Diagnosing the functional suitability of developing multifunctional automated systems based on a reconfigurable model

The paper considers the problem of low relevance of the diagnostic functional suitability model for multifunctional automation systems in the case of high intensity flow of requests for new automation services. The solution of the problem is changing the contour of diagnosing the functional suitability of multifunctional automated systems based on clarifying the boundaries of the control object. At the same time, the functions of identifying changes in requirements are transferred from external system design (the stage of adjusting management goals) to the stage of structural synthesis of the system model. There is a developed approach for diagnosing the functional suitability of multifunctional automat-ed systems based on the inclusion of additional diagnostic parameters of the requirements changes to the diagnostic model; the use of an adaptive diagnostic model that changes its structure depending on the identified requirements; adding additional mechanisms for collecting data on new needs in the automation. The paper presents a description of the software tool for information and analytical support of the activities of the automated system administration unit developed according to the GOST 59194-2020. The software basis is a database that supports an automation system adaptive model and a set of interfaces for connecting monitoring software (functional status and destination requirements). The mechanisms of collecting requirements data and their application in solving the problem of diagnosing functional suitability are considered. The paper describes the considered approach to the automation control system for communication services operating based on the eTOM model. The using of a monitoring data post-processing module based on processmining technology made it possible to reduce the time required to rebuild the diagnostic model. Increasing the relevance of diagnostic information provides an increase in the coefficient of functional suitability of the automation system by 1–6 % with limited modernization resources. The proposed approach to diagnosing the functional suitability of evolving multifunctional automation systems can be used in substantiating the system, operating and technical requirements for promis-ing systems, as well as in the implementation of system-technical solutions within the framework of their design processes to ensure higher awareness of engineering personnel.
