Аннотация: The article shows a technique to quantify information within the structure of a technical system. The structure indicators are accepted as probability states of the system elements that are differentiated into two opposite states according to a qualitative attribute. The author gives mathematical expressions to present calculation aimed at quantification of informational entropy. The technique is based on decomposition of the initial structure into two schemes (series-parallel and parallel-series) as regard to a singular element. The information is quantified for each scheme according to the presented formulae. The final result was obtained by adding quantity of information of each scheme with due account for the information of a singular element. The obtained results were compared with similar values calculated by the method of full enumeration of system element states. Thus, errors of the calculations were defined. The offered method allows selecting a system with a higher efficiency level or structural reliability due to the comparison of entropy values of opposite states. © 2016 IEEE.
