e-mail: avladova@rambler.ru; urvladov@rambler.ru.
The article discusses identification of a limited set of conditions of technical objects. Within the limits of the approach processes of damages occurrence and development are represented by marcovian streams of casual events. After that models of an object in the form of an oriented multigraphs are constructed. Their conditions are defined by interval values of a variable, characterizing damages. Probabilities of multigraph conditions are determined by systems of differential equations and a new structural mode based on aperiodic links.
Key words: analogue variables; set of conditions of technical objects; structural mode of multigraphs; structural and parametrical identification.
