Multi Criteria Method for Determining the Failure Resistance of Information System Components

摘要

The study is devoted to determining the level of failure resistance of the components of an information system in order to increase the reliability of the most vulnerable components. A multi-criteria method is proposed for determining the fault tolerance of information system components. Information system components act as alternatives. Alternatives are described by a set of criteria. Each criteria has its own direction of optimization and a unit of measurement. To obtain comparable scales of criteria values, normalization was done. The estimation of additional coefficients is made. The criteria weights are determined on the basis of expert estimates.
