The article discusses an integrated approach based on the use of expert knowledge to develop a conceptual domain model in terms of monitoring the required operational reliability of technical systems. The need to formalize the key task of logistics analysis is necessary to provide support for the operation of equipment and the creation of an integrated logistics system.

Keywords: integrated logistic support, life cycle, functional failure, operational reliability, severity of consequences

Methods of identification of alpha rhythms of the brain are considered. The identification process is rather laborious due to the strong noisiness of the electroencephalograms and their variability. In the article it is proposed to use the ""Caterpillar"" method or the method of singular-spectral analysis, which allows for a more qualitative analysis of different time series, in comparison with the widespread traditional methods.
