摘要：The role of information uncertainty in the structure of a technical system is defined. The application possibility of the R. Hartley’s and C.E. Shannon’s approaches in determination of entropy and negentropy of structural content of the system are selected and justified. The connection between entropy and negentropy in the case of system states changes is justified. The determination example of the quantitative values of information that characterizes connection association between entropy and negentropy is done.
