Abstract
The method of analysis of changes in functional capabilities of the flow network system after the damaging
effects is considered. To describe the processes of streams of different interchangeable products to various peer
users, the model of single-product network is used. The damage is defined as the total amount of unsatisfied
demands. Damage estimates are calculated for all users and all possible cases of failure of physical or logical
elements of the system. Optimal solutions of the sequence of problems of minimization of total relative damages
are used as damage estimates. Based on the obtained results for various destruction configurations, the vulnerability
diagrams of the initial network system are constructed. Diagrams allow an a priori analysis of both small and critical
damages, due to which the flows to some users vanish. The proposed method can be used to study the structural
and functional vulnerability of flow network systems.
