Моделі ефективності і живучості технічних систем

Abstract

The cost of losses at failures in the modern technical systems repeatedly exceeds the cost of the system. The models of survivability oriented to planning are therefore needed. The models of efficiency and survivability, being fuzzy functions from the cost of the technical system and cost of configuration of refuse are developed. The approach on the base of creation single model for the analysis of efficiency and survivability is offered. Concepts “configuration of modification of the system” and “configuration of fail” are defined. The association of indexes of fail tolerance as intervals of range of definition of survivability function is offered. The example of the system with reconfiguration is considered in the paper.
