Z-numbers have been invented five years ago. It was a large step of representing fuzzy logic, however that numbers created much larger problems of how to calculate them or aggregate multiple numbers of that type. In this work, we present the research that is aimed to find the most efficient methods to operate them (aggregate, add, divide). Firstly, it is important to identify all existing methods of aggregating Z-numbers. Secondly, it is needed to invent new methods of how work with them. As a result, there should be a compared set of algorithms. The most interesting techniques should be detailed and summarized. There is also a program that is developed to model the real-word task of decision-making. The paper contains 50 pages, 6 chapters, 13 illustrations, 1 table, 20 bibliography items, 4 appendices
