Addressing the combination of features and properties, characterizing technical systems, and various factors and effects that influence the functionality of technical objects. It is shown that for territorially dispersed clusters functionality analysis, it is necessary to take into account external adverse effects and requires the use of probabilistic models, complemented by principles of the situation-based approach to searching the most crucial objects and revealing the most damaging effects.

The paper considers the solution of problems of structural modeling of pipeline systems that arose in the process of creating an automated information system using methods of graph theory. It describes efficient data storage methods and the basic algorithm for finding all paths between two vertices.
