USING TECHNOLOGIES OF EXPERT SYSTEMS FOR SECURITY IN INFORMATION SYSTEMS
Description
The article is devoted to the expert systems technology using to monitor the correct operation of the software and databases. It is noted that the main issues of security management in critical information systems is a process of observation and collection of information in a computing environment. Observation results should be evaluated and processed by an expert on security and then recorded in the database of expert systems. One of the possible options for security management of distributed computing network - creating a security machine. It will ensure: minimum response time to external perturbations; the accuracy of the audit protected by S-interface and independent decision-making process of the state of the controlled elements of information systems. After that, the agent is completely worn out; it is destroyed and replaced by a new one. This aging mechanism protects agent from analyzing and from external attacks

Description
This article proposes an approach to teaching mathematics in high school, based on the application of application software packages, which is especially relevant in connection with attempts to transition in the upper grades to profile education, when the student chooses the direction of more in-depth study of subjects, based on his own inclinations. The substantiation of necessity of development of methodical positions and recommendations on use of packets of applied programs on lessons of mathematics in the senior classes of high school is given. The analysis of existing packages of applied programs for teaching mathematics in high school is carried out. During the research, packages used for solving mathematical problems are considered: MS ESCEL, STATISTICA, MATCAD. Known packages of applied programs are classified according to groups of applications in mathematics lessons. Approaches to the use of application packages in math lessons during the pedagogical experiment have been tested. The pedagogical experiment was conducted on the basis of the State Budget Professional Educational Institution of the Krasnodar Territory "Beloglinsky Agrarian Technical Technical School". The analysis of the results of approbation is carried out and recommendations are made on the application of application software packages in mathematics lessons in high school

TO THE QUESTION OF RELIABILITY IMPROVEMENT FOR COLLECTING AND STORING HISTORICAL DATA
Description
The article deals with improving the reliability of data collection and storage of historical data. Investigated the reliability of collecting historical information, the technique, allowing on the basis of general logical and probabilistic methods to identify the most important elements to increase the reliability of which will sig-nificantly increase the reliability of the whole system

CONSTRUCTING A MATHEMATICAL MODEL OF PRICING FOR REAL ESTATE IN KRASNODAR
Description
This study proposes a method of determining the cost of 1 sq. m. apartment on the example of Krasnodar, which is especially important in connection with the necessity of reliable and valid assessment of the property value in a modern market economy. We have performed an analysis of data on apartments in Krasnodar from the site of the Regional Energy Commission - prices and tariffs department of the Krasnodar region. We have also had an exploratory analysis of available data on the subject of emissions and insignificant data (by constructing line graphs and scatter plots); we have also checked for possible dependencies between observations and between variables (built correlation matrix). We have selected variables is linear, the regression model for the variable "cost of 1 sq. m the total area, ths. rub. "(multiple regression). Using regression analysis as a method of mathematical statistics we have revealed a form of analytical dependence of the result of the predictor variables and the degree of this dependence

DEVELOPMENT OF AN EXPERT SYSTEM FOR DIAGNOSIS MALFUNCTIONS OF ENGINES OF DIESEL POWER STATIONS
Description
The article considers development of expert system based on semantic networks for diagnosis malfunctions of the diesel power stations engines. The method allows developing expert systems via objectoriented programming language. The expert system allows to identify the problem without involving additional staff: at the start and overheats of the engine, when there is low power, with decreasing pressure etc

THE ISSUE OF DATA COLLECTION IN ELECTRICITY SYSTEMS
Description
The article discusses the two ways to scaling storage chronological data systems. The formulas for calculating the optimal duration of the period (to split the data by period) and the maximum allowable rate for guaranteed preservation in the system are presented

THE ISSUE SEARCH FOR THE BEST METHODS OF SELECTING THE OPTIMAL POLICY REPLACEMENT VEHICLE FLEET
Description
This article analyzes the best practices of choosing the optimal policy for replacement of vehicle fleet. The problem of replacement equipment was revealed. For each of these methods we gave objective function, constraints. We have found the best method of optimal plan of replacing the vehicle fleet in the company, allowing us to obtain accurate, economically viable new equipment purchase plan during a certain period. We have selected a number of important factors that influence the choice of payment method replacement policy and built PivotTable methods and factors. The selected as part of the research methodology will significantly reduce the labor and time, which will lead to an increase in productivity of the enterprise as a whole. The article gives a practical justification for the need to address the problem of choosing the optimal policy of replacing the vehicle fleet
