In the presented work, the author tries to solve the problems of analyzing and decomposing the failure probabilities of complex technical systems that entail material damage of varying severity, as well as human casualties. This decomposition is a difficult formalized procedure in which a large amount of data is generated, such as the name and description of failures, causes, consequences, manifestations, the probability of occurrence and the criticality of the failure. Critical failure rate is defined as the product of 3 components expressed in scales from 1 to 10 and characterizing the probability of failure during operation; the severity of its consequences and the likelihood of detecting a failure before delivery of the product to the consumer. The operation requires that the participants of the work, firstly, comprehensive knowledge about the investigated object, and secondly, detailed knowledge of the relevant methods and procedures. To effectively decompose a complex product, automation of this process is necessary based on modern approaches to the creation of information systems. The most promising is an integrated approach, combining the methodology of functional modeling of processes in the system and the methodology of information modeling and database design.
