Abstract
Background. The presented study covers key issues related to the assessment of the values of the parameters of functional reliability of an information system under conditions of uncertainty and incomplete information.
The aim of the study is to develop effective methods for assessing the values of the parameters of functional reliability of an information system under conditions of interval uncertainty, ensuring its stable operation.
Materials and methods. The calculation of the values of the reliability parameters of the information system is carried out on the basis of interval analysis methods and basic data processing tools in the case of the type of uncertainty under consideration.
Scientific novelty. In the conducted study, the main approaches to calculating the parameters of functional reliability of an information system are considered in the context of uncertainty described on the basis of interval data, which allows for more accurate assessments and taking into account errors that occur in practice.
Results. The approach proposed in the article has great theoretical and practical significance and serves as a basic tool for calculating the parameters of functional reliability of an information system under conditions of interval uncertainty, allowing one to take into account error factors and determine the permissible intervals of deviation of parameters from the calculated nominal values.
