    Software for tolerance design
    (Видавництво Львівської політехніки, 2012) Shilo, Galina; Kovalenko, Daria; Gaponenko, Mykola
    Software for tolerance assignment and element selection is presented in the paper. Methods of tolerance design apply mathematical models of tolerance regions in shapes of hyperparallelepiped and hyperellipsoid which makes possible to take into consideration distribution laws of element parameters. The methods allow carrying element selection and tolerance assignment taking into account external influences. Specification of software functional characteristics and input data presentation were stated to provide integration with existing CAD-systems.

    Tolerance design and electronics elements’ selection under external influences
    (Видавництво Львівської політехніки, 2010) Shilo, Galina; Kovalenko, Daria; Gaponenko, Mykola
    Peculiarities of tolerance region forming are being considered taking into account external influences under normal distribution law. Algorithms of tolerance design under given parameters and external factors have been submitted. Relations for elements selection providing costs minimization were taken. Element selection methods are suggested subject to specialties of electronics elements.
