this research defines reliability assessment method for information systems (hereinafter IS) in geographically distributed organizations. The article starts with the description of reliability indicators and general task formulation. The approach towards the design of a mathematical reliability model for geographically distributed systems based on the reliability scheme in the form of a graph is validated. There is the calculation of reliability indicators for a 3-level hierarchical system in the article. Advantage of the presented model is that it is suitable for both centralized and distributed information systems. In conclusion, there are some examples of implementation of the suggested approach in three geographically distributed information systems and comparison with the similar studies.
