In the work the bibliometric analysis of scientific works on definition of concepts "organizational changes" and "uncertainty" is made. There is a steady increase in attention to the problems of organization management in conditions of uncertainty. This emphasizes the relevance of the research topic and the search for interconnected promising areas for future research. The growth of publishing activity made it possible to conduct a qualitative analysis based on a sample of 515 publications (articles and conference proceedings), the authors of which study organizational changes in risk conditions. The articles were selected from the Web of Science in a systematic process of search and selection over the past 5 years in order to obtain the most up-to-date views on the problem. The analysis shows that despite the fact that the main number of relevant publications is growing over time, but in general is contained in journals related to ecology and environmental management. Based on selected publications using VOSviewer, the results of the analysis were visualized to provide a better understanding of key contextual areas and authors of research, publishing activity over the years and the appropriate number of citations.

Uncertainty is seen as a factor that overshadows the decision-making process. The risk manager often considers uncertainty in terms of the decision-making process, estimating decision errors and costs. Important components of uncertainty analysis are qualitative analysis, which identifies uncertainty, and quantitative analysis of the impact of uncertainty on decision-making and communication. Uncertainty analysis depends on the problem. Thus, the uncertainty analysis used in the environmental, economic and general literature covers a wide range of different methods. Given the results obtained, the uncertainty analysis varies from simple descriptive procedures to quantifying uncertainty and more formal decision-making procedures. The authors define and analyze in detail the concept of "uncertainty" in terms of its essence and structure.
