When designing most types of activities, as well as when needed to audit the results achieved, a problem arises to analyze simultaneously data included in the descriptions of individual elements of this activity. The purpose of such analysis may be to identify contradictions among disparate information descriptions of processes included in the general activity, as well as to search for possible ways of improving the results achieved. The paper presents the results of a study of visualization potential in the analysis of large volumes of heterogeneous data. The results obtained have been used in the development of visual research tools which help to improve the design of complex processes and to solve the applied problem of planning the educational process. © 2019 National Research Nuclear University.
