Robustness of controllability and recoverability of complex networks

Network robustness describes a network's ability to provide and maintain an acceptable level of service in the face of failures and challenges to normal operation. Unfortunately, failures of networks, such as power outages in power systems, congestions in transportation networks, failures of routers on the Internet, happen frequently in our...

The recoverability of network controllability

Network recoverability refers to the ability of a network to return to a desired<br/>performance level after suffering malicious attacks or random failures. A system is controllable if it can be driven from any arbitrary state to any desired state in finite time under the control of the driver nodes, which are attached to external inputs. We use...

Topological Approach to Measure the Recoverability of Optical Networks

Optical networks are vulnerable to failures due to targeted attacks or large-scale disasters. The recoverability of optical networks refers to the ability of an optical network to return to a desired performance level after suffering topological perturbations such as link failures. This paper proposes a general topological approach and...

The Recoverability of Network Controllability

Network recoverability refers to the ability of a network to recover to a desired performance level after suffering topological perturbations such as link failures. The minimum number of driver nodes is a typical metric to denote the network controllability. In this paper, we propose closed-form analytic approximations for the minimum number of...

Topological Approach to Measure Network Recoverability

Network recoverability refers to the ability of a network to return to a desired performance level after suffering malicious attacks or random failures. This paper proposes a general topological approach and recoverability indicators to measure the network recoverability in two scenarios: 1) recovery of damaged connections and 2) any...

The recoverable robust stand allocation problem: a GRU airport case study

This paper presents an innovative approach to the tactical planning of aircraft remote and contact-stands allocation at airports. We use the concept of recoverable robustness to obtain a recoverable robust solution to the stand allocation problem, a solution that can be recovered by limited means for the included scenarios. Four objective...

Portfolio Scheduling for Risk Management in Business-Critical Workloads Hosted by Cloud Datacenters

Large enterprises and governments shift their long-running and critical operations to run in cloud environments. The on-demand business-critical workloads raise important challenges in datacenter operation, requiring efficient online scheduling of workloads with unprecendented dynamic behavior, yet under strict service level agreements (SLAs)....

Incorporation of Recoverable Robustness and a Commercial Revenue Metric into Tactical Stand Allocation

This thesis deals with an important resource planning problem at airports: the stand allocation problem. More specifically, it is aimed to obtain a robust tactical stand allocation for the airport, at limited cost. We incorporate the concept of recoverable robustness in a stand allocation model and formulate a recoverable robust stand allocation...
