Community Detection in Action: Identification of Critical Elements in Infrastructure Networks

Capacity of Main Railway Lines – Analysis of Methodologies for its Calculation

“…Both presented methodologies have their pros and cons, which are consistently derived from this text. Despite different calculation methods, both methodologies have the same results (i.e., numerical versus percentage), declaring degree of occupancy according to (2), respectively the occupancy time rate according to (6), as well as the use of the permeable performance according to (3), (4) or capacity consumption according to (5).…”

“…"The capacity of the railway infrastructure is determined by the number of train paths that can be planned over a certain period of time on a certain part of the railway infrastructure due to the heterogeneity of the train types and the required quality of the train transport" [1], [2].…”

“…Methodology for the calculation of permeable performance within the national conditions is stipulated by ŽSR´s regulation -D24 [2], the methodology within the international conditions for members of the UIC railway union is recommended by UIC Code 406. In this contribution, we will deal with the analytical determination of the practical permeability of the track and its required quality in the context of comparison of the methods stipulated in the above mentioned documents.…”

A New Approach for Measuring the Resilience of Transport Infrastructure Networks

“…Based on network topology-based methods, the value of network distribution p k is the probability that a randomly vertex is chosen in a node with network degree k [48]. e resilience of network can be analyzed by different network topology-based methods, including the networks epidemic disease model [49], the breakdown of network under attacks [50], the networks boundaries [51,52], and the cascading failures in network of networks [53]. In order to analyze the performance response of transport infrastructure networks under different hazards, scholars usually use the network simulation-based methods [18,54].…”

Assessing the vulnerability of infrastructure networks based on distribution measures

“…Transmission System (55). The second is the Great Britain Railway Network (GBRN), described in (56). The third is the Colorado Springs Water Distribution Network (CSWN), introduced in (47).…”
