The system is based on allocation algorithm of nominal tolerances with specified external factors influence and normal law of correlations of the correlations between the main parameters and external influences coefficients. The algorithm uses iterative process tolerance domain mapping to external influence domain and correction of nominal reliability domain boundaries. Also the worst case combination of the whole life circle external influences is used. Product Description popup.authors popup.nrat_date 2020-04-02 Close
