Prioritization algorithms for restoring damaged critical infrastructure facilities

The article is devoted to the development of prioritization algorithms for critical engineering infrastructure facilities repair in order to optimize the process of restoring the resource supply to consumers. Damage caused by external influences of various natures, such as intentional impacts and natural phenomena, is considered. The connected power of consumers (or their number in a simplified case) is considered as a criterion for forming the repair sequence of damaged objects, and their importance is also taken into account. The proposed approach analyzes the topology of engineering infrastructures, considering both the own consequences of failed elements and the complex synergistic consequences of these elements’ failures. The application of the developed algorithms for intentional and natural negative impacts is demonstrated. The restoration sequence generation is illustrated via the example of an electrical network, which is a modified 14-bus IEEE test electrical circuit.
