Abstract
The purpose of the study is to develop a methodology for assessing the reliability of data storage systems using RAID arrays based on the mathematical apparatus of fuzzy inference. The methodology allows taking into account various aspects of reliability, including recoverability and redundancy, as well as adapting to data uncertainties, which makes the approach flexible and accurate. The scientific novelty of the work lies in the use of fuzzy inference to assess the reliability of systems with RAID arrays. Unlike classical methods, the pro posed approach allows taking into account uncertainties based on expert knowledge and linguistic variables. The practical significance of the study is determined by the software implementation of the method for assessing the reliability and managing the configuration of systems using RAID systems, which helps to reduce the likelihood of failures and data loss. The main result of the work is the successful implementation of a reliability assessment algorithm using fuzzy logic in the MATLAB environment, demonstrating the possibility of accurately assessing the reliability level and managing the configuration of information systems with RAID arrays, taking into account the uncertainty of parameters and real operating conditions.
