Attack Vulnerability of Network Controllability
Controllability of complex networks has attracted much attention, and understanding the robustness of network controllability against potential attacks and failures is of practical significance. In this paper, we systematically investigate the attack vulnerability of network controllability for the canonical model networks as well as the real-world networks subject to attacks on nodes and edges...
متن کاملRobustness analysis of network controllability
Structural controllability, which is an interesting property of complex networks, attracts many researchers from various fields. The maximum matching algorithm was recently applied to explore the minimum number of driver nodes, where control signals are injected, for controlling the whole network. Here we study the controllability of directed Erdös–Rényi and scale-free networks under attacks an...
متن کاملKey to Network Controllability
Liu et. al. recently proposed a minimum number of driver nodes, ND, needed to obtain full structural controllability over a directed network [1]. Driver nodes are unmatched nodes, from which there are directed paths to all matched nodes. Their most important assertion is that a system’s controllability is to a great extent encoded by the underlying network’s degree distribution, P (kin, kout). ...
متن کاملA Study of Car-to-Train Assignment Problem for Rail Express Cargos on Scheduled and Unscheduled Train Service Network
Freight train services in a railway network system are generally divided into two categories: one is the unscheduled train, whose operating frequency fluctuates with origin-destination (OD) demands; the other is the scheduled train, which is running based on regular timetable just like the passenger trains. The timetable will be released to the public if determined and it would not be influence...
متن کاملSecurity-Aware Network Analysis for Network Controllability
Although people use critical, redundant and ordinary categories to concisely distinguish the importance of edges in maintaining the controllability of networks in linear timeinvariant (LTI) model, a specific network analysis is still uncertain to confirm edges of each category and guide further edge protection. Given a large, sparse, Erdős-Rényi random digraph that is in LTI model and has a kno...
