One of the actual problems of the reliability theory is the creation of mathematical models of real technical objects, processes of their functioning and maintenance, and then the development of methods of research of these models with the purpose of obtaining quantitative characteristics. The aim of the work is to develop a method of management of functional reliability of computing systems of military air defense weapons on the basis of a multilevel system of failure models.

The multilevel system of failure models, linking the values of environmental parameters with indicators of reliability of element base of computing system and integrating the received values taking into account introduced multispecies redundancy in integral complex indicator of reliability of computing system is created. A method for controlling the functional reliability of the computing system of the military air defense weapons on the basis of the multilevel system of failure models is described.

The proposed method of the management of functional reliability of a computing system based on a multilevel system of failure models allows to adapt to the dual nature of threats to the reliability of a hardware platform and in the conditions of a complex impact of failures and sustained failures to form a rational, in terms of active means consumption, a set of measures (control actions) to ensure the reliability of the computing system at all major stages of the life cycle of products.
