Abstract
Last several years we can see the intensive development of complex systems. Such development generates a lot of publications, giving a theoretical basis for building expert systems. These expert systems find the connection between states of a complex system and its indications. Received knowledge allows making appropriate decisions of the accident-free management. As a rule, destructive actions and harmful influences are random in the system. The analysis of such indicators on the base of the probability theory meets serious difficulties. These difficulties identified by the fact that the indicators are not systematic and do not have a mass character. Therefore, this paper describes an approach for assessing of systems states with the help of the random indicators. These indicators do not have a mass character but related to the states of the system. The appearance of such indicators is assessed on the base of knowledge of the expert group (subjective probability). The states of a complex system are diagnosed on the basis of the subjective probability of the indicators. Based on the proposed theory, an expert system for diagnosing the states of complex technical systems was developed.
