Methodical recommendations for resource intensity derating of technological processes of automobile transportations due to a justified reduction in the number of staff of repair personnel are made. The main methodology for justifying the required number of repair personnel is the dependence of the average monthly mileage and labor intensity of maintenance and repair of the vehicle taking into account its age and performance characteristics.

The article is devoted to the problem of the reduction of the noise nuisance on the inhabitants of areas adjacent to the railway on the basis of implementation of the new technology of high-speed grinding of rails. This technology allows to reduce the self-noise of the rolling stock as due to the removal of various geometric defects of the rail profile, and due to the formation of the required surface roughness after machine working.
According to the Development Strategy of seaport infrastructure of Russia till 2030 the formation of innovative infrastructure of seaports is necessary. One possible solution of this problem is the formation of decision-making support system of the port dispatcher service. The analytic hierarchy process is represented the more reasonable solution of multi-criteria problems in the complicated situation with hierarchical arrangement. The possible method of application of tables of Saaty for a choice of an optimum logistic chain is considered in the article.

The design procedure of reliability indices and longevity of tractive rolling stock details by nondestructive testing results is explained. The testing is realized on the example of nondestructive testing results of gearwheels, wheel centers and wheel pair axes of the VL80. The data obtained when carrying out the repair of electric locomotives in the Petrov Val depot of the Privolzhsk railway were used for calculations.

The modern appraisal plan of production and company competitiveness taking into account the functioning characteristics of an economic player in the freight transportation market is presented.
The construction way of the modified weighed sum code possessing the improved characteristics of error detection in information vectors in comparison with the classical and modified Berger codes is offered. Improvement of characteristics is achieved by establishment of inequality between categories of information vectors and the subsequent procedure of the modification described in the article. At values of information vectors m?8 the new codes don't detect less than 10% of twofold errors.

The basic mechanisms underlying the IBM safety concept are considered; the audit functions of DB2 and DB2access resource managers, such as SAF and RACF.
The article deals with the construction of a measurement model for control objects with a large inertia. The model represents the sequence of operations that must be performed at the monitoring object to measure the pickup or drop-away voltages. The construction of the model is based on the use of series. The implementation of the model made it possible to shorten the time of measuring the pickup or drop-away voltages in comparison with the adopted technology of testing the first class reliability relays.

Chemical analysis researches of samples of materials with estimation of thermodestruction and thermal stability indexes are executed. The thermogravimetric analysis is carried out.
The mathematical model applied to calculation of inhalation effect is adapted for calculation of arrival of substances in the organism of workers while performing work duties. The comparative analysis of calculation results of the average daily potential dose of the main chemicals is carried out. These chemical substances are contained in air of the working zone and included in detergents used in case of the outside washing of the rolling stock.
