The article is devoted to the development of a mathematical apparatus for the state estimation of the integrated security system (ISS) artificial traffic installation (ATI). The article analyzes the state characteristics of ISS ATI. It is noted that the estimates of the mathematical expectation show the general direction of changes in ISS average functioning. The article provides a selection of statistical analysis criteria for ISS ATI. The features of state analysis for ISS ATI are given. It is noted that checking the normal distribution should be a preliminary stage in the ISS ATI state analysis and a significant deviation from the normal distribution law can serve as a diagnostic sign of the of the system non-stationarity. Therefore, such a comparison is a sufficient tool for identifying the differences, and it should be used in the first stage of the analysis of the ISS ATI state, making possible to draw fairly reliable conclusions about the system state. The article presents the developed methodological principles of ISS ATI diagnostics. For stationarity ISS ATI analysis a methodology for diagnostic analysis, which consists in comparing the statistical current (dysfunctional) characteristics and reference implementations of the system functioning, has been developed. In conclusion, it was concluded that the use of this mathematical apparatus in the ATI security systems development makes it possible to significantly reduce the cost of their implementation and significantly increase ISS efficiency when implemented on ATI.

The issue of marketing in the construction industry has always remained relevant. Indeed, it is not easy to design objects so that they bring high and stable income. The paper studies a solution to the problem, based on the use of the iteration method, the ABC - XYZ analysis, and digital filtering. It is based on the well-known principle of the study of complex systems: the sequential division of a complex task into a number of simpler ones. We would like to note that the “classic” ABC - XYZ analysis gives only general results about the profits from construction projects and does not study the reasons due to which these profits are received. In contrast, the proposed tooling allows taking into account the main technical, geographical and other factors typical for profitable construction projects. One of the advantages of the considered approach is that the conventional computer tools - a spreadsheet MS Excel, is used in solution. The paper discusses the advantages and disadvantages of the proposed approach, specifies in which cases it is advisable to use this approach and where to use more powerful and expensive tools - Big Data technology. For better visualization and clarity, the elements of set theory are used in the paper. This methodology is universal, and its use in the energy industry is possible when selecting more profitable types of products.
