The article considers the questions assessing the reliability of mechanical components used in the electronic equipment in the early stages of design. The calculations of failure rates springs shock absorbers according to various methods. It is shown that the use of models failure rates of mechanical elements, taking into account the peculiarities of their structural and technological performance, not only allows us to solve the problem of calculating, but also to ensure the required level of reliability and mechanical components, and containing electronic equipment.
An article represents a comprehensive overview of approaches to capital structure modeling on the example of the public corporation Silvinit. At first, there are provided a short review of the company and of the corresponding industry followed by the description of how the analogues for the company were chosen. The next part of the article gives a step-by-step description of the practical implementation of such models as WACC model, EBIT-EPS, method of operational profit. Monte-Carlo approach is used for demonstrating an influence of the leverage increase on tax and interest payments as well as company's default risk. In conclusion the authors compare the results of different approaches with the current capital structure of Silvinit.
