Information flows in organizational management structures are caused by a number of factors such as efficiency of administrative staff, level of uncertainty of the current state of control object, required level of precision (reliability) to achieve the end result - control objectives. The effectiveness of control system depends on its ability to maintain a certain state of the system within a range of uncertainty. It is an objective reality, because the deterministic condition is theoretically possible, but not practical. Therefore, by examining in more detail the information flows in organization management on the basis of the theory of information, we can identify common ways of increasing the organization controllability, determine the dependence of uncertainty level of the state of the control object on the control mode of that object. Analysis of recent research. Item "information" is closely connected with such important term as "entropy", which is primary in relation to information. Uncertainty is considered as a measure of information. [7] Uncertainty is understood as the problem of deciding under conditions in which certain solutions lead to different results, depending on the probability of influence factors [14]. The entropy in information theory, according to the statement of K. Shennon, serves as a measure of uncertainty of the condition or behavior of the system under these conditions. Comparing given, it can be noted that a measure of uncertainty serves entropy, in turn "information is communication, connection, which reduces uncertainty". Thus, none of these categories is not separate from each other. Leon Brillouin in the book "Scientific Uncertainty and Information" - M.: Mir. 1966. pp. 25 noted that only the "related information" will represent negentropy. In relation to the management process, the concept of "related information" could be understood as a message that has been accepted by subject of management and administrative action were taken in relation to it, which led to the improvement of the control system. The paper [6] contains an axiom "change of intrasystem information occurs so that the growth of negative entropy (measure of order) system reduces the entropy (measure of disorder) in the system". Object and purpose. In these studies, it was discussed in detail the processes in the chain - the entropy, information, negentropy, but the balance of the system is possible when there is a feedback of negative entropy to the entropy, and this is one of the goals of the work, the second objective is to determine the system control mode according to the set level of uncertainty of the control object. Conclusions. Stable operation of the open-driven organizational structure is provided by dynamic balance between accumulated therein entropy and negentropy, the balance between them is done through the exchange of information and negainformation. Rate of entropy growth in the system, level of required accuracy of determining the value of monitored parameters, which determine the current state of the system, affects the level of control of the organization.
