The research is focused on the study of processes in radio-electronic system that consists of multiple various radio devices, actively used in the conditions of intentional and unintentional interference. The object of the research is models for ensuring electromagnetic compatibility of the total of radio-electronic devices. The research is aimed at finding the optimal plan for the operation of multiple radio-electronic devices so as to increase the efficiency of joint performance by means of readjusting the emittance parameters.
The probability approach is offered to be used for the analysis of state dynamics of the model of radioelectronic devices, built on the basis of the theory of semi-Markov processes. As a result of the application of this approach the models were obtained allowing calculating and analyzing system performance efficiency. These models consider the complex of factors influencing joint operation and are characterized by reliable formalized process description.
The suggested models may help to perform optimal planning of frequency resource so as to reduce the interference level for radio-electronic devices, and in this way to build an efficient radio-electronic system equipped with various types of radio-electronic devices. The suggested models do not only allow to analyse the efficiency of system operation but to solve inverse problems aimed at improving their protection until it reaches the level desired.

Key words: radio system, radio-electronic devices, interference, electromagnetic compatibility.
