Abstract

Context. The main idea is to take into account the possibility of the influence of hidden defects on the reliability of multi-mode radioelectronic equipment with a variable structure, which do not take into account the known methods for calculating reliability indicators. A quantitative assessment of the parameter of the failure flow of products is proposed, taking into account the impact of the accumulation of hidden defects on its value.

Objective. Improvement of the method for assessing the reliability of objects with a variable structure, taking into account the possibility of hidden defects when used for their intended purpose in certain operating modes.

Method. The methodology for assessing the values of reliability indicators of complex technical systems is used. The method being developed is the development of an algorithm for assessing the reliability indicators of multi-mode objects in the direction of taking into account the possibility of appearance and accumulation of hidden defects in subsets of elements of the object, which are not used when it operates in separate modes.

Results. Functional dependencies of partial and complex indicators of reliability of multi-mode objects on the accumulation of hidden defects, which manifest themselves only during maintenance or change of operating modes, are obtained. The solution is formalized in the form of an algorithm that uses the results of trial operation of products as initial data.

Conclusions. The scientific novelty lies in the development of the following innovative solutions: 1) for the first time it is proposed to take into account the presence of hidden defects when assessing the reliability of multi-mode objects with a variable structure; 2) for the first time, functional dependencies of the influence of the presence of hidden defects on the values of partial and complex reliability indicators were obtained and studied. The practical significance of the results lies in the fact that it allows, at the stage of trial operation of radioelectronic equipment with a variable structure, to objectively assess the compliance of calculations with the required values of reliability indicators by taking into account the possibility of hidden defects.
