Formation of an Algorithm for Regulation of Reliability Indicators of Technical Systems
Abstract
Based on the analysis of the main factors influencing the reliability indicators of technical systems and ensuring their regulated performance, dependencies were formed to determine the extremum of economic efficiency indicators at a normalized value of the probability of failure-free operation. Based on an analysis of design, production and operation conditions, the parameters of the objective function were determined, including for restored objects. Regulation of reliability indicators was presented as a solution to a multifactor optimization problem. The problem of distributing requirements for the reliability of a complex technical system, consisting of statistically independent indicators of subsystems, was formulated as a conditional optimization problem. In relation to the regulation of reliability indicators and criteria for failures and limit states, factors were grouped according to the characteristics and internal indicators of the object of general classification characteristics, their stratification and ranking. The structure and procedure for preparing initial data was formed.
