Application of dependability and risk analysis methods in the process of implementation, prediction and evaluation of electronic equipment radiation hardness

摘要

The relationship between the concepts of "quality", "dependability", "hardness" of products and "risk" is established. The domestic and foreign experience, as well as international, national and industry standards in the field of quality assurance of electrotechnical systems for various purposes are considered. It was revealed that the foreign industry standards in the field of quality assurance of space systems use the term "dependability" (in the domestic terminology it is similar to the notion of "reliability"), including the concept of radiation resistance. The correlation among foreign industry, international and national standards is defined. General information on the main methods of analysis and assessment of dependability and risk, presented in domestic and foreign documents, are considered. The authors of the paper propose to apply the existing developed methodology of analysis and evaluation of dependability and risk for the tasks of ensuring, predicting and assessing the radiation hardness of space systems at all stages of the life cycle.
