ASSESSMENT OF THE INFLUENCE OF THE DESIGN ON THE RELIABILITY OF RADIO ELECTRONIC MEANS

The article discusses approaches to ensuring the required level of reliability of radio electronic means when designing the design of products, taking into account the metrological and diagnostic support during their operation. It is known that up to 80% of the current repair time is occupied by the search for defects, therefore, special attention is paid to the influence of the product design on minimizing the average diagnosis time. The quantity of elements of modern radio electronic means is constantly increasing due to the expansion of their functions and automation of technological operations, but the requirements for their reliability remain constant. This contradiction can be solved by increasing the reliability of the element base, which leads to an increase in the cost of the product, which is not always acceptable. Therefore, there is a problem of providing the necessary values of reliability in other ways, including taking into account the requirements of maintainability of products in the design, as well as improving metrological and diagnostic maintenance during operation in real conditions using modern advances in metrology and technical diagnostics. Thus, there is a problem of quantitative assessment of the impact of the design of radio electronic means on their reliability, as well as a reasonable choice of recovery options for maintenance in the minimum time. This will provide the required values of reliability without additional costs during the operation of radio electronic means. Possible options for restoring the operability of multi-output objects, which include power supply subsystems, are considered. It is shown that a reasonable choice of design, metrological and diagnostic support reduces the time of current repair by up to 30%.The use of the results obtained in the design of promising and existing radioelectronic devices for various purposes makes it possible to increase the efficiency of current repairs in real conditions.
