To the issue of reliability of a unified restoration complex of railway automation and telemechanics 58_2.pdf

The effectiveness of railway transport depends on the throughput and carrying capacity of stations and track facilities, and the effectiveness of the organization of the technological process at the station plays a decisive role. The article discusses the formation of requirements for a specialized recovery system for the safe regulation of train traffic at railway stations exposed to adverse factors, based on a systematic approach. To restore the elements of the railway infrastructure and organize the normal functioning of the devices and systems of railway automation and telemechanics (RAT), it is proposed to use the developed unified recovery complex (URC-RAT). Particular attention is paid to the consideration of the formation of the structure and assessment of the reliability parameters of the proposed URC-RAT. To justify the decision in the interests of ensuring the high efficiency of the structure of the developed system and determining the rational composition of URC-RAT as a complex organizational and technical system, it is necessary to consistently evaluate individual parameters based on the selected criteria. To do this, it is necessary to assess the characteristics of the reliability, survivability and safety of URC-RAT and determine the optimal operational values of the indicators.

The modified lanchester’s model of fighting58_8.pdf

The mathematical model for the system description of military operations in the conditions of highly organized fight is developed. The General case of dependence of efficiency on time, characteristics of opposing units, dependence of superiority coefficient on time is considered. The system of differential inequalities is applied to receiving a recurrent formula. The recurrent formula is used to calculate the average number of sides, to estimate the main characteristics of the system (the necessary number of means, the time required to obtain the given numbers, the change in the coefficient of superiority of one side over the other depending on time). The efficiency of the sides is considered for any functional time dependence for continuous and discrete cases. The coefficient of superiority also depends on the time. For a small time interval in the model, it is possible to actually continuously monitor the change in the mean numbers. Efficiency of the parties and coefficients of superiority are considered as function of time. It is shown that the left and right bounds of interval estimates for the mean numbers have close values for the maximum and minimum efficiencies that differ little from each other. The error of result makes small percent.

Optimizing System Probability-time Characteristics With the Use of the Simulation Model 000_2.pdf

The currently central problem of increasing efficiency of a real-time hierarchical control system through rational resource allocation and reduction of control document development time was considered. The method of constructing a theoretical dependence of system probability-time characteristics (pTcH) on corresponding objects characteristics was described. The algorithm for developing approximate analytical dependencies based on approximation of experimental data obtained through simulation was outlined. In order to optimize pTcH, the task of allocating resources among objects in a hierarchical control system was formally set and solved. The authors show, that the system simulation model can be used as a target function instead of an approximate analytical dependence with the current efficiency of computers. The simulation model includes a lot of experiments. The random values of control document development time were set during each experiment. According to the structure and the algorithm, system characteristics are defined. Application of simulation models enhances the set of complex system design tasks solved with the use of operations research methods

A Comprehensive Approach to the Assessment of the Effectiveness of Software-hardware Complex of the Naval Authorities Functional Activity Automation 000_1.pdf

The Management Centre of the Main Headquarters of the Russian Navy, opened in St. Petersburg, allows continuous monitoring of the situation in the World Ocean. It is a new essential element of the National Centre for Defense Management of the Russian Federation. The Centre consists of the five departments; the Combat Control Department and Constant Activity Management Department are the main ones; they will be monitoring and analyzing the situation. The equipment of the Centre (the software-hardware complex) allows to perform complex calculations and simulations within the shortest possible time. It also allows the Main HQ of the Russian Federation Navy to ensure management effectively in a qualitative manner. The article discusses the approach to assessment of the effectiveness of the hardware-software complex of naval authorities functional activity automation at all stages of the life cycle. The approach also allows researching the influence of the complex functioning quality on the engagement efficiency and the solution of various control tasks of the Navy.
