The authors propose a new method for increasing the reliability of radio-electronic equipment, which involves obtaining deterministic reserves for thermal and associated electrical and mechanical loads of electrical components. These reserves should be used as additional indicators for calculating probabilistic reliability indicators at enterprises. The currently used method of calculating using only probabilistic laws of quantities distribution is not subject to practicale verification in tests. Many of the values used in calculations are averaged. The authors show that the use of real coefficients of electrical, thermal and mechanical loads in the reliability analysis of electric components will give a real effect, because developers will be able to avoid violating the modes of their use. Using the latest advances in information technologies in the field of physical processes modeling with the requirement to take into account the relationship of these processes with each other will increase the reliability of the designed radio-electronic equipment.
