“…Analysis of the known criteria for comparing the correlation characteristics showed that a statistically significant difference between two estimates of the normalized correlation function or the normalized cross correlation function (coefficients rx() and rxy()) given  is most effectively verified with z -Fisher transformations ( [4]). For this, the statistics are calculated:…”

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.

“…From the author's point of view, the methods of probability theory are most suitable for assessing the reliability of organizational and technological solutions in construction. These methods are widely used in calculating the quantitative value of organizational and technological reliability [9], including in the preparatory period [10], as well as organizational design and project management systems [11].…”

In the current system of contract bidding, there are a number of problems, one of which is the imperfection of the evaluation criteria by which applicants are selected. The article presents a methodology for assessing the organizational and technological reliability of a construction organization and its competitive offers for tenders for construction and installation works. It is proposed to use the indicator of its organizational and technological reliability as a criterion for evaluating a construction organization that claims to fulfill a construction order. To determine the reliability of a construction company, information about the intensity of development of capital investments is used. This indicator allows you to assess how much the bidder can ensure the maximum return on the construction equipment and workers used, reduce the cost of construction using modern construction materials and resource-saving technologies. Each construction and installation organization will have its own intensity of development of capital investments. It depends on the qualification of employees, the availability and use of a fleet of construction machines and mechanisms, construction production technologies, construction organization methods, etc. As an indicator that characterizes the relative change in the actual development of capital investments from the standard or calculated value, the capital investment development index is used. Using retrospective data on the speed of capital investment development for similar objects or using variant design of the construction process, curves of accumulated probabilities of capital investment development indices are constructed, which are used to determine the organizational and technological reliability of the contract bidder. The proposed assessment of the reliability of a construction organization allows the customer (investor) to choose a reliable partner – contractor that best meets their requirements.

“…Literature review on the topic of organizational and technological solutions in construction showed that a huge amount of scientific works has been done [1][2][3][4][5][6]. With the current level of improvement of construction technologies, the most important direction is to increase the quality of the final construction products while increasing labor productivity and reducing all types of associated costs and expenses.…”

Improving the reliability of the implementation of construction schedules for a complex of structures (where the level of quality, timing, and costs is taken into account) can be achieved by creating reserves: time and resources. The reserve of time, the main types of technical, labor, and material resources due to the creation of special structures is in most cases ineffective due to increased costs. Finding the most effective options for creating the corresponding structures from the standpoint of reliability and efficiency is a rather difficult task. An example is given when planning the construction of buildings of a multifunctional complex, a computational matrix is obtained for the flow organization of works. The assessment of the reliability of compliance with the directive deadline for the erection of the mainframe structures are: the critical chain method, the continuous use of resources method, the method of continuous work of front development.
