the delivery system for metal production is considered. The model of trade-off solution has been also taken into account.

Leasing of machinery as a line of development of the agrarian-industrial transportation management

The development of the agrarian-industrial transportation management is impossible without renewal of the stock of cars, machinery and tractors. The results of comparative analysis for various forms of crediting reveal that leasing is one of the most effective ways of investments use.

On the computer-based system of timetable synthesis for Moscow ground public transport

Schedule synthesis is one of the most important aspects of public transport control. The paper is concerned with the main principles and prospective of development of the computer-based system “Timetable” for the city ground public transport.

Yudin Yu.I.
On synthesis (planning) procedure of the expert system foreseeing mechanism

The paper is concerned with an investigation of procedure of synthesis (planning) of the expert system foreseeing mechanism. Such expert systems are meant for providing safe ship control when performing key operations, with the method of branching and boundaries applied.

Kuznetsov A.A., Shishkin D.S.
On the comprehensive material analysis by means of spectrum analysis

The paper is concerned with an extension of the traditional method of emission spectrum analysis for determining the materials quantitative composition. A physico-mathematical model for determining the structural, physical and mechanical properties is proposed. The experimental results for various alloys used in transport are presented. A problem of application of the proposed method of comprehensive material analysis with use of computer-based systems of spectrum analysis.

Eigin Yu.A.
On the principles of the artificial neural network development for relevant problems of railway transport

The paper is concerned with the problem of artificial neural networks (ANN) development. The ambiguity of necessary measure is clearly one of the factors retarding the application of ANN. In the paper the consideration is focussed on double-layered neuron mono-directional networks. Also, a calculation method for necessary measure of the first concealed layer of the considered ANN is presented.

Kuklev D.N.
On efficiency of bypass railway junctions

The paper contains general aspects of a simulation model of a railway junction operation and general ideas of estimation of economical efficiency of building the bypass railway junctions along with brief information of theoretical and practical experience on bypass railway junctions. A more detailed treatment of the issue and some practical recommendation should be made, however it would contradict the brief style of the current paper.

Muhambetov S.B.
On the electric energy usage mode control on the railway transport

In the paper a new concept of automatic system for controlling the mode of electric energy usage on the railway transport is proposed. The development and implementation of such a system should lead to effective control of the electric energy usage mode on railway transport in case of energy and power deficit and should also provide successful performance with minimal damage.

Anan’ev V.P., Fisun V.A.
On functioning stability of the railway transport objects and sub-systems in case of emergency

The paper is devoted to the problem securing functioning stability of the railway transport objects and sub-systems in case of emergency. The measures of security are developed and fulfilled in advance with the prediction results for accidents, natural disasters and other emergencies and the analysis of possible consequences and results of scientific investigations taken into account.

Martynyuk I.V.
On the development of methods for predicting estimates of emergency risks on railway transport

The paper is devoted to study of the relation between the number of emergency cases on the railways and various risk factors. A method of modelling of safety level on transport is proposed which may lead to opportune decisions and minimizing the emergency consequences.

Bezrodnova E.G., Sai V.M.
On simulation of regional service market management in the area of labour protection

The authors investigate a vital issue of development of the mathematical model of service market in labour protection. Such model could form a basis for formulating general principles of estimation the needs of labour protection service and of service manufacturers, namely the centres for labour protection.

Kuzminsky R.A.
On the specific features of floating railway bridges in case of swift current

In the paper the problem of application of the floating bridges-bands including railway bridges in the places of water obstacles with swift current is considered. A technical solution leading to increase in hydrodynamic stability, is proposed.

Emel'yanchik A.A.
Some comments on the modern technologies of building structures reinforcement

The paper is concerned with the analysis of modern technologies of reinforcement for bearing structures by means of new materials on the base of synthetic resins. The main reasons of emergency situations and the necessity of reinforcement are analyzed. As a result of the analysis a conclusion is made that the polymer materials can be applied for restoration and reinforcement of the bearing structures.

On the foundation of parameters estimation for a tamping unit longitudinal displacement drive of the automatic track-machine PMA-1.

In the paper the performance requirements for parameters of the tamping unit longitudinal displacement drive of a new generation automatic track-machine PMA-1 are formulated and justified providing the required output and quality of ballast consolidation with a restriction of dynamic force acting on the machine frame and operator.

Kapranov I.V.
On the generalized method of equilibrium position stability calculation in conservative and non-conservative systems with a finite degree of freedom

The paper is devoted to the generalized method of equilibrium position stability calculation in conservative and non-conservative systems with a finite degree of freedom. The method relies on the formulation of principle of virtual work of second order and the associated concepts of virtual work of second order and the associated generalized forces calculation through virial technique. A refined coefficient of transverse stability is obtained in case of a railcar.
