<sub><i>Entropijno-information estimations in the field of nonferrous metallurgy</i></sub>
<i></i><sub><i>Use of a measure of definiteness and uncertainty of the information allows to analyze the general mechanisms of entropijno-information laws of the technological repartitions which are a fundamental basis of all spontaneously proceeding processes of accumulation of the information which lead to self-organising of technological processes, namely, to hierarchical systems. The considered approach, in our opinion, completely corresponds to the basic requirements of the system entropijno-information analysis as provides at modelling of hierarchical system of technological processes integrity of its consideration at the expense of the general-theoretical and methodical concepts allowing entirely to keep in sight all system as a whole for the decision of a problem at all levels of hierarchical system.</i></sub>
