In the paper it is solved the scientific-applied task of increasing degree of adequacy of analytical reliability models of fault-tolerant radio electronic systems (RES) for solving tasks of reliability analysis and parametric synthesis of RES. These RES are based on majority structure. An analytical reliability model of fault-tolerant RES with reconfiguration of majority structure core, which takes into account the changing rules of voting, is developed. Proposed model of fault-tolerant RES allows us to design the RES, which keep on the principle of majority voting after technical systems failures. Two analytical models of reliability of fault-tolerant RES with two-level principle of majority voting are developed. Improved analytical reliability model of maintained fault-tolerant RES based on majority structure with sliding redundancy and fixed rule of vote, allows solving tasks of multivariate analysis (different variants of the algorithm of redundancy using and disaster recovery strategies). This model can solve tasks of reliability parametric synthesis by finding compromises between chosen parameters of fault-tolerant RES and carry out comparative research of their reliability.
