The invention relates to computing, can be used in the study of random processes, including to determine with a given confidence probability the entropy of control parameters for complex technical systems with redundant elements, and is an improvement to the device according to the author. No. 1259291.

The aim of the invention is to expand the functionality of the device.

The structure of a technical system of arbitrary topology consists of n elements, of which r elements i are connected in parallel in the sense of reliability in S sets. Subject to control are m parameters characterizing the state of the technical system. The reliability of failure-free operation according to the R-th control parameter Pn (t), which is affected by the elements and sets connected in series in the sense of reliability, is determined by the formula
