The analysis of the organization of passenger transportation in long-distance traffic in the direction of Center-South. It is known that the transportation of passenger and freight trains on the Russian railway network is carried out on the same tracks, and the dynamics of their growth is ahead of the development of the capacity and carrying capacity of the railway direction in question. In this regard, foreign and Russian experience in the development of growing volumes of passenger and cargo transportation in conditions of infrastructure constraints was studied. The measures of step-by-step development of high-speed and high-speed movement of passenger trains are proposed. The technique of calculation of efficiency of the organization of the considered types of movement of passenger trains on the direction Center-South is resulted.

Finite state machines, being a mathematical abstraction, allow you to perceive information from the control object, process it and give signals to control the object. The disadvantages of the representation of complex production systems by a set of finite state machines include the complexity of carrying out logical and set-theoretic operations on them and the complexity of describing the parallelism that occurs in the operation of complex production systems. When specifying a finite state machine in the matrix–predicate form, due to the information redundancy, it is possible to avoid these difficulties. Matrix–predicate method allows you to uniquely set the finite state machine square matrix, which makes it possible to use the methods of the theory of matrices during the set–theoretic operations on them and it is possible to avoid isomorphism. The paper presents the developed methods of representation of a finite state machine using a multi-place predicate, which greatly simplifies its task.

Mathematic modeling of the state of a thin round disk being heat and force affected is performed. In the central part of the disk the homogeneous field of temperatures is formed. Within the deformation theory of a perfect elasto-plastic solid the quadratic plasticity condition is chosen. The relationships between the radius of the disk, the temperature of the central part of the disk and the external pressure which defines the appearance of plastic zones have been established. For different values of external parameters of the model the stress vector hodograph and the plots of stresses and equivalent stresses have been introduced.

In work area of application for quantitative metrics of databases are considered. Quality control of the database scheme is impossible without numerical indicators. Metrics of the database can be calculated it is automated that guarantees the accuracy and recurrence of such measurements. In article the model for assessment of complexity of the physical scheme for relational database based on metrics of the table of the database is offered. For the offered model by using the method of T. Saati, received coefficients which consider extent of influence of each metrics on complexity of the database. On the example of real projects for databases quantitative measurements of their metrics in MySQL are executed. The comparative analysis of the results obtained for the model of complexity estimates for various projects of physical schemes for databases and the amount of information contained in sql-scripts of these databases are described.
