Formalization Of The Impact Of Costs On The Reliability Of Instrument-Making Products


The influence of cost costs on the reliability of products is not in doubt, but the ideas about this influence are more intuitive than scientifically based. Therefore, a formalized assessment of the impact of cost costs on the reliability of radio-electronic equipment is of some interest, which was the subject of scientific research in this article. When evaluating the increase in the cost of production due to raising reliability requirements, it is necessary to choose a certain initial level, relative to which the assessment is made. The ratio of this level of reliability to the designed one can be used as a measure to increase the reliability of the newly developed radio-electronic equipment. In this paper, we derive formulas that demonstrate an analytical link of the cost and reliability of radio-electronic equipment and, under certain conditions, they can be implied to set up the optimal values of the indicators of the probability of failure-free operation and the average time to failure.
