Analytical and computer models of false failure and undetected failure (error functions) were developed with tolerance control of the parameters of the components of the measuring technique. A geometric interpretation of the error functions as two-dimensional surfaces is given, which depend on the tolerance on the controlled parameter and the measurement error. The developed models are applicable both to theoretical laws of distribution, and to arbitrary laws of distribution of the measured quantity and measurement error. The results can be used in the development of metrological support of measuring equipment, the verification of measuring instruments, the metrological examination of technical documentation and the certification of measurement methods.

The article contains the results of the metrological examination and research of the accuracy indicators of a method for diagnosing aircraft gas turbine engines of the D30KU/KP family using an ultra-high-frequency plasma complex. The results of metrological examination of a complete set of regulatory documents related to the diagnostic methodology, and an analysis of the state of metrological support are provided as well. During the metrological examination, the traceability of a measuring instrument (diagnostics) – an ultrahigh-frequency plasma complex – is evaluated based on the scintillation analyzer SAM-DT-01–2. To achieve that, local verification schemes from the state primary standards of the corresponding types of measurements were built. The implementation of measures to eliminate inconsistencies identified during metrological examination allows to reduce to an acceptable level the metrological risks of adverse situations when carrying out aviation activities in industry and air transportation. In addition, the probability of occurrence of errors of the first and second kind in the technological processes of tribodiagnostics of aviation gas turbine engines is reduced when implementing a method that has passed metrological examination in real practice. At the same time, the error in determining ratings and wear indicators provides acceptable accuracy indicators and sufficient reliability in assessing the technical condition of friction units of the D-30KP/KP2/KU/KU-154 aircraft engines.

A basic information carrier in the course of many decades is a package of technological documentation allowing the support of the product correspondence to the requirements specified. For quality continuous improvement it is offered to consider a life term of each machine part as a continuous flow of technologies. A hierarchical structure of technologies (technological routes and operations) is substantiated. As a result a possibility arises to adjust tracing the information on parts quality during their manufacturing and assemblage, in motor car application and also at preparation for utilization.

The paper analyzes the technological preparation of production at the railcar enterprises in terms of developing technological processes and processing sets of technological documents. Factors affecting the quality of technological preparation of production for maintenance and repair of rolling stock are considered. In contrast to the previously performed works, where the assessment of the level of technological training was carried out by experts of a scientific organization, the initial data in the article were the results of a survey of specialists of technical departments of structural divisions of the car industry of the Sverdlovsk and South Ural Railways. Based on the method of expert qualimetry, the weight of factors that have the greatest impact on the quality of technological processes is estimated. As a result of the survey, a low level of automation of design processes was established, which consists mainly in the design of technological documentation. It is shown that the degree of depth of development and detail of technological processes is at the level of the route description

The organization of work at the construction site is regulated by the calculated indicators of the consumption of fuel and energy resources. In the process of solving the problems of organizational and technological modeling, factors are determined that, to varying degrees, affect the reduction in the consumption of fuel and energy resources during construction and installation works. The purpose of the study is to determine the factors that affect the reduction of fuel and energy resources at the stage of organizational and technological design. We used the method of expert assessments, method of a simplified approach to average energy costs for individual types of consumers for a certain period of work, specific indicators of the consumption of certain types of resources in a wide range are used. When developing calendar plans and building master plans as part of the organizational and technological documentation, a methodology for summarizing and consolidating a number of indicators is used, most of which have no quantitative measurement. As the results, the variation coefficients are determined for the factors to ensure the activities of construction organizations in the field of energy conservation and energy efficiency.
