A comparative analysis involving the evaluation of the effectiveness of investment projects can be based on various rules indicating
selection of the most favorable decisions. The dynamic methods for assessment of investment projects discussed in this article, which
consider the possibility of modifying the predetermined investment options, are quite complex and difficult to implement. They are used
both in the construction phase of the new company, as well as in its subsequent modernization. The assessments should be characterized
by a high coefficient of the economic efficiency. The, observed in practice, high dynamic variability of both the external and internal
conditions under which the company operates is the reason why in the process of calculating the economic efficiency of investment
projects, there is a significant number of random parameters affected by high uncertainty and risk. Investments in the metallurgical
industry are characterized by a relatively long cycle of implementation and operation. These are capital-intensive projects and often
mistakenly taken investment decisions end in failure of the investment project and, consequently, in the collapse of the company. In
addition, the applied methods of risk assessment of investment projects, especially the dynamic ones, should be fully understood by
managerial staff and constitute an easy to use, yet accurate tool for improving the efficiency of the company.
