Abstract
The paper discusses approaches to the development of effective assessment techniques for monitoring heterogeneity of composition and properties of different environments. Outlined solutions based on the use of concepts and methods of the theory of entropy potentials. With this approach, the heterogeneity of the properties of the objects is proposed to consider as a state of uncertainty in the space of the parameters being analyzed. The proposed evaluations of heterogeneity based on the use of standard statistical characteristics are compact, clear, and convenient for practical use. They are not inconsistent with existing developments but complement and extend their potential. The advantages of the proposed approach are the possibility to describe states of uncertainty a set of interrelated numerical characteristics, each of which corresponds to a certain "level" in the description of these states. The characteristics of a higher level are expressed through the characteristics of the previous levels by taking into account additional parameters in conditions of uncertainty and vice versa. There are methods of obtaining estimates of these characteristics in the presence of small volumes of observations that is relevant to many processes and industries in biotechnology industry. The specific results of the study on the heterogeneity of environments in a number of processes and apparatus in various industries are given.

Keywords: heterogeneity, uncertainty, entropy potentials, monitoring.
