Resilience management problem in ATM systems as a shortest path problem

摘要

As a preliminary study about the methodology for resilience management in ATM systems, this paper identifies the key aspects that should be taken into account in the formal definition of the problem. It provides an overview of the definitions and concepts related to resilience in ATM systems. Finally, the paper introduces a proposal for a definition of a resilience metric for an ATM system and formally states the resilience management problem as an optimization problem. The latter aims at finding an optimal scheduling strategy for the re-allocation of system tasks. The paper also inspects the nature of the proposed metric, highlights the constraints of the problem and makes a comparison with other approaches. A specific Case Study is discussed in detail in the paper, which allows to demonstrate the applicability of the proposed methodology. Results discussed in the paper can foster the studies on the resilience of the ATM system through a task re-allocation approach. (C) 2016 Elsevier Ltd. All rights reserved.
