GENERALIZED ACCURACY AS A MEASURE OF QUALITY SYSTEMS OF EXPERIMENTAL DATA PROCESSING WHEN ROUGHNESS ANALYSIS IN THE AIRCRAFT INDUSTRY

Abstract

Information technology, which uses the concept of generalized precision systems of experimental data processing, which is characterized by a given set of indicators of measurement theory and reliability, with the definition of savedocument (zavadoski) and electromagnetic compatibility, can be used when designing systems for measuring the parameters of signals and noise of various kinds. Study of characteristics of problem areas of the aircraft (Problem area - PRAR) is not possible without knowledge of the properties of the measuring signals and noise at the input of the systems of experimental data processing (CONN), often described by probabilistic characteristics.

Most research methods PRAR provide only probabilistic characteristics of signals, mathematical models which are stochastic processes-PRAR that describe interference during signal transfer.

When working with deterministic signals, such as direct measurements of the roughness of surfaces and some others, the received signals are the mixture of dimensional deterministic signal and noise obtained from the action of the environment on the signal (signal attenuation).

The concept of generalized precision could serve as a basis for development of methodical, software and technical support for statistical multiband and multifunctional systems of experimental data processing in the study of the roughness of the products of aviation technology with a given tolerance, and metrological certification and verification software and verification capabilities of statistical measurements can be carried out according to specified rules.

Key words: mathematical model, information technology, generalized precision, the system for processing experimental data.
