In today's market economy, a large number of organizations engaged in the provision of services aimed at verification of various measuring instruments, such as water meters, gas meters, electricity meters and others. For such companies, it is of interest to expand the scope of accreditation, which will significantly expand the range of services provided. The article presents the algorithm of the procedure for expanding the scope of accreditation with a description of the main stages.

Keywords: verification of measuring instruments, accreditation scope

The article describes the problem of uncertainty estimation by GUM method and Monte Carlo method on the example of educational measuring procedures and the limits of methods applicability. Examples of the transformation of distributions are presented.

Keywords: measurement uncertainty, propagation of distributions, Monte Carlo method, influence quantity

The article is devoted to the development of metrological assurance in the field of experience based on solving optimization problems with the involvement of simulation and statistical models. This technique will improve the accuracy of decisions and reduce the time of development of technology. It is important to establish a system of views on the organization of metrological support of field experience on the basis of a system approach, taking into account the relationship and interaction of the various elements and processes of metrological assurance. The article describes an example of measurement processing of a multifactorial field experiment with application of simulation models, produced on the basis of the identification of correlations, tightness and shape which describe the regression equation or the correlation equation, which allows to obtain accurate solutions.

Keywords: field experience, observation, and optimization technologies, simulation model, regression, correlation, correlation coefficient

We propose a probabilistic and statistical method of estimating parameters of the traction units, which is the creation of acceptable modes of operation taking into account the probabilistic nature of the load, the probability ratios, and other factors that act continuously and systematically change operational characteristics of machine-tractor units. Presents the graphical dependence of the speed of the shaft of the engine SMD-62 degree load and the coefficient of its variation.

Keywords: mathematical expectation, function of communication, frequency of rotation of the motor shaft, the coefficient of variation, the degree of load probability ratio

The result of the application of the statistical quality control and monitoring instrumentation on PJSC Beriev Aircraft Company is described in this article. The analysis of the existing tools of control and management quality in relation to features of technological process of production pipeline systems on which fuel, air oxygen, liquid chemicals on planes therefore the tool kit for increase quality control at the studied enterprise carried out. The developed control leaf for fast and convenient data collection is described, Pareto's chart is constructed, ABC analysis, for the purpose of identification of the special reasons of discrepancies is carried out, the control chart is used to definition of stability process. The program of correcting actions is developed by means of the chart Isikava, in order to eliminate all revealed discrepancies. Introduction of the offered tools in production of systems of pipelines on PJSC Beriev Aircraft Company has provided continuous improvement of quality of products, has certified compliance of these types of systems of pipelines to requirements standards.
